Abstract: In this paper we investigate the relationship between family ownership structure and corporate value across a sample of 1314 firm-year observations of China’s family publicly listed companies (PLCs), from 2004 to 2008. We find a significant inverse-U-shaped relationship between the controlling family’s ultimate cash-flow rights and corporate value; as measured by Tobin’s Q. That is, as family-ownership concentration increases, corporate value first increases and then decreases. This finding refreshes our understanding of the relationship between family-ownership concentration and corporate value in emerging economies such as found in China. We corroborate prior findings that when controlling families hold excess control over cash-flow rights, corporate value is significantly lowered, while multiple large shareholders structure is significantly associated with higher corporate value. In addition; board independence is found to significantly improve corporate value in the context of family-concentrated ownership. We also test for potential endogeneity between family ownership and corporate value and find our results to be robust.
Since China’s economic reform began in 1978, China has become the largest and fastest-growing emerging economy in the world (Allen et al. ). During the past three decades, China’s economic reform has seen declining state ownership and rising private sector ownership (Ding et al. ). As the private sector has developed substantially, the Chinese stock market has been increasingly listing family-controlled firms. However, research has provided little understanding about family ownership in Chinese publicly listed companies (PLCs). In this study, we explore empirically the governance effect of family-concentrated ownership in China’s unique institutional context. In particular, we describe and compare the ultimate ownership structures in Chinese state-owned and family PLCs, and then analyze the relationship between family ownership structure and corporate value in Chinese family-controlled PLCs.
Concentrated ownership is common throughout the world (Claessens et al. , Faccio and Lang , La Porta et al. ), especially in emerging economies, such as found in China. On one hand, minority shareholders may show free-ride behaviors, but large shareholders have the incentive and voting power to collect information, monitor the management, and, thus, improve corporate value (Grossman and Hart , Jensen and Meckling ). On the other hand, large shareholders have a general interest and enough control to pursue their own benefits at the expense of minority shareholders (Alsan and Kumar , Shleifer and Vishny ), especially when large shareholders with relatively smaller shares, nevertheless, control the firms through control-enhancing mechanisms, such as a pyramid structure, cross-holding, and dual-class shares (Adams and Ferreira , Lin et al. [11,12], Johnson et al. , Friedman et al. ). As ownership concentration increases, large shareholder’s interests may become more aligned with minority shareholder interests and, thus, reduce the likelihood and degree minority shareholders would be expropriated (Claessens et al. , Dyck and Zingales ). That is, ownership concentration and corporate value may have a positive linear relationship (La Porta et al. , Claessens et al. ).
However, in practice, many of China’s controlling families use their high ownership to expropriate minority shareholders, ultimately reducing corporate value. Controlling families respond, not only to firm-level imperatives, but also to country/region level institutions. In particular, emerging economies, such as China’s, are in the process of economic reform. Their formal institutions are in transition, and legal system for protecting investors and enforcing protections are still weak and uneven. In this special institutional context, controlling families have low cost and little risk of being captured for expropriating minority shareholders and are, thus, prone to pursue their own utility at the expense of minority shareholders, causing serious conflicts of interests. High ownership is accompanied by high voting rights. Without effective power balance from other large shareholders, high ownership does not always align controlling family interests with minority shareholder interests in emerging economies. Hence, family-ownership concentration and corporate value should have a non-monotonic relationship rather than a simple linear relationship (Bai et al. , De Miguel et al. , Morck et al. , Tian and Estrin , Yeh et al. ). However, thus far, we know little about relationships for ultimate family-ownership structure in China.
Accordingly, we use a panel data set of 1,314 firm-year observations from Chinese family-controlled PLCs from 2004 to 2008. Consistent with our argument and prediction, we find strong evidence of a significant nonlinear inverse-U-shaped relationship between ultimate family ownership and corporate value in China. As the level of ultimate family ownership increases, corporate value, as measured by Tobin’s Q, first increases and then decreases. That is, family-concentrated ownership has two competing effects: interest-alignment and entrenchment. The level of family ownership determines which effect dominates.
Similar to prior findings (e.g., La Porta et al. , Yeh et al. , Yeh ), we find that diverging control and cash-flow rights significantly and negatively affect corporate value. Meanwhile, of several other governance mechanisms, we find that only multiple large shareholders structure and strong board independence conditions are significantly associated with higher corporate value. These findings suggest that in the context of concentrated ownership, multiple large shareholders and independent directors provide the power and balance to play an effective governance role in restricting the controlling family’s expropriation activities. Nevertheless, other governance mechanisms, such as management ownership and CEO duality, play a limited role (Berglöf and Pajuste , Claessens and Fan , Morck et al. ). As a result, our findings have important implications for corporate governance practice in China and other emerging market economies.
We make three main contributions to the literature. First, we enrich the growing map of ultimate ownership structures around the world by describing and comparing in detail ultimate corporate ownership structures between China’s family-owned and state-owned PLCs and between PLCs in China and in other East Asian Economies (Claessens et al. , Faccio and Lang , La Porta et al. ). Second, because evidence is mixed regarding the influence of family ownership on firm performance/value (e.g., Anderson and Reeb , Andres , Goergen , Morck et al. ), we argue that family ownership and corporate value have a non-monotonic relationship rather than a simple linear relationship, and then find strong and robust corroborating evidence from a sample of data from China’s family-controlled PLCs. Thus, we contribute to the literature by suggesting that the level of family-ownership concentration changes the dominant interest-alignment and entrenchment effects of family-concentrated ownership. Third, we find that traditional governance mechanisms are inadequate in the context of concentrated ownership. Instead, different governance mechanisms, such as multiple large shareholders and independent directors, are required to resolve conflicts of interests between the controlling families and minority shareholders.
The rest of this paper is structured as follows. Section 2 briefly introduces the ultimate ownership structures of Chinese PLCs. Section 3 drives our testable hypotheses. Section 4 describes the data set and variables. Section 5 presents regression results. Section 6 concludes.
2. Ultimate Ownership Structures of Chinese PLCs
In 1978, China undertook economic reform to turn its central-command economic system into a market economy. Since then, China has become the world’s largest and fastest-growing emerging economy (Allen et al. ). During the past three decades, China’s economic reform has led to the decline of state ownership and the rise of private sectors (Ding et al. ).
In the early 1990s, the Chinese government launched SOEs reform to clarify former SOEs’ property rights, improve their corporate governance, and promote their operating performance. To restructure and renovate former SOEs, especially to help SOEs raise funds, the Chinese government established the stock market. As a result, many former SOEs were restructured to form joint stock companies. However, central or local governments still control former-SOE joint stock companies (Ding et al. ). To decentralize control rights from the State to firm managers who specialize in managing state assets no longer diluted by state ownership in case of losses, the government usually owns the listed companies through a pyramidal structure consisting of one to several intermediate companies, generally non-listed, solely government-owned SOEs (Fan et al. , Watanabe ). That is, Chinese state-owned PLCs commonly feature pyramidal ownership structures with weak divergence between ultimate cash-flow and control rights (see column B in Table 1).

As economic reform has deepened in China, many private firms have emerged to become increasingly important to the rapid economic development. In 1992, with the first private-owned company listed on the Chinese stock market, a small but increasing number of private-owned firms, especially family-controlled firms, have been listed on the Chinese stock market (Ding et al. , Fan et al. ). For example, by the end of 2008, the Chinese stock market had about 387 family-controlled PLCs, about 34.43% of the total number (1124) of non-financial listed companies (see column B in Table 1). To create internal capital markets and thus relieve financial constraints, entrepreneurs/families also control these PLCs through pyramids. However, entrepreneurs/families usually lack full ownership of the intermediate companies, along the pyramids, resulting in huge divergence between their ultimate control and cash-flow rights (Fan et al. ).
Although China’s state-owned and family-owned PLCs commonly have pyramidal structures, ultimate ownership structures differ. As column B of Table 1 shows, state-owned PLCs have much higher ultimate-ownership concentration than do family-owned PLCs. In state-owned PLCs, the largest shareholder’s ultimate control and cash-flow rights diverge much less than they do in family-owned PLCs, as indicated by the ratio of ultimate cash-flow rights to control rights. Column A of Table 1 also shows that in ten countries/regions of East Asia, the ratio of controlling families’ ultimate cash-flow rights and control rights, a reverse estimator of the divergence between ownership and control, is the second lowest in mainland China (0.67) with the lowest in Japan (0.60). This indicates common and serious disproportional ownership in Chinese family-owned PLCs, and indicates serious possible conflicts of interests between controlling families and minority shareholders (Friedman et al. ).
Due to different ultimate ownership structures for state-owned and family-owned PLCs in the Chinese stock market, previous findings on ownership concentration and corporate value/performance relationships drawn from samples combining Chinese state-owned and family-owned firms would be problematic and unconvincing (e.g., Bai et al. , Tian and Estrin , Wei et al. ). As a result, we focus on Chinese family-owned PLCs to gain more knowledge about ultimate family ownership structures and draw convincing comparable results regarding relationships between family-concentrated ownership and corporate value in China.
3. Hypotheses Development
Unlike cases of diffuse ownership, universal large shareholders can help resolve traditional agency problems between shareholders and managers, but would also cause conflicts of interests between majority shareholders and minority investors (Grossman and Hart , Jensen and Meckling , Shleifer and Vishny [9,34]). In other words, family-ownership concentration has two competing effects: interest-alignment and entrenchment (Claessens et al. , Dyck and Zingales ).
Under low family-ownership concentration, entrenchment effect will be very weak so that conflicts of interests between controlling families and minority shareholders would generate relatively low costs. As controlling families would lack the voting rights to expropriate minority shareholders, interest-alignment effects may turn to be pronounced. As early as 1980, some degree of ownership concentration was suggested to help resolve problems of free-riders in monitoring managers (Grossman and Hart ). In contrast, small investors often “vote with their feet” when a firm is performing poorly, so block shareholders (i.e., controlling families in this study) have enough voting power and incentives to collect information and monitor managerial opportunistic behaviors and then help resolve traditional agency problems between shareholders and managers (Andres , Grossman and Hart , Jensen and Meckling , Shleifer and Vishny [9,34]). In emerging economies, such as in China, this interest-alignment effect of family-concentrated ownership may be much more pronounced. Conflicts of interests between shareholders and managers is much more serious in emerging economies because of poor legal systems, uneven enforcement (North ), and developing corporate governance.
However, under highly concentrated family ownership, controlling families may expropriate firm resources for their own utility at the expense of minority shareholders. As high ownership concentration enables controlling families to manipulate and even appoint management, they can more easily pass privately beneficial decisions/proposals at the expense of overall corporate value. Meanwhile, high ownership concentration means that minority shareholders or coalitions of minority shareholder are weak in the power balance, and thus have no effective restrictions to counter self-beneficial behaviors. In other words, high family-ownership concentration may have a dominant entrenchment effect; controlling families and minority shareholders have serious interest conflicts with resulting poor corporate value. In emerging economies with weak institutions, the entrenchment effect will be more marked. For instance, in China, controlling families usually have outright firm control and management through pyramidal structures (Fan et al. ), making them much more powerful and able to use their super voting rights to appropriate the profits of companies lower on the tier.
Combining the interest-alignment and entrenchment effects of family-concentrated ownership, we suggest that as family ownership concentration gradually increases, corporate value first increases and then decreases, reflecting an inverse-U-shaped relationship between family ownership and corporate value. Those observations generated our first testable hypothesis:
Hypothesis 1: An inverse-U-shaped relationship will occur between family-concentrated ownership and corporate value.
Ultimate ownership structure also leads to the divergence of control and cash-flow rights. In Chinese state-owned PLCs, the government often directly/indirectly controls 100% of ownership (Watanabe ; also see the data in Table 1), however, in Chinese family-controlled PLCs, controlling families usually use pyramidal structures to control listed firms with relatively small ownership, so that control and ownership sharply diverge (Fan et al. ). Thus, ultimate ownership structures in Chinese family-controlled PLCs are distinct in the separation of control and ownership. Under this practical background, controlling families have much incentive to tunnel the lower-tier listed firm’s profits and resources because other shareholders will bear the major tunneling costs, but expropriation provides exclusive benefits (Aslan and Kumar , Faccio et al. , Friedman et al. ). Thus, the major portion of the costs of tunneling will be born by controlling families and minority investors have worsened interest conflicts and increased agency costs (Claessens et al. , Lin et al. [11,12], Yeh et al. , Yeh ). As a result, aligned with prior studies (Claessens et al. , Dyck and Zingales , La Porta et al. ), the huge divergence between controlling families’ ultimate control and cash-flow rights would reduce corporate value, leading to our second testable hypothesis:
Hypothesis 2: The more divergence between controlling families’ ultimate control rights and cash-flow rights, the lower will be corporate value.
4. Research Design
4.1. Sample and Data
For our sample set, we gathered data regarding family-controlled PLCs in the 2004 to 2008 Chinese stock market. We defined companies as family-controlled PLCs if families or individuals were the largest PLC shareholders, with no less than 10% of ultimate control rights (Le Breton-Miller and Miller ). Second, the China Securities Regulatory Commission (CSRC) required Chinese PLCs to disclose details of control chains until 2003. Only a few PLCs disclosed this information in the first year, thus, we took 2004 as our initial sample year and selected firm-year observations from 2004 to 2008. Third, the government always treats the financial industry as a special domain and requires the industry to comply with very stringent legal requirements, thus, we eliminated all financial companies. Finally, to minimize outlier influences, we deleted firms also listed on other overseas markets, firms with issued debt more than asset value, firms that are under Special Treatment (ST), and firms with missing data. We finally obtained a five-year panel data set of 1314 firm-year observations. Firms in each sample year for 2004 to 2008 numbered 162, 183, 268, 314, and 387, respectively. In this study, we followed CSRC’s Guidelines for Classification of Listed Companies (A through M) to classify our sample industry, including all but the financial industry.
We obtained financial data from the China Stock Market & Accounting Research (CSMAR) database designed and developed by GTA Information Technology, a major provider of China data. We hand-collected data about PLC control chains from PLC annual reports disclosed on the CRSC-appointed CNINFO website.
4.2. Variable Description
Since Tobin’s Q is a widely used measure of valuation for listed companies, we followed this tradition and took Tobin’s Q to measure the dependent variable: corporate value. Following previous researches (Wei et al. , Tian and Estrin ), we calculated Tobinq as the ratio of the market value of equity plus the book value of debt over the book value of total assets. However, Chinese PLC stock is classified as tradable and non-tradable. Illiquidity discounts of 70%–80% present a problem for pricing non-tradable stock (Chen and Xiong ). Referring to Bai et al. , we multiplied the tradable stock price by 30% and 20%, respectively, to use as the price of non-tradable stock and, thus, acquired another two measures for corporate value: Tobin70 and Tobin80, respectively. As a whole, we used three alternative measurements for corporate value in this study: Tobinq, Tobin70, and Tobin80.
The independent variables are the controlling family’s ultimate cash-flow rights and the divergence between the controlling family’s ultimate control and cash-flow rights, denoted by family ownership and wedge of control and ownership, respectively. Pyramidal ownership structure is predominant in the Chinese stock market (Fan et al. ), so we cast back the firm’s control chains and used La Porta et al.’s  method to calculate controlling families’ ultimate cash-flow and control rights. Specifically, we computed controlled families’ ultimate cash-flow rights as the sum of the product of the equity stakes along the control chains. The ultimate control rights were computed as the sum of the minimum voting stakes along the control chains. Then, wedge of control and ownership was measured as the ratio of the controlling family’s ultimate control rights and cash-flow rights (Faccio and Lang ). Table 2 presents the definitions of other governance variables and control variables.

4.3. Empirical Model Specification
To test our two hypotheses relative to the relationships between family ultimate ownership structure and corporate value, we used the following regression model:
For our five-year panel data set, we used the fixed effects method to estimate our regression models. Ultimate family ownership structure changed substantially over the sample period, and by nature, the fixed effects model requires longitudinal variation in the data (Andres ). Therefore, this equation can identify fixed effects. In addition, we used fixed-effects IV regression models to address endogeneity issues between family-ownership structure and corporate value.
5. Empirical Results
5.1. Descriptive Results
Table 3 presents the descriptive statistics of the data and shows that the average corporate value, measured by Tobinq, was 2.22, much lower than 2.99 (in Bai et al. ), 2.92 (in Wei et al. ), and 2.68 (in Tian and Estrin ). The latter three studies included both family and state-owned PLCs in their samples, which suggests that family-owned PLCs have much lower corporate value than do state-owned PLCs in China. Meanwhile, controlling families’ ultimate cash-flow rights averaged about 23.8%, and their ultimate control and cash-flow rights averaged 2.06, indicating that Chinese family-controlled PLCs have high ownership concentration and largely diverging ultimate control and cash-flow rights. Of the total sample firms, 70.7% had more than one large shareholder with no less than 5% ownership. On average, about 35.8% of directors were independent, much lower than that in developed Western countries. In the sample firms, top managers owned an average of only 2.1% of their companies’ shares. Only 18.0% of the CEOs were also either chairmen or vice chairmen of the board of directors, much lower than 35% when both family and state-owned PLCs were included (in Bai et al. ). This result means that Chinese state-owned PLCs much more frequently have dual CEOs and (vice) chairmen on their boards of directors.
More specifically, to derive more insightful knowledge about ultimate family-ownership structure in Chinese PLCs, we summarized yearly statistics for family-ownership structure over the sample period of 2004 to 2008. Table 4 shows the results indicating that controlling families’ ultimate cash-flow rights decreased yearly, from 2004 to 2006, but markedly increased from 2007 to 2008. However, controlling families’ ultimate control and cash-flow rights diverged increasingly each year in the first three years, but substantially decreased in the last two years. For example, controlling families reaches their lowest average ultimate cash-flow rights of 20.3% in 2006 but the highest of 27.6% in 2008, while their ultimate control and cash-flow rights have their highest average ratio of 2.37 in 2006 but their lowest of 1.78 in 2008. Thus family ownership structure in Chinese PLCs changed substantially during the sample period of 2004 to 2008. This change predominantly tended toward the weakening divergence of control and cash-flow rights.

Table 5 shows the correlation coefficients between main variables included in regression models, illustrating that the absolute values of correlation coefficients are much smaller than 0.5 except for the coefficients among our three alternative corporate value measurements. Hence, multicollinearity does not appear to be a significant problem in this study.

5.2. Regression Results
Table 6 reports the results of fixed-effects (within) regressions of family ownership on our three corporate value measures of Tobinq, Tobin70, and Tobin80. In Models 1 and 2 we used Tobinq as the measure of corporate value, Models 3 and 4 used Tobin70, Models 5 and 6 used Tobin80. In all models, we included control variables (e.g., Firm size, Firm age, Firm leverage, Tangible assets, ROA, Sale growth) commonly used in studies of corporate value, as well as year dummy variables and industry dummy variables.

As Table 6 displays, when the regressions included only Family ownership, we found no significant relationship between family ownership and corporate value (see Models 1, 3, and 5 in Table 6). However, when we included family ownership and family ownership squared into the regressions at the same time, family ownership had positive and almost significant coefficients for our three corporate value measures, and family ownership squared had negative and significant coefficients at the 1% level (see Models 2, 4, and 6, in Table 6). These findings indicate that in China, a nonlinear inverse-U-shaped relationship, rather than a linear relationship, occurs between family-concentrated ownership and corporate value, consistent with hypothesis 1. Using the coefficients of family ownership and family ownership squared from Model 4 and taking Tobin70 as the measure of corporate value, we got the turning point of the nonlinear inverse-U-shaped relationship. On the turning point, family ownership equals approximately 33.27%. This value implies that a positive relationship occurs between family ownership and Tobin70 when controlling families’ ultimate ownership is below 33.27%, the interest-alignment effect of family-concentrated ownership, but a negative relationship occurs between family ownership and Tobin70 when the controlling family’s ultimate ownership is no less than 33.27%, the entrenchment effect of family-concentrated ownership.
Our results are more or less consistent with previous research in Canada, family ownership was found to be negatively related financial performance (Morck et al. ). In another study, panel data on S&P 500 firms showed firm performance and family holdings to have a nonlinear but inverted-U-shape (Anderson and Reeb ). Panel data on 275 German listed companies showed family ownership to be significantly and positively related with accounting performance, but slightly significantly related with market valuation through a 10%-level nonlinear relationship (Andres ). Combining the evidence, we argue that low levels of family-concentrated ownership can help resolve agency problems between shareholders and managers, but high levels of family-concentrated ownership and thus outright control might allow owners to expropriate minority shareholders to maximize their own utility, especially in emerging economies, such as China’s, where legal investor protections are poor. However, our findings sharply contrast with three studies on state shareholdings in China (Bai et al. , Wei et al. , Tian and Estrin ) that find a nonlinear-U-shaped relationship between state shareholdings and corporate value. Those differing results may occur mainly from different ownership state-owned and family-controlled structures in the Chinese stock market (see Table 1). Once again, to avoid drawing murky and inconsistent conclusions, future researchers focusing on the issues of Chinese corporate ownership structure should be aware that Chinese state-owned and family-controlled companies are vastly different.
In terms of the divergence of the controlling family’s ultimate control and cash-flow rights, the Wedge of control and ownership coefficients were negative in all regression models, as Hypothesis 2 predicts. However, only some are statistically significant (see Models 3 and 5, in Table 6). As a whole, hypothesis 2 is weakly supported. That is, the divergence of controlling families’ ultimate control and cash-flow rights may exacerbate the expropriation of minority shareholders and thus reduce corporate value in China, which coincides with prior studies (e.g., Claessens et al. , Lemmon and Lins , Lin et al. [11,12], Maury , Yeh ).
In the context of concentrated-ownership structure, do traditional governance mechanisms play an effective governance role and affect corporate value? To answer that question, we examined the effects of four most-frequently mentioned governance variables on corporate value. As Table 6 shows, the Multiple large shareholders variable was positively related to corporate value in all regression models, but only significantly related to corporate value, as measured by Tobinq (see Models 1 and 2). Overall, the results indicate that multiple large shareholders are associated with higher corporate value, consistent with previous empirical findings (Attig et al. , Maury and Pajuste ). The proportion of independent directors on the boards had positive coefficients in all regression models, which is significant at least at the level of 5%. Hence, our findings strongly indicate that board independence can play an effective governance role in preventing controlling families from expropriating minority shareholders, thus improving corporate value. More specifically, our findings suggest that although the independent director system has a short history in China, it is now mature enough to play an effective governance role as intended in Chinese PLCs. In addition, we found no significant effects of management ownership and CEO duality on corporate value, indicating that the two traditional governance factors do not affect corporate value. Taken as a whole, the role of traditional internal governance mechanisms is much limited in the context of concentrated ownership (Berglöf and Pajuste , Claessens and Fan , Morck et al. ).
Of the six control variables, the nature log of total assets (Firm size) was negatively associated with corporate value at the 1% level of significance in all regression models. This result corroborates previous findings (e.g., Bai et al. , Tian and Estrin , Wei et al. ) and indicates that smaller firms have higher corporate value in the Chinese stock market. Similar to prior evidences, ROA positively affects corporate value at the 1% level of significance in all regression models, suggesting that better accounting performance is associated with higher corporate market performance in Chinese family-controlled PLCs. However, our results show no signs of significant and consistent effects of Firm age, Firm leverage, Tangible assets, and Sales growth on corporate value in the Chinese stock market.
5.3. Analysis of Endogeneity of Family Ownership and Corporate Value
Our results potentially suffer from an endogeneity issue: our observed relationship between family ownership and corporate value might be the result of reversed causality. Ownership structures are firm-specific and affected by compensation plans, insider trading possibilities, and corporate takeovers (Demsetz and Lehn , Demsetz and Villalonga ), which indicates that firm performance/value affect the ownership structure. In our study, family ownership might be an endogenous variable. However, the argument for the endogeneity of family ownership is questionable. Many empirical findings (e.g., Andres , Gugler and Weigand , Holderness , La Porta et al. ) suggest that ownership structures, especially large shareholder ownerships, are relatively stable over time. Hence, it seems unlikely that large family shareholders will change their ownership quickly and frequently in light of the firm’s temporary market valuation.
Despite the questionable argument of the endogeneity issue, we tested the robustness of our results by employing an IV-2SLS panel-data model; that is, fixed-effects (within) IV regressions. Specifically, the ultimate cash-flow rights of family-controlling shareholders (family ownership) are instrumented by lagged value in all regressions. Table 7 shows the regression results drawn by this method. After controlling for endogeneity, the inverse-U-shaped relationship between family ownership and corporate value was still significant for all three measures of corporate value: Tobinq, Tobin70, and Tobin80. The results indicate that serious reversed causality may not occur between family ownership and corporate value. In other words, endogeneity of family ownership does not drive the inverse-U-shaped relationship between family ownership and corporate value drawn in this study.

In this paper, we investigate the relationship between ultimate family-ownership structure and corporate value using a five-year panel data set of 1314 firm-year observations from China’s family-controlled PLCs from 2004 to 2008. Unlike previous studies that propose a simple linear relationship between ownership concentration and corporate value, we argue and find a nonlinear inverse-U-shaped relationship between family ownership and corporate value in China’s emerging economy where minority shareholders have poor legal protection. More specifically, we study the relationships between controlling families’ ultimate cash-flow rights and corporate value, and between the divergence of controlling families’ ultimate control and cash-flow rights and corporate value.
We find significant and consistent results. First, we find that the relationship between the controlling family’s ultimate cash-flow rights and corporate value, as measured by Tobin’s Q, exhibits a significant nonlinear inverse-U-shaped pattern, known as the interest-alignment and entrenchment effects of family-concentrated ownership. That is, the left half of the inverse-U-shaped curve reflects the interest-alignment effect of family-concentrated ownership, while the right half reflects the entrenchment effect. Second, we find evidence of a significant and negative relationship between the divergence of control and cash-flow rights and corporate value, which is consistent with prior studies. Third, we corroborate previous findings that both multiple large shareholders and high board independence are significantly associated with higher corporate value, but other governance mechanisms such as management ownership and CEO duality do not have significant and consistent effects on corporate value. These findings suggest that in the context of concentrated ownership, some traditional governance mechanisms would be ineffective for reducing agency costs and improving corporate value. Finally, our robustness tests of potential endogeneity between family ownership structure and corporate value future suggest that our results are robust.
Our findings add to our understanding of the relationship between family ownership structure and corporate value. Specifically, family-concentrated ownership has two competing effects: interest-alignment and entrenchment. The level of family-ownership concentration determines which effect dominates. In other words, increased family-ownership concentration does not always enhance corporate value. Controlling family-ownership concentration plays its best governance roles at moderate levels. Moreover, in the context of family-concentrated ownership, both multiple large shareholders and high board independence can play effective governance roles by restricting controlling families from expropriating minority shareholders, thus, enhancing corporate value. In practice, our findings suggest regulators (e.g., CSRC in China) should particularly supervise potential expropriation of minority shareholders in family-owned firms where controlling families hold high concentrated ownership, without multiple large shareholders structure, and/or having low board independence. For outside investors, they should avoid investing in family-owned firms with above features.
Despite these theoretical contributions and practical implications, future research should mainly address two limitations of this study. First, besides family ownership, family management is the other side of coin in family-controlled firms. How family management may interact with family ownership in driving firm performance would be an important research question in the future. Second, since firm performance is a complex function of many factors, it deserves research attention to go a step further to explore specific channels through which family-concentrated ownership affects firm performance.
