1. Introduction
In recent years, natural disasters triggered by climate risks such as extreme weather, glacial melting, and sea-level rise have caused severe damage to human lives and property. As a result, climate risk has emerged as a major concern for governments and societies worldwide. The
World Economic Forum (
2021) identifies the failure of climate action, the increasing frequency of extreme weather, and environmental degradation driven by human activities as some of the most severe global threats. In the Chinese context, the report of the 20th National Congress of the Communist Party of China emphasizes the strategic significance of ecological civilization and sustainable development, explicitly calling for strengthened climate change mitigation, promotion of green and low-carbon growth, and achievement of the national “dual carbon” targets. In light of both global warming trends and China’s ambitious carbon peaking and neutrality goals, enterprises, as essential participants in the market economy, are increasingly expected to align with national policies, heighten their awareness of climate-related risks, and enhance their capabilities to manage and adapt to these emerging challenges.
Concurrently, the phenomenon of China’s economy “decoupling from the real sector towards the virtual sector” has garnered significant academic attention. At the macro level, this manifests specifically as the continuous rise in the relative proportion of the financial sector within the national economy. At the micro level, financial assets offer relatively higher liquidity and potentially superior returns compared with physical assets, therefore firms may increasingly shift their asset allocation toward financial instruments to ease financial constraints (
Almeida et al., 2004;
Demir, 2009b), pursue short-term earnings (
C. Chen et al., 2023), or participate in shadow banking activities that generate interest spreads (
Shin & Zhao, 2013;
J. Du et al., 2017), which is called corporate financialization. Accordingly, a growing body of literature has explored the drivers and consequences of this trend. Macroeconomic determinants include economic policy uncertainty (
Zhao & Su, 2022) and financial cycles (
Guan & Wei, 2024), while firm-level factors range from interbank competition (
S. Wang et al., 2025) and compensation incentives (
P. Du et al., 2022) to CEO social capital (
Y. Chen et al., 2024). Studies also show that corporate financialization can have adverse economic consequences, such as reduced innovation quality (
Zhu et al., 2023), increased systemic risk (
Rajan, 2006), and greater income inequality (
Hein & Dodig, 2014).
Similarly, climate risk has emerged as a prominent topic of common concern in both academic and practical circles in recent years, and its economic impact on enterprises has also been widely discussed. Overall, existing literature primarily addresses the issue from physical risk and transition risk perspectives. From the perspective of physical risk, extreme climate events such as floods and hurricanes can damage corporate transportation routes and production facilities, leading to an overall decline in business performance. Furthermore, existing research has shown that extreme weather severely impairs the health of outdoor workers (
Flouris et al., 2018;
Parsons et al., 2021), reduces industry working hours (
Somanathan et al., 2021), and increases the intensity of corporate layoffs (
W. Li et al., 2025). From the perspective of transition risk, prior studies have documented that climate risk raises the cost of both debt and equity financing for firms (
Huynh et al., 2020), diminishes corporate profitability (
Pankratz et al., 2023), and imposes additional transition costs as firms respond to increasingly stringent climate regulations (
Seltzer et al., 2022;
Addoum et al., 2023). These factors collectively contribute to prolonged adverse effects on firms’ long-term operational sustainability (
Linnenluecke et al., 2011;
Moscona & Sastry, 2023). Under such circumstances, firms face growing pressure to adopt investment strategies that can effectively mitigate climate-related risks and support sustainable growth.
However, relatively little research has comprehensively investigated the impact of climate risk on firms’ allocation of financial assets. Drawing on the existing literature that connects climate risk with corporate financialization, this study identifies two competing theoretical channels. On the one hand, firms may allocate a higher proportion of financial assets to cope with the uncertainties of climate risk shocks, motivated by the need for “precautionary savings” and to alleviate financial pressures (
Almeida et al., 2004;
Demir, 2009b). On the other hand, climate risks may increase the cost of capital for enterprises and constrain the sources of funding required for their financial investment activities, thereby suppressing corporate financialization. Furthermore, in response to tightening environmental regulations and in pursuit of legitimacy and support from governments, investors, and other stakeholders, firms may redirect their resources toward upgrading energy-efficient infrastructure and strengthening innovation capacity to advance their green transition efforts (
Feng et al., 2024;
Dong et al., 2025), which could diminish their incentives to accumulate financial assets. Despite these conceptual perspectives, empirical evidence on the relationship between climate risk and corporate financialization remains limited. Therefore, our study incorporates firm-level climate risk exposure into the analysis to explore the mechanisms through which climate risk influences financialization behavior. In doing so, it supports the expansion of research into the impact of climate risk on corporate investment decisions, while also providing a foundation for enterprises to cope with climate change.
This paper investigates the impact of climate risk on corporate financialization by employing A-share listed companies in China from 2007 to 2019 as the research sample. The empirical results reveal a significant inverse relationship between climate risk exposure and the extent of financialization, suggesting that firms facing higher climate-related risks tend to engage less in financial asset accumulation. This finding remains robust across multiple verification tests, including instrumental variable estimations, alternative financialization metrics, and expanded temporal frameworks. Further heterogeneity analyses demonstrate that the effect of climate risk on financialization exhibits substantial variation depending on firms’ ownership types, degrees of industry competition, and the stringency of local environmental regulations. Additional mechanism analyses indicate that heightened climate risk reduces financialization by amplifying firms’ financing constraints while simultaneously fostering their innovation efforts. Collectively, these findings suggest that corporate financialization within China’s real sector is largely driven by motives such as investment substitution and real-sector intermediation, which prioritize short-term financial returns over long-term productive investment in the real economy.
The marginal contributions of this study can be summarized as follows: (1) while prior research has largely concentrated on the effects of climate risk on corporate financing constraints (
Huang et al., 2022), firm performance (
Pankratz et al., 2023), and firm valuation (
Berkman et al., 2024), limited attention has been given to the mechanisms through which climate risk shapes corporate investment behavior. To address this research gap, this paper introduces corporate financialization as a novel analytical lens to examine the influence and transmission channels of climate risk, thereby extending the literature on the broader economic consequences of climate-related shocks. (2) Although existing studies on corporate financialization have investigated determinants such as corporate social responsibility (
Su & Lu, 2023), economic policy uncertainty (
Zhao & Su, 2022;
Cheng & Masron, 2024), managerial traits (
Fan & Tang, 2024), and investor risk appetite (
C. Li et al., 2019;
J. Wang & Mao, 2022), few have directly incorporated climate change as a driving factor. By integrating climate risk into the analysis of corporate financialization, and by examining how ownership structure, industry competition, and regional environmental regulation moderate this relationship, this study expands the identification framework and contributes to a more comprehensive understanding of the determinants of corporate financialization. (3) This study reveals that climate risk significantly suppresses corporate financialization through two channels: exacerbating financing constraints and fostering innovation capability. These findings indicate that corporate financialization in China is driven primarily by profit-seeking motives rather than precautionary savings. Such conclusions provide important practical implications for refining China’s financial market mechanisms and facilitating the growth of its real economy. (4) This paper focuses on China as a typical developing country, and its findings may offer valuable insights for other developing nations with similar social systems and economic levels in addressing climate risks and improving financial market mechanisms.
The remainder of the paper is organized as follows.
Section 2 develops the theoretical framework and formulates the empirical hypotheses regarding the impact of climate risk on corporate financialization.
Section 3 describes the research design, including data sources, variable construction, and model specifications.
Section 4 presents the baseline empirical results and conducts a series of robustness tests.
Section 5 investigates the underlying mechanisms through which climate risk influences financialization, focusing on financing constraints and innovation capacity. Finally,
Section 6 concludes the paper and discusses the policy implications.
2. Theoretical Analysis and Research Hypotheses
Theoretical perspectives on corporate financialization are generally classified into three main frameworks: the “reservoir” theory, the “investment substitution” theory, and the “real-sector intermediation” theory. According to the reservoir theory, firms accumulate financial assets as a buffer to alleviate financing constraints and mitigate the costs associated with financial distress. Compared to fixed assets, financial assets, particularly non-cash instruments, possess greater liquidity, allowing firms to liquidate them in times of financial strain to ease funding shortages and reinforce cash flow (
Almeida et al., 2004). Through an analysis of the investment portfolios of non-financial firms in Argentina,
Demir (
2009a) concludes that coping with macroeconomic uncertainty is one of the key reasons for firms to hold financial assets in addition to return differentials. Furthermore, some enterprises utilize financial derivatives for hedging transactions to achieve tax savings and reduce financial distress costs (
Smith & Stulz, 1985;
Bessembinder, 1991).
In contrast, the investment substitution theory emphasizes that financialization is primarily driven by capital arbitrage motives (
Demir, 2009b). When financial investments yield returns that surpass those from real-sector projects, firms are incentivized to reallocate resources from real investment toward financial assets to maximize profits.
Seo et al. (
2012) and
Akkemik and Özen (
2014) conducted studies in South Korea and Turkey, respectively, which confirmed that enterprises tend to increase their investments in financial assets, especially those with high returns, while reducing investment of research and fix assets, which might lead to a “crowding out” effect on the real economy. Furthermore, drawing on upper echelons theory and agency theory, managers with a short-term orientation may exhibit a preference for financial investments that deliver immediate gains at the expense of long-term real-sector development (
Brochet et al., 2015). The real-sector intermediation theory, advanced by
Shin and Zhao (
2013), posits that, under information asymmetry, financial frictions arise between banks and enterprises, resulting in financing constraints when firms seek loans from banks. But low-risk enterprises are more likely to gain favor with banks and therefore face relatively lighter financing constraints, whereas high-risk enterprises tend to be marginalized and encounter more severe restrictions on financing. Therefore, the firms with strong access to external capital and relatively low borrowing costs may engage in shadow banking activities. In doing so, they function as quasi-financial intermediaries, channeling funds to financially constrained and higher-risk firms.
In summary, while financialization driven by the reservoir motive can stabilize corporate operations and ultimately support the real economy, financialization prompted by investment substitution or real-sector intermediation often crowds out real investment, thereby hindering sustained economic growth.
Building upon the three theoretical motivations for corporate financialization discussed earlier, this study explores how climate risk may influence firms’ financialization behavior. On one hand, prior studies indicate that climate risk has increasingly attracted the attention of investors (
Seltzer et al., 2022) and has become an important determinant in the pricing of financial assets such as stocks and bonds (
Huynh et al., 2020). Elevated climate risk amplifies firms’ exposure to systematic uncertainty, affects market sentiment and investor confidence, raises the discount rates applied to investment projects, and reduces the scope of viable investment opportunities (
Y. Li & Wan, 2025). These factors, in turn, increase the likelihood of corporate default (
Bell & Van Vuuren, 2022) and elevate the cost of both debt and equity financing. When confronted with tightening financing conditions, firms may respond differently depending on their financialization motives. Under the “reservoir” motive, firms tend to increase their holdings of financial assets to serve as liquidity buffers against future investment uncertainties. Conversely, under the “investment substitution” and “real-sector intermediation” motives, rising financing costs reduce the attractiveness and feasibility of financial investments by limiting available capital, thereby constraining corporate financialization.
On the other hand, as climate-related challenges intensify, governments are increasingly likely to implement more stringent environmental regulations. In line with the Porter hypothesis, tighter regulatory frameworks may compel firms facing heightened climate risks to strengthen their technological innovation efforts as a means of reducing their exposure and vulnerability. For example,
Xie and Li (
2024) found that cities facing higher climate risks can significantly enhance energy-saving innovation technologies through increased energy consumption, research, and government regulation. At the same time, growing public awareness and heightened investor concern regarding climate risks further motivate firms to pursue innovation, not only to enhance their reputational standing but also to signal proactive climate risk management and foster stronger relationships with key stakeholders (
Hahn et al., 2015), thereby improving their adaptive capacity in the face of climate change. As emphasized by
Feng et al. (
2024), firms that disclose more climate risk information are able to build stronger reputation capital, which subsequently contributes to enhanced innovation capabilities. Furthermore, the operational efficiency gains and improved real-sector returns generated through enhanced innovation may diminish firms’ incentives to pursue financialization through “investment substitution” or “real-sector intermediation” motives, ultimately curbing excessive financial asset allocation. Based on this theoretical foundation, the following research hypotheses are proposed.
Hypothesis 1a. If the “reservoir” motive dominates, climate risk will promote corporate financialization.
Hypothesis 1b. If the “investment substitution” and “real-sector intermediation” motives dominate, climate risk will inhibit corporate financialization.
Hypothesis 2. Financing constraints and innovation capability mediate the relationship between climate risk and corporate financialization.
6. Conclusions and Policy Recommendation
6.1. Conclusions
This paper examines the effect of climate risk on corporate financialization and explores its underlying transmission mechanisms using a panel of Chinese A-share listed firms over the period 2007 to 2019. The empirical results consistently demonstrate that climate risk significantly dampens the extent of financialization, and this relationship remains robust across multiple sensitivity analyses. Heterogeneity tests further reveal that the suppressive effect is more pronounced for state-owned enterprises, firms operating in highly competitive industries, and those located in regions with stricter environmental regulatory regimes. The mechanism analysis identifies two primary channels through which climate risk constrains financialization: by tightening firms’ financing constraints and by promoting innovation capacity. Collectively, these findings suggest that financialization among Chinese non-financial firms is predominantly driven by short-term profit-seeking motives, including speculative investment substitution and real-sector intermediation, rather than by precautionary saving objectives.
6.2. Policy Recommendation
These findings yield several important policy implications that speak directly to the role of climate risk in shaping corporate financialization behavior. Although climate risk itself does not directly induce financialization or amplify financialization trends, the persistent presence of credit discrimination tied to firms’ climate risk exposure highlights structural distortions in capital allocation.
Addressing this issue requires policymakers to strengthen climate risk disclosure mandates, promote the development of independent and credible climate risk assessment institutions, and reduce information asymmetry between firms, investors, and financial intermediaries. First of all, the policymakers should formulate clear standards for climate risk information (such as ESG information) disclosure to enhance the comparability of the information. Secondly, policymakers should establish a regulatory framework for climate risk disclosure to ensure accurate and timely reporting. After that, the policymakers should improve the third-party audit system by encouraging their participation in the review of climate risk information disclosure, thereby enhancing the reliability of the disclosed information. Improving climate risk disclosure and scoring mechanisms holds significant guiding importance for regulators, creditors, and enterprises. For regulatory agencies, it provides comprehensive data that enables accurate assessment of the environmental impact, social risks, and governance gaps across economic activities, thereby supporting the formulation of more scientific and targeted policies. For financial institutions, it reduces information asymmetry between creditors and borrowers. Incorporating ESG risks into credit assessment models allows for more accurate risk pricing, while continuous monitoring of borrowers’ ESG rating changes facilitates dynamic risk evaluation. For enterprises, those with strong ESG performance and high ratings are more likely to attract investors and banks, enabling them to issue bonds or secure loans at lower interest rates, which directly reduces financing costs. In addition, greater transparency in climate-related information is essential for mitigating credit discrimination, improving the allocative efficiency of financial markets, restoring the core function of financial intermediation, and channeling financial resources more effectively toward real-sector investment.
Moreover, the finding that climate risk suppresses financialization primarily by tightening financing constraints suggests that firms are not engaging in financial asset allocation out of precautionary liquidity motives but rather are limited by constrained access to external capital. In this regard, policymakers should continue to develop financial market infrastructure, expand derivative markets, and broaden the range of risk management instruments available to firms. For example, policymakers can encourage financial institutions and enterprises to innovate climate risk derivatives such as climate futures and options to help businesses hedge against climate-related risks. At the same time, the policymakers should expand financing channels for low-carbon transition enterprises and use the supply chain finance to enhance financial services for these companies. Furthermore, the policymakers should establish relevant regulations to provide a transparent legal environment for the climate risk derivatives market, thereby reducing trading risks for low-carbon transitioning enterprises. Strengthening financial market completeness would allow firms to utilize financial assets more effectively as liquidity buffers and to diversify their exposure to climate-related uncertainties without excessive reliance on financialization for short-term arbitrage.
In addition, the mechanism analysis underscores that innovation capacity serves as a key pathway through which climate risk influences financialization behavior. Specifically, stronger innovation capability enables firms to enhance real-sector returns and reduces their dependence on financial asset investments. To foster this adjustment, policymakers should implement supportive measures such as targeted tax incentives, preferential financing policies, and transition subsidies that facilitate firms’ low-carbon transformation and lower adjustment costs. Encouraging sustained R&D investment not only strengthens firms’ technological competitiveness but also activates the innovation compensation effect embedded in environmental regulation, thereby aligning environmental objectives with long-term real-sector growth.
Collectively, these findings contribute to the broader climate finance research by providing novel empirical evidence on how climate risk reshapes corporate financialization through the joint channels of financing constraints and innovation incentives. The results offer meaningful insights for policymakers seeking to balance climate goals with financial stability while ensuring that financial markets continue to serve their essential role in supporting sustainable economic development in the face of escalating climate challenges.
6.3. Limitation and Future Research Outlook
This study has several limitations as follows: first, the existing literature has not yet proposed firm-level instrumental variables for climate risk, and the firm-level instrumental variables constructed in this study are based on heteroscedasticity, therefore, identifying appropriate firm-level instrumental variables in future research could further improve the robustness of the endogeneity tests. Second, while this paper identifies financing constraints and innovation capability as mechanisms through which climate risk suppresses corporate financialization, there may be other underlying mechanisms that researchers could explore in future studies. Third, the sample period ends in 2019 to avoid the impact of the COVID-19 pandemic on the empirical results, but it is worth noting that, after the pandemic, China’s climate policies and economic development models have undergone certain changes, and corporate motivations for holding financial assets may also have shifted. Nonetheless, due to the relatively insufficient number of firm observations in the post-pandemic period, this study does not provide an in-depth analysis of corporate financialization behavior after COVID-19. Finally, this study focuses on China, a typical developing country, and its findings can provide empirical insights for other developing countries with similar socio-economic systems, however, the conclusions may not be generalizable to countries with different social systems or stages of economic development. Researchers may extend this field of study by examining such countries in the future.
