Abstract

2. Literature Review
3. Mechanism Analysis and Research Hypotheses
3.1. Direct Effect of DVC on SICLU
- (1)
- DIC serves as a crucial support and carrier for digital village and can embed digital technology into agricultural production and operation decisions and enhance data acquisition and sharing in rural areas [53]. According to asymmetric information theory, DIC can broaden information channels and coverage and speed up information transmission, which can reduce information asymmetry in agricultural production and management, thereby increasing factor productivity and SICLU [54]. Moreover, DIC, especially the construction of digital infrastructure for collecting and analyzing farmland and environmental monitoring data, can provide information for precise resource inputs, yield monitoring, and environmental management, which helps to boost yields, avoid excessive input of agricultural chemicals, and decrease agricultural pollution emissions, thus promoting the sustainable development of agriculture and improving SICLU [43].
- (2)
- DRE is the core of DVC and a new driving force for sustainable rural development. DRE improves SICLU mainly by promoting the development of rural digital supply chains and rural digital marketing and the digital transformation of inclusive finance. The advancement of the digital supply chain (the increase in rural logistics networks) and digital marketing (the development of rural e-commerce) could increase the channels for farmers to purchase green agricultural inputs and sell green agricultural products, decrease the transaction costs of agricultural inputs and outputs, and enhance farmers’ green production motivation [55]. This facilitates the implementation of green production technology and the input of green agricultural material, which will reduce negative environmental impacts, thereby promoting sustainability and increasing SICLU [56]. Moreover, digital financial inclusion helps to alleviate the negative impact of capital scarcity in the agricultural sector on the application of new agricultural technology, resulting in an improvement in SICLU [51,57].
- (3)
- According to the digital governance theory, DRG is capable of changing the information asymmetry between governance entities and enhancing the overall efficiency of rural grassroots work through introducing modern information technology [58]. DRG increases the transparency of various agricultural policies, and thereby promotes their implementation by applying digital tools, such as Alipay, WeChat, and DingTalk, in rural grassroots government services in China. This would help to enhance farmers’ enthusiasm for implementing conservation tillage and increase agricultural production efficiency, thus improving SICLU [59,60]. Strict cultivated land protection is a fundamental requirement for rural governance, and cultivated land governance is an important part of rural governance. The digital transformation of cultivated land governance (e.g., the adoption of information technology in farmland fragmentation governance, the ecological restoration of farmland, and high-standard farmland construction) can improve governance efficiency, boost yields, and improve farmland ecological environment, thereby promoting the sustainability of agriculture and SICLU [61,62,63].
- (4)
- DRL facilitates access to more entertainment, education, and other resources in rural areas through Internet platforms, thus affecting SICLU. Specifically, increasingly prosperous online information and gradually popularizing smartphones and computers have provided more opportunities to promote agricultural technology extension and enhance farmers’ digital literacy and skills. This can promote the adoption of digital technology in agricultural cultivation and enhance farmers’ farmland management capabilities, thereby increasing SICLU [43,64]. Moreover, DRL enhances farmers’ awareness of green production through expanding their social networks and channels and promoting the sharing and dissemination of information and knowledge on the green transition of CLU [65,66]. This further encourages the adoption of green farming techniques and reduces the dependence on agricultural chemicals, thereby reducing negative environmental impacts and improving SICLU [44,47,67]. In summary, the following hypothesis is formulated:
3.2. Indirect Effect of DVC on SICLU
3.2.1. The Mediating Role of FI Between DVC and SICLU
3.2.2. The Mediating Role of TI Between DVC and SICLU
3.2.3. The Mediating Role of AgI Between DVC and SICLU

4.2.1. Calculation Method for SICLU
4.2.2. Basic Model
4.2.3. Mediating Effect Model
4.3. Variables Selection
4.3.1. Explained Variable
4.3.2. Explanatory Variable
4.3.3. Control Variables
- (1)
- Multiple cropping index (MCI). The improvement of MCI could increase the utilization ratio of cultivated land, thereby increasing agricultural output and SICLU [96]. However, the enhancement of MCI may increase the input of agricultural chemicals and even lead to the excessive exploitation of cultivated land, thereby increasing environmental loading and agricultural waste and even decreasing cultivated land productivity. This will ultimately decrease SICLU. MCI was measured by the ratio of the total planting area of crops to the cultivated land area [96].
- (2)
- The proportion of the sown area of grain crops (SAGC). Compared with grain crops, cash crops usually require a higher input of agricultural chemicals, thereby producing more agricultural waste and ultimately decreasing SICLU. However, farmers may invest in agrochemicals in grain production to gain more profits, which may threaten SICLU. In this study, SAGC was defined as the proportion of the sown area of grain crops in the total sown area of crops [40].
- (3)
- Per capita cultivated land (CLA). CLA reflects the cultivated land resource endowments in each county. When CLA is relatively low, other types of production materials will be invested in agricultural production as substitutes for cultivated land. This may further affect SICLU. CLA was calculated by dividing the total cultivated land area by the total resident population [97].
- (4)
- Ratio of agricultural employees (PAE). To some extent, PAE reflects the abundance of labor force engaged in agricultural production. A sufficient agricultural labor force may promote the intensive cultivation of farmland, reduce the risk of farmland abandonment, and substitute for the use of some agricultural chemicals, which may be conducive to SICLU. This study selected the proportion of agricultural employees in the rural labor force as the proxy for PAE [98].
- (5)
- Output value per unit area (OVP). OVP reflects the development level of the agricultural economy in a specific region. Agricultural economy development can accelerate the advancement of agricultural technology and scale management of cultivated land, thereby increasing farmland productivity and SICLU. However, as the agricultural economy develops and agricultural production scale expands, agricultural production is confronted with increasing environmental pressure, which is not conducive to improving SICLU. Referring to Cao et al. (2022) [99], the OVP was evaluated as the value added of the primary industry per unit of cultivated land area.

7. Conclusions and Policy Implications
7.1. Conclusions
- (1)
- DVC had a significant promoting effect on SICLU in Chinese counties. This conclusion was still valid after a sequence of robustness tests. Moreover, all four secondary indicators of DVC (DIC, DRE, DRG, and DRL) can significantly improve SICLU. Therefore, the positive effect of DVC on SICLU should not be overlooked.
- (2)
- The effect of DVC on SICLU exhibited evident heterogeneity in different regions. This effect was significantly positive in the eastern and central regions but insignificant in the western region. The main reason may be that the western region’s lagging adoption of digital technologies—attributable to agricultural productivity gaps, technological constraints, and talent shortages—has hindered the development of DVC and digital agriculture, thereby limiting the promotional effect of DVC on SICLU. Additionally, the promotional effect of DVC on SICLU was significant in both regions with abundant and relatively scarce resource endowments; however, this effect is greater in the latter regions.
- (3)
- FI, TI, and AgI were important partial mediating variables through which DVC indirectly improved SICLU. This indicates that the intrinsic mechanisms underlying the relationship between DVC and SICLU are relatively complex. The systematic exploration of the transmission mechanisms of DVC affecting SICLU is conducive to fully leveraging the promotional effect of DVC on SICLU.
7.2. Policy Implications
- (1)
- Given that DVC and its four sub-indices significantly improved SICLU, policymakers should promote DVC in multiple dimensions. More specifically, the government should increase its financial support to improve the digital infrastructure in rural areas, perfect relevant policies to improve the digital supply chain, and accelerate the development of rural e-commerce. Great efforts should be made to accelerate the empowerment of digital technology to modernize rural governance and raise relevant subsidies and provide more free training to enhance farmers’ digital skill levels. Moreover, scholars should conduct in-depth research to examine the limiting factors of DVC, which could provide empirical evidence for optimizing policy design and thereby enhance the effectiveness of DVC. As a result, DIC, DRE, DRG, DRL, and DVC will be promoted. This will facilitate the increase in agricultural productivity and the reduction in carbon emissions and agricultural non-point source pollution, thereby promoting the achievement of SDG 2 (Zero Hunger), SDG 12 (Responsible Consumption and Production), SDG 13 (Climate Action), and SDG 15 (Life on Land), and accelerating the improvement of SICLU.
- (2)
- Considering the heterogeneity characteristics of DVC, SICLU, and their relationship, China should establish a regionally differentiated development strategy to promote DVC and give full play to its role in improving SICLU. For eastern and central regions, it is necessary to summarize the successful experiences and deficiencies of DVC and design optimization strategies to promote it, thereby improving SICLU. The central and local government should accelerate the DVC of the western region and leverage its positive role in improving SICLU by improving related policy support system, accelerating the transfer and transformation of digital technology, and strengthening farmers’ digital literacy.
- (3)
- The mediating effect analysis showed that DVC can improve SICLU through increasing FI, accelerating TI, and promoting AgI. Based on this, we propose further accelerating DVC and tapping into its potential for increasing FI to enhance farmers’ motivation and ability to use green production factors and adopt new technology, thereby helping to improve SICLU. To further enhance the SICLU level, perfecting the agricultural technology innovation system and strengthening agricultural technology training to promote agricultural technology innovation and application should not be overlooked when progressing DVC. Moreover, policymakers should continuously improve digital rural facilities, prioritize supporting the development of AgI, and enrich and improve agricultural information services to accelerate the increase in SICLU.
