With ensuring food security becoming a priority for the Chinese government, the prevalence of off-farm employment (OE) may cast a shadow on agricultural productivity. Based on the data of the China Family Panel Studies in 2018, the Tobit model and threshold effect model have been applied to investigate the impact of off-farm employment on agricultural productivity efficiency (APE), measured by data envelopment analysis (DEA). The result has shown that: (1) OE contributes to a low level of APE. (2) Both self-employed off-farm employment (SOE) and wage-based off-farm employment (WOE) result in lower APE levels when endogenous issues are addressed. However, SOE had a greater negative impact on APE than WOE. (3) There exists a threshold for OE associated with a lower level of APE, indicating that the negative effect of OE on APE disappears when the degree of OE is high enough, SOE has a lower threshold than WOE. The study findings have implications for improving agricultural production efficiency in the context of large-scale off-farm employment of Chinese farmers.

The rapid advancement of digital communication and information technologies has significantly influenced rural household income and income inequality. Based on a sample of 2216 farmers from the China Family Panel Studies (CFPS), this analysis combines Ordinary Least Squares (OLS) regression with Conditional Mixed Process (CMP) estimation to account for endogeneity, evaluating how internet adoption affects both income diversification and inequality patterns among Chinese farmers. The findings reveal three key insights: First, internet use significantly increases farmers’ household income while reducing overall income inequality. Second, the positive impact of internet use on total income is primarily driven by increases in wage and operating income, while the reduction in income inequality is associated with a more equitable distribution of these income sources. Third, human capital plays a moderating role, with high-human-capital farmers benefiting more from internet use in terms of income growth and inequality reduction. Based on these findings, this study suggests that policymakers should promote internet adoption to enhance farmers’ incomes and address income inequality, while paying attention to the varying effects across different human capital groups. These insights provide valuable policy implications for achieving common prosperity in developing countries and regions.

Currently, China is facing the problems of chaotic governance of end-use agricultural water conservancy facilities and a serious waste of agricultural water. To address the above issues, China launched a pilot policy of reforming the property rights of agricultural water facilities in 2014. In this study, we obtained data from 328 farm households through a microscopic study of the pilot property rights reform in Yunnan Province. We found that the reform has resulted in two typical property rights models: “Multiple cooperative governance” and “Private contract governance”. The impact of the reform on the maintenance quality of irrigation facilities and farmers’ water-saving technology adoption behavior was empirically analyzed using the Oprobit and IV-Oprobit methods. The study found that: (1) the property rights reform significantly improved the quality of maintenance of facilities while promoting farmers’ water-saving technology adoption behavior. (2) Heterogeneity analysis revealed that the degree of non-farming of farmers had a negative moderating effect on the quality of facility maintenance and a positive moderating effect on the adoption of water-saving technologies, and the physical health of farmers had a negative moderating effect on the quality of facility maintenance. (3) There was no significant difference in the quality of facility maintenance between the “Private contract model” and the “Multiple cooperative governance model”, but the former had higher water supply capacity; in addition, farmers under the “Multiple cooperative governance model” mainly used drip irrigation technology, whereas farmers under the “Private contract governance model” mainly used sprinkler irrigation technology. The findings of this study provide Chinese experience in promoting the governance of agricultural water facilities and promoting the water-saving behavior of farmers.

China is implementing a pilot project to reform the property rights of farmland water facilities to solve the serious problems of chaotic end-of-pipe governance and inefficient irrigation from farmers. Based on microscopic research data of farm households in a typical pilot in Lu Liang County, Yunnan Province, in China, this study uses the Tobit model, and SEM was used to explore the impact of property rights reform on the irrigation efficiency of farmers and the potential mechanism paths. We further analyzed the differences in governance logic and irrigation efficiency between the two property rights models of “multiple cooperative governance” and “private contract governance” formed after the reform. The findings are as follows: (1) Compared with nonreformed areas, reformed areas have a higher promotion of adoption of water-saving technologies and a better quality of facility maintenance, which significantly contributes to irrigation efficiency, but farmers’ perception of water scarcity negatively affects irrigation efficiency; (2) there are differences between the “multiple cooperative governance model” and “private contract governance model” in terms of the mechanism paths to improve irrigation efficiency, resulting in different focuses between the two models, in which the former one has better irrigation efficiency while cutting off some of the farmers’ benefits and the latter benefits more farmers while losing some of the irrigation efficiency. Finally, this study recommends that China should continue to promote the reform of farmland water property rights while focusing on promoting water conservation technologies, improving the quality of facility maintenance and facility water supply capacity, enhancing farmers’ awareness of water scarcity, and implementing a more water-efficient “multiple cooperative governance model”. The results of this study provide a model with Chinese characteristics for developing property rights policies and governance models for farmland water facilities in developing countries.
