Off-farm employment and agricultural land use efficiency in China

Abstract

The non-agricultural employment transfer of the rural labor force has fundamentally changed the labor input in China in recent decades. A good understanding of how the off-farm employment of rural laborers affects agricultural land use in China is needed. We use the Driscoll and Kraay standard errors fixed effects model to investigate the relationship between rural laborers' off-farm employment and agricultural land use efficiency based on a panel data of 1,961 counties in China. We find that the distribution of county-level agricultural land use efficiency is heavily skewed to the right, with many counties below the national average efficiency level. We also identify a robust U-shaped relationship between off-farm employment and the change in agricultural land use efficiency, indicating that the substitution effect of capital and technology for rural labor has changed from weak to strong. The findings have important policy implications for the joint reform of the household registration (hukou) system and the rural land use system (i.e., the Three Rights Separation Reform) in China. Using the criteria derived from empirical analysis, we also perform content analysis to assess 20 rural land use policies implemented between 2014 and 2020. We find that these documents covered the three important areas to improve rural land use efficiency, that is, rural-urban mobility, rural land rights market development, and rural land rights protection. Although a synergy among the three areas has not yet been achieved, the central government has already put in place policies to enable and support coordinated actions in the three areas. The lessons learned from China also serve as a helpful reference for addressing the challenge of rural labor loss in other developing countries.

New Round of Collective Forest Rights Reform, Forestland Transfer and Household Production Efficiency

“…The age of male or female farmers was not found to be significant in a study of Koirala et al [44]. Zhao et al [47] identified a robust U-shaped relationship between off-farm labor and agricultural land use efficiency, indicating that the relationship of non-agricultural income and agricultural land use efficiency was significantly positive after the turning point. When Jelsma et al [43] assessed the implementation of Good Agricultural Practices among different types of independent oil palm smallholders in Riau, Indonesia, they found that the wealthy farmers may not be able to implement better agricultural practices.…”

Labor Structure, Land Fragmentation, and Land-Use Efficiency from the Perspective of Mediation Effect: Based on a Survey of Garlic Growers in Lanling, China

“…[58]. However, it did not change the county-level agricultural land-use efficiency being lower than the national average efficiency level [59]. From the above, it can be seen that changes in the labor force structure have a certain impact on land fragmentation.…”

Coordinated Relationship between Compactness and Land-Use Efficiency in Shrinking Cities: A Case Study of Northeast China

“…Previous studies gradually enriched and improved the methods of measuring land-use efficiency. Using the entropy value method, data envelopment, and consequent frontier analysis, researchers have thoroughly studied the efficiency of urban, industrial, agricultural, and development zone land [22][23][24][25][26][27][28]. Furthermore, more attention has been paid to interaction mechanisms of land-use efficiency and systems such as urban spatial development, economic development, and urban ecology.…”
