Enhancing farmers’ behaviors toward cultivated land quality protection is a crucial support in achieving sustainable agricultural development and the national food security strategy. This study aims to investigate the impact of land transfer-in on farmers’ behaviors regarding cultivated land quality protection, explore the underlying mechanisms, and analyze group heterogeneity. To achieve this, the study empirically estimates the impact of land transfer-in on farmers’ behaviors in protecting cultivated land quality using micro-survey data from 743 households in Hubei Province, while addressing endogeneity and conducting robustness checks. The study further explores the mechanisms and heterogeneity of the effects of land transfer-in on farmers’ cultivated land quality protection behaviors. The results reveal that (1) land transfer-in significantly increases the likelihood of farmers taking actual actions to protect cultivated land quality and enhances their awareness, thereby promoting protective behaviors; (2) land transfer-in facilitates these protective behaviors mainly through income incentives and social network interactions, while rental constraints may have a suppressive effect; (3) full-time farmers, those with higher agricultural literacy, those who access agricultural knowledge online, and those affected by natural disasters are more likely to engage in proactive land quality protection behaviors after land transfer-in.

Improving the quality of rural human settlements is a key objective in China’s rural revitalization strategy. The purpose of this study is to construct and evaluate the quality of rural human settlements in China from a micro perspective. To achieve this objective, the main tasks include constructing an evaluation system for rural human settlement quality from a micro perspective; measuring the overall and dimension-specific quality levels of rural human settlements using the entropy method based on data from 108 villages in Shandong, Jilin, and Hubei provinces; and further analyzing the influencing factors of rural human settlement quality, focusing on village per capita income, resident population, fire incidents, and agricultural input prices. The findings reveal the following: (1) The overall quality of rural human settlements in Hubei, Shandong, and Jilin is at a moderate-to-low level, with no significant differences among provinces. (2) Among the various dimensions of rural human settlement quality, economic development and public services score higher, whereas living facilities and sanitary conditions score relatively lower, reflecting the inertia of long-term resource allocation and the lagged effects of emerging projects. (3) An increase in village per capita net income and the resident population significantly improves rural human settlement quality, whereas incidents such as village fires and sharp increases in agricultural input prices significantly reduce it. This study provides empirical insights into the mechanisms affecting rural human settlement quality from a micro perspective and offers policy implications for its targeted improvement.
