Heterogeneous land development opportunities induced by spatial regulation produce different advantages in areas, which undoubtedly differentiates farmers’ employment. The aim of this study was to quantitatively examine its impact. We selected Moshui Lake City Park (urban development planning area), Sino-French Eco-City (industrial development planning area), and Chenhu International Wetland (ecological protection planning area) as its principal research areas. These regions are all located in Wuhan city, Hubei province, China. After obtaining 907 valid responses from rural households, the Tobit model was adopted to identify the impact of land development opportunities on farmers’ nonfarm employment. The results show that, first, industrial development opportunity (IDO) and urban development opportunity (UDO) provide more job security than the reference group, which is ecological development opportunity (EDO), with the estimated coefficients of IDO and UDO being 0.325 and 0.944, respectively. However, a negative correlation was found between UDO and farmers’ employment selection and income. Second, heterogeneity analysis reveals that the promotion effect of land development opportunities on farmers’ employment is more significant for low- and middle-income, low-quantity, and high-quality households. Finally, further analysis shows that IDO can promote employment for all age groups, but UDO inhibits the elderly labor force from getting employed. These findings provide evidence-based insights which can enable the government to formulate land value-added distribution systems that promote balanced development between regions and stakeholders.

While land development opportunities stemming from planning regulations demonstrably influence rural household income, quantitative evidence quantifying these effects remains limited. Measuring and decomposing these effects can empirically support territorial spatial planning policies aimed at alleviating associated regional development imbalances and advancing sustainable rural development. This study selects Wuhan’s Sino-French Eco-City (urban development zone) and Xiaosi Township (wetland conservation zone) as typical zones. Based on 573 randomly sampled rural households, we explore the effects of land development opportunities on rural household incomes and find that: (1) Land development opportunities for non-agricultural conversion in the urban development zone significantly increase rural households’ total income, wage income, though their corresponding contribution rates are limited. Endogenously accumulated endowments such as human capital and economic status dominate the formation of such income gaps. (2) Planning-induced land development opportunities yield coefficients of 1.0442 for local employment income and −0.4567 for agricultural business income, with both statistically significant at the 1% significance level. Decomposition results show their respective contribution rates of 70.68% and 86.77%, demonstrating that such opportunities primarily account for cross-regional rural household income gaps. (3) Whereas non-agricultural land development opportunities narrow disparities in households’ local employment income, they raise inequality in rural households’ migrant employment, business, property and transfer income. These growth and equality-enhancing effects on local wage income are particularly pronounced for households possessing high-quantity but low-quality human capital. This study recommends supporting protected zones via farmer vocational training, expanded rural public service expenditure, and a benefit-sharing mechanism that channels land development gains to ecological and agricultural regions to strengthen households’ endogenous development capacity.

The withdrawal of rural households from contracted farmland optimizes land resource allocation, aligning with urbanization and agricultural modernization goals, and supports agricultural transformation and urban–rural integration. Utilizing survey data from 1478 rural households in Shanghai and Wuhan suburbs, this study employs ordered Probit models and mediation effect tests to examine how urban social security influences farmland withdrawal and the role of pension income. Results indicate that within the context of new urbanization, 56.90% of rural households exhibit a social security participation rate exceeding 50%, with urban social security enrollment significantly facilitating the withdrawal of contracted farmland by suburban rural households. Specifically, a one-unit rise in the proportion of insured individuals escalates the likelihood of permanent farmland withdrawal by 25%. Among these, pension income plays a positive mediating role in the process of urban social security influencing farmers’ withdrawal from farmland. Participation in urban social security enhances farmers’ pension income levels, thereby strengthening their farmland withdrawal degree. Consequently, to effectively advance the mechanism for rural farmland withdrawal, social security emerges as a fundamental pillar. This study furnishes empirical backing for the “substituting land security with social security” proposition and offers crucial insights for enhancing rural land withdrawal policies.
