The rapid urbanization in China has had a huge impact on land use and the scarcity of land resources has become a constraint for sustainable urban development. As urban land is an indispensable material basis in economic development, measuring its use efficiency and adopting effective policies to improve urban land use efficiency (ULUE) are important links in maintaining sustainable economic growth. By establishing a comprehensive ULUE evaluation index system that emphasizes on incorporating the natural resources input and the undesirable output, ULUE from 2010 to 2016 was calculated based on super efficiency SBM model, and its potential influencing factors were explored using a spatial econometric model. The results show that: (1) temporally, the overall ULUE in China is upward growing, and the gap among regions is becoming gradually convergent. (2) Spatially, the ULUE of Chinese cities are positively correlated. (3) Economic agglomeration and industrial structure significantly improve ULUE in China, but the intensity of energy consumption has a negative impact on ULUE. We suggest that: (1) differentiated industrial development strategies should be formulated; (2) the economic growth pattern should be changed from energy-consuming to energy-saving; (3) priority should be given to innovation on science and education, so as to increase in clean energy input and cleaner production.

The research question for this study is estimating the public’s willingness to pay for the public goods generated by farmland, and exploring respondents’ heterogeneity in their preferences for these goods. The approach used is a choice experiment, using respondents from the city of Wuhan, China. Six attributes representing public good values (farmland area, farmland fertility, water quality, air quality, species richness, and recreational value) and the level of private cost are selected in this study. A heteroscedastic conditional logit model is used to analyze the respondents’ willingness to pay for improvements in these public goods, accounting for systematic heterogeneity in public preferences. The results show the public are willing to pay to preserve the non-market values generated by farmland, with air quality valued most and followed by farmland fertility, farmland area, water quality, species richness and recreational value. In addition, respondents with higher income, and who are aware of the non-market values of farmland and have a willingness to pay for it have a smaller error variance, i.e., these respondents are more consistent in their choices. This study may help decision makers improving more differentiated farmland protection policies.

Urban village redevelopment has multidimensional impacts on resettled households. These impacts can reflect the sustainability of urban village redevelopment. This study empirically compares the gains and losses of the welfare in economic conditions, living conditions, natural environment, psychological conditions, and social security in bottom-up and top-down urban village redevelopment cases in Wuhan, China. The results show that a bottom-up redevelopment mode with participative residents caused negative effects in economic welfare but positive effects on living conditions, natural environment, and psychological condition, thus promoting higher comprehensive welfare and satisfaction. Top-down redevelopment led by the government provides villagers with shared dividends through collective economic reform and thus, contributes to gains in economic conditions and social security. However, top-down redevelopment with less participation of residents leads to welfare losses in living conditions, natural environment, and psychological conditions, which results in lower welfare and satisfaction levels overall. Therefore, a middle-out redevelopment mode with a combination of government efforts and public participation are proposed as a solution for sustainable urban redevelopment.

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.

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.
