After nearly forty years of development, China’s land consolidation policies (CLCP) have become an important tool for promoting rural revitalization and sustainable development. However, as a major land management policy, there is still a lack of quantitative evaluation research on its text. This paper establishes an evaluation system for CLCP using text analysis and the PMC-Index model. Based on a reasonable definition of the connotation of land consolidation, this paper collects 313 related policies issued by China’s central government from 1982 to 2022, using text analysis to sort out the characteristics of issuance time, policy types, issuing institutions, and cooperation networks. By combining the outcomes of text mining with the previous research results to set evaluation indicators for the PMC-Index model, it distinguishes between comprehensive policies and specialized policies and separately evaluates them. Then, the PMC-Surface is established to clearly display the calculation results. The results show that the evaluation scores of comprehensive policies and specialized policies showed an upward trend over time. This indicates that the content of CLCP is constantly being enriched and expanded. The evaluation scores for different dimensions of comprehensive policies are relatively balanced, whereas there are significant differences in the evaluation scores of various dimensions of specialized policies. Both comprehensive policies and specialized policies have weaknesses in policy functions, incentives and constraints, and implementation guarantees, so improvements may be needed in these areas in the future. This study provides valuable insights into the advantages and disadvantages of a single land consolidation policy in China.

The spatial mismatch between affordable housing neighborhoods and public services/facilities significantly reduces the well-being of low-income dwellers, which has risen to a typical issue of spatial injustice. Previous studies on accessibility evaluation most focus on a single type of service, lacking empirical studies exploring the integrated spatial accessibility of multiple services for low-income residents. Taking Harbin City in northeast China as an example, this study assessed the spatial accessibility of transit, education, healthcare, shopping, and recreation facilities for affordable housing neighborhoods, using the Gaussian-based 2SFCA method. The pattern of accessibility for each type of facility in Harbin showed obvious spatial differentiation between the urban core and the city periphery, for both affordable housing neighborhoods and other neighborhoods. The sample household survey indicated that low-income households who were generally characterized as elderly, less-educated, under-employed or unemployed had extremely restricted and passive residence choices. In comparison to non-low-income households, the spatial accessibility of higher-level facilities for low-income households was relatively poorer. Particularly, affordable housing neighborhoods had much lower accessibility of subway stations, though more than 97% of low-income respondents living in affordable housing neighborhoods chose to solve the daily trip demand by taking a bus or the subway. With respect to equity-oriented urban planning, more importance should be attached to the spatial accessibility of public services and facilities when planning affordable housing projects for low-income households.

The health of our planet’s ecosystems is deeply linked to how we manage land resources

Previous studies suggest that market forces and the strategic behavior of local governments regarding land development jointly contribute to rapid urban expansion in China. In underdeveloped small cities in Western China, the market is weak, and local governments lack the conditions required to promote land-centered urbanization. Surprisingly, these cities have experienced an expansion of urban space faster than the national average. This study presents a significant funding model of urban land development within the framework of the project system. Within this model, central and provincial governments are key providers of land development funds. Local governments design, apply for, package, and implement land development projects. Private developers cooperate with local governments rather than functioning as real initiators of and investors in land development projects. The findings provide new and supplementary evidence about how rapid urban expansion occurs in China, particularly in underdeveloped areas.

Neighbourhood outcomes of migration have drawn considerable scholarly attention. Previous studies consider neighbourhood trust an indicator of social integration or social resources, revealing inconclusive findings regarding the effects of migration. Unlike previous studies, we view neighbourhood trust as a lifestyle feature. Combining urbanism theory and a typology of trust, we argue that migration causes a reduction in migrants’ neighbourhood trust through the assimilation of the urbanism lifestyle. We provide nationwide empirical evidence of the causal relationship between migration and neighbourhood trust and reveal the underlying mechanism. Our study identifies this relationship in urban China by applying a difference-in-differences empirical strategy and using the China Family Panel Survey. The results show that migration lowers neighbourhood trust levels by 0.473 from a sample mean of 6.692. We find that the declining effect is greater for rural–urban migrants than for within-urban migrants, and it is greater for rural–urban migrants who acquire urban hukou than for those who do not. We also show that rural–urban migration leads to an increase in trust in strangers. Together, these results support our hypothesis that the assimilation of the urbanism lifestyle is a critical mechanism through which migration undermines neighbourhood trust.
