Abstract ：
With growing concern toward sustainable urban regeneration (UR) and the inability of existing UR policy instrument frequency studies to distinguish the blurring content in policies, a systematic framework quantitatively analyzing the temporal evolution of the content of UR policies is necessary. This paper considers localized modes, incorporates methods from multidimensions of UR, beyond merely the frequency of policy instruments, and proposes the Supply-Environment-Demand-Mode-Method framework. Dynamic topic modeling was utilized to reveal the thematic evolution quantitatively based on 427 UR policy documents in Shanghai. The results reveal that: (1) the municipal governments concentrate on environment-side instruments, especially nonfinancial ones; (2) policies of demolition, conservation, and renovation overlap throughout history rather than separately distributed; (3) quantitative evidence is provided that ecology and culture are less prioritized in UR compared to other dimensions. This paper provides a data-support holistic view of UR evolution in Shanghai for urban planners and other practitioners; three channels to improve UR practice are also proposed. This research highlights more possibilities to study UR from perspectives of policy implementation, policy process, and cross-disciplinary arena in the future.

Abstract ：
Land resources are crucial yet limited inputs in economic activities, with significant implications for both economic development and public sector behaviour. This study investigates how land resource supply affects local government actions, using the place-biased land supply policy (PBLP) introduced in 2004 as a quasi-natural experiment. Through a propensity score matching and difference-in-differences (PSM-DID) approach, this study finds that cities facing land supply restrictions under PBLP experienced slower GDP growth alongside higher pollutant emissions. These effects remain robust across alternative variable measures, accounting for other policies, and varying matching techniques. The slowdown in economic growth is primarily driven by reduced fixed assets and foreign investment, prompting local governments to relax environmental regulations to boost short-term growth. These findings highlight the unintended consequences of administrative land policies on social welfare, revealing the complex dynamics between land supply, government behaviour, and socio-economic outcomes.

Abstract ：
This study examines the impact of China's industrial land approval reform (ILAR) on the provision of subnational services. Utilizing the 2011 pilot reform policy approved by the State Council, we utilize a staggered Difference-in-Differences (DID) method to determine the reform's impact on local economic growth and environmental protection. The findings reveal that the reform enhances local economic development and decreases pollution levels. Additionally, the reform significantly decreases land resource misallocation in pilot cities, enhancing productivity. We also find that local governments allocate more land to the tertiary sector through this reform, achieving industrial upgrading. The optimization effects are more pronounced in cities with higher fiscal pressure. Based on these findings, we recommend that policymakers sustain decentralization efforts and consider further incentives for cities under fiscal stress. We fill a gap in the literature by linking land use regulation with subnational service provision, contributing to the understanding of the socioeconomic benefits of decentralization and local government service levels.

Abstract ：
The driving mechanism of urban-rural integration development (URID) is a complex and organic operation system that continuously evolves and plays an orderly role. In order to expand the related theoretical system on the driving mechanism of URID and guide the URID in the Yangtze River Delta, this study constructed a system dynamics model of the driving mechanism of URID in the Yangtze River Delta. The dynamic evolution characteristics of different dimensions and the comprehensive level of URID in the Yangtze River Delta over time under four types of scenarios (including the benchmark scenario and scenarios of three different types of driving factors: Endogenous factor, exogenous factor, and basic factor) were simulated and analyzed. Key issues in the driving mechanism of URID were also discussed. The results show that: 1) The overall trend of the levels of different dimensions and the comprehensive level of URID in the Yangtze River Delta are positive under the benchmark scenario. 2) The three types of driving factors have different driving paths to URID, but they can make up for the lack of driving force in different dimensions of URID of others. 3) The driving effect of the exogenous factor and basic factor on URID in the Yangtze River Delta is obviously weaker than that of the endogenous factor. © 2024, Editorial office of PROGRESS IN GEOGRAPHY.

Abstract ：
Industrial structure upgrading (ISU) is a crucial step towards achieving low-carbon development for China. This paper aims to assess the influence of ISU on agricultural carbon emissions (ACE), and unveil its underlying mechanism. By employing the Spatial Durbin Model (SDM), the findings demonstrate that ISU has a significant inhibitory effect on ACE, while displaying a promoting effect on ACE of neighbouring regions. Additionally, transportation infrastructure and population density have an intermediary effect in the relationship. When using ISU and level of economic development as a threshold variable, ISU exhibits a positive impact before the threshold, and a negative impact after the threshold. Furthermore, this study reveals regional heterogeneity, that is, ISU has varying impacts on ACE in eastern, central and western China.

Abstract ：
The transition to a green, sustainable economy is largely reliant on corporate investment in the realm of environmental protection. Utilizing the adoption of the third phase of the Golden Tax Project (GTPIII) in China as a quasi-natural experiment, this paper examines how corporate environmental investment changes in response to greater tax enforcement. Our results reveal that tougher tax enforcement significantly lowers corporate environmental investment. Such an effect is stronger for firms faced by high financial constraints and those operating in non-heavy-polluting industries. Moreover, the mechanism analysis indicates that the higher tax burden induced by greater tax enforcement is the potential channel. Overall, this paper shows that stricter tax enforcement could potentially result in adverse spillover effects on corporate environmental investment, which warrants attention in tax collection practices.

Abstract ：
The critical role of high-quality urban development and scientific land use in leveraging big data for air quality enhancement is paramount. The application of machine learning for causal inferences in research related to big data development and air pollution presents considerable potential. This study employs a double machine learning model to explore the impact of big data development on the PM2.5 concentration in 277 prefecture-level cities across China. This analysis is grounded in the quasi-natural experiment named the National Big Data Comprehensive Pilot Zone. The findings reveal a significant inverse relationship between big data development and PM2.5 levels, with a correlation coefficient of -0.0149, a result consistently supported by various robustness checks. Further mechanism analyses elucidate that big data development markedly diminishes PM2.5 levels through the avenues of enhanced urban development and land use planning. The examination of heterogeneity underscores big data's suppressive effect on PM2.5 levels across central, eastern, and western regions, as well as in both resource-dependent and non-resource-dependent cities, albeit with varying degrees of significance. This study offers policy recommendations for the formulation and execution of big data policies, emphasizing the importance of acknowledging local variances and the structural nuances of urban economies.

Abstract ：
The imbalance of rural human-land relationships has become a notable problem in China's urbanization process. The dual urban-rural system is widely regarded as the crucial factor contributing to this problem in China. Although the significance of institutional forces has been substantially recognized, the rural homestead system seems to be generally under-evaluated in this issue. Most of the previous literature focuses on the dual household registration system, while the effects and the detailed mechanisms of the rural homestead system on human-land relationships lack depth in research. The objective of this research is to help fill this gap in the literature on the complex effects and the detailed mechanisms of the rural homestead system on rural human-land relationships. In view of this, this paper establishes a conceptual framework on the basis of land function theory and public domain of property rights theory and proposes two mechanism hypotheses: one is the land attachment mechanism of farmers' rights and interests (LAM), the other is the land finance preference mechanism of local governments (LFPM). Then, this article examines them empirically using the panel model with the data of 41 cities from 2010 to 2021 in the Yangtze River Delta of China. The main conclusions are as follows: (1) LAM promotes the imbalance of rural human-land relationships due to the attachment of farmer's social security rights and property expectant interests to the rural homesteads; (2) LFPM drives the imbalance of rural human-land relationships, owing to both the preference of land transfer revenue and the exclusion of rural migrants' citizenship financial cost on local governments; (3) the moderating effects suggest that LFPM can strengthen the effect of LAM, and the spatial Durbin model results show that both LAM and LFPM have spatial spillover effects. It is hoped that the findings will provide a reference for deepening the rural homestead system reform.

Abstract ：
This paper examines the impacts of government-market relation (measured by the degree of marketization) on the link between financial deepening and income growth of rural residents. Using macro panel data covering a period from 2010 to 2021 across 31 provincial administrative regions in China, we create an interaction variable that captures the interplay between financial deepening and the degree of marketization. Employing a fixed effects model and a dynamic panel regression model, we derive three robust findings from the regression analysis: (1) the higher the degree of marketization, the stronger the promotion effect of financial deepening on the growth of rural residents' income, with a one-year lag effect; (2) the higher the degree of marketization, the stronger the promotion effect of financial deepening on the wage income of rural residents, with a one-year lag effect; (3) the higher marketization fails to create the promotion effects of financial deepening on the net business income and net property income of rural residents. These results suggest that financial deepening aimed at raising rural residents' incomes in provinces, where China's marketization has slowed down, stagnated, or retrogressed, will have difficulty reaching its goals, and that some of the financial and economic problems affecting the growth of rural residents' business and property incomes remain unresolved.
