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 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 ：
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 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 ：
The problems that exist in China's agricultural operations are not only on a small scale; more seriously, there are also problems of land fragmentation and the mismatch of human and land resources. Land transfer is expected to be a tool for solving these problems. The land transfer market development is slow, leaving farmers facing serious information asymmetry. On the back of the information explosion brought about by information technology represented by the Internet, exploring the impact of Internet use on land transfer can provide ideas to improve the solution of land problems. Based on the cost theory analysis framework of new institutional economics, this paper empirically examines the impact of Internet use on farmers' land transfer behavior. The results of the study show that Internet use can significantly increase the probability and scale of household land transfer by reducing the fixed and variable costs of transactions. This conclusion still holds after using instrumental variables to address endogeneity. The impact of Internet use on land transfer is heterogeneous, with the younger, more educated, and higher-income household heads tending to participate in the land transfer market on a larger land transfer scale. Therefore, rural Internet infrastructure should be further improved to alleviate information asymmetry in the land transfer market, further strengthen the training of Internet use skills of farmers, stimulate the enthusiasm of farmers to participate in the land transfer market, further increase farmers' income, enhance the elasticity of farmers' response to the use of the Internet to reduce transaction costs, and promote land transfer.

Abstract ：
As a vital guarantee of food security for many countries, international food trade has been threatened by volatile international political ties in recent years. However, the existing literature lacks empirical evidence on the relationship between political ties and food export stability. Therefore, this article examines the impact of political ties on food export stability using United Nations General Assembly (UNGA) voting data and export data on food products from 2010 to 2018. The chosen timeframe ensures the exclusion of potential influences from both the financial crisis and the COVID-19 pandemic, enhancing the robustness of the findings. The test results show that the deterioration of political ties can reduce food export stability: the higher the voting dissimilarity of the trading partners in the UNGA, the less stable food exports. Mechanism analysis suggests that political ties can impede food export stability by increasing tariff and non-tariff barriers. The analysis of heterogeneity indicates that the advancement of urbanization in importing countries intensifies the adverse effects of political ties on food export stability. However, this negative impact is less pronounced when importing countries have more allocation and higher productivity regarding land resources such as cultivated land and forests. This article adds to the literature on the relationship between political ties, trade, land resource optimization, and food security. The findings of this study highlight the importance of land resources with respect to reducing the risk of food trade instability in the context of volatile international politics.

Abstract ：
Improving urban land use efficiency is a feasible way to realize sustainable development and alleviate urban land pressure on the city. The main purpose of this article is to measure the urban land use efficiency of the Yangtze River Economic Belt, and explore its evolutionary trends and influencing factors, so as to provide references for policy formulation to promote efficient land use and sustainable development. Therefore, we calculated the value of urban land use efficiency in the Yangtze River economic belt from 2004 to 2019, based on the super efficiency SBM model, including unexpected output. Further, we analyzed the spatial-temporal evolution, and spatial correlation and its influencing factors. The main results are as follows: Firstly, urban land use efficiency in the Yangtze River economic belt continues to improve as a whole, but it is higher in the east and lower in the west. In the kernel density evolution map, the development trend is steep at first and then slows, and the gap tends to decrease. Secondly, the spatial correlation of urban land use efficiency in the Yangtze River economic belt increases year by year, showing a positive correlation overall. The high-high agglomeration shifts to the east, low-low agglomeration shifts to the west, and low-high and high-low agglomeration show scattered distribution. The hot and cold spots are distributed regionally and have a diffusion trend. Thirdly, the results of the spatial Dubbin model show that the urbanization level, government expenditure and industrial instruction transformation can promote the improvement of urban land use efficiency, and people density and land use scale can inhibit its improvement. Additionally, there is remarkable heterogeneity in the effect of these influencing factors. On the whole, the effect of non-resource-based cities is better, and it is more so in the cities of the eastern region.

Abstract ：
The measurement of public service provision (PSP) performance and identification of its influencing variables are of great importance for the government to efficiently utilize public resources and provide more effective public services. However, existing studies have mainly focused on the efficiency to provide public services and ignored the effectiveness to improve public subjective well-being. To fill this gap, this study constructs a two-stage PSP conceptual model from the perspective of service production and consumption and develops a corresponding PSP performance evaluation indicator system to evaluate PSP efficiency, effectiveness, and comprehensive perfor-mance. The PSP performances of 35 major cities in China during 2011-2018 are calculated using the super efficiency network slack-based measure model. Moreover, the influencing factors of these performances are identified through the truncated regression model. Results indicate that the comprehensive performance of these cities is relatively low and shows a trend of decrease that is predominantly caused by provision efficiency. Owing to the absolute advantage in effectiveness and the catch-up effect in efficiency, cities in the western region perform the best in comprehensive performance, followed by the eastern region and then the central region. In addition, only seven cities achieve a balance between efficiency and effectiveness. Factors from economy, so-ciety, government, and public aspects have different impacts on PSP performances. On the basis of these findings, several policy suggestions are proposed. This study proposes a relatively comprehensive and accurate mea-surement framework of PSP performance that considers both efficiency and effectiveness and can help policy -makers implement appropriate strategies promoting PSP in an efficient, effective, and sustainable manner.
