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 :
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 :
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 :
This paper examines the existence and mechanism of China's liquidity trap. First, a broad money supply model is reconstructed to evaluate the effectiveness of monetary policy. Based on the observed data from 1997 to 2022 and first-order difference regression results, we find that: The relationship between the monetary base and broad money exhibits two distinct stages, with 2008 as a delineating point. Pre-2008, the money creation multiplier is significant; post-2008, it becomes insignificant. Second, by examining the asset-side and liability-side gaps of the financial system, we have identified two liquidity traps. The first occurs between 2015 and 2019, caused by funds idling within the financial system. The second occurs in 2020- and is caused by recessionary expectations. Monetary policy flexibility is waning, compelling strategic decisions for Chinese government and central bank.

Abstract :
厘清乡村振兴对黄河流域农业碳排放的影响, 对于黄河流域高质量发展和农业低碳发展均具有重要意义。本文基于黄河流域2001—2021年间88个地级市的面板数据, 采用空间计量模型和门槛回归模型分析乡村振兴对黄河流域农业碳排放的影响和空间溢出效应, 并对二者的非线性关系和区域异质性进行了分析。结果显示, 乡村振兴对农业碳排放具有显著的促进作用, 同时表现出显著的负向空间溢出效应, 且乡村振兴对农业碳排放的空间溢出效应大于直接效应, 此外产业结构和城镇化对农业碳排放具有负向影响, 种植规模、化肥施用强度和农业经济发展对农业碳排放呈正向影响。农业技术进步在乡村振兴对农业碳排放的影响中具有门槛效应, 当农业技术进步越过门槛值时, 乡村振兴对农业碳排放的影响由正转负。从异质性角度来看, 在粮食主产区, 乡村振兴对农业碳排放表现为抑制作用, 而在非粮食主产区, 乡村振兴对农业碳排放表现为促进作用。就地理区位而言, 乡村振兴对黄河中游和下游区域农业碳排放表现为抑制作用, 对黄河上游区域表现为促进作用。因此, 应重视农业碳排放的区域差异, 强化农业技术进步在乡村振兴过程中的减排作用, 并因地制宜采取措施推动农业碳减排, 进而实现黄河流域农业绿色低碳发展。

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.

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.
