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 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 ：
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 ：
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 ：
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。
