Overseas industrial parks (OIPs) offer platforms to host countries for foreign and domestic company agglomeration in key industries to promote economic development. This study examined 123 Chinese OIPs in “Belt and Road Initiative” (BRI) countries to study the productive effects in the host countries for a sample period of 2010 to 2018. It was found that Chinese OIPs, especially high-tech, logistics, multi-sector and state-owned ones, significantly increased local productive capabilities through trade promotion and employment generation. Host countries with higher level of governance, business environment, finance, transport, and bilateral investment protection had more pronounced effects. This paper provides evidence for China's industrial park spillovers and insights into the internationalization performances of developing economies.

We assess the impact of China's bilateral political relations with three main trading partners—the US, Germany, and the UK—on current account balances and exchange rates, over the 1960Q1–2022Q4 period. Relying on the lag-augmented VAR approach with time-varying Granger causality tests, we find that political relationships with China strongly matter in explaining the dynamics of current accounts and exchange rates, supporting the “trade follows the flag” view. Such relationships cause the evolution of the exchange rate (except in the UK) and the current account; these causal links being time-varying for the US and the UK and robust over the entire period for Germany. These findings suggest that policymakers should account for bilateral political relationships to understand the global macroeconomic consequences of political tensions.
我们评估了 1960Q1-2022Q4 期间中国与三个主要贸易伙伴(美国、德国和英国)的双边政治关系对经常账户余额和汇率的影响。利用时变格兰杰因果检验的滞后增量 VAR 方法,我们发现,与中国的政治关系在解释经常账户和汇率的动态方面具有重要作用,支持了 "贸易随国旗走 "的观点。这种关系导致了汇率(英国除外)和经常账户的演变;这些因果关系在美国和英国是时变的,而在德国则在整个时期内是稳健的。这些研究结果表明,决策者应考虑双边政治关系,以了解政治紧张局势对全球宏观经济的影响。

Exorbitant land prices have been a significant constraint on firm growth; however, few studies have explored their effect on firms' global value chain (GVC) positions. By treating the 2007 minimum price policy for industrial land as a quasi-natural experiment, this study estimates the impact of land price regulations on firms' GVC positions. Using a difference-in-differences method with continuous treatment intensity, we find that industrial land price regulation has a remarkably negative effect on firms' GVC positions. This effect is primarily observed in small- and medium-sized enterprises and private enterprises. The mechanism analysis suggests that industrial land price regulation has significantly increased the cost of land purchases by firms, squeezing their investment in innovation and reducing the quality of intermediate inputs, thereby degrading their position in GVCs.

The carbon reduction effects of climate mitigation have received much attention, but less attention has been paid to the co-benefits of climate mitigation such as such as air pollution reduction and related health impacts. This oversight may have led to an underestimation of the broader welfare effects of climate mitigation and thus hindering its progress in implementation. This paper investigates the co-benefits of climate mitigation through focusing on the pollution reduction effects of the implementation of the clean development mechanism (CDM), which is an important climate mitigation mechanism to enhance north-south climate cooperation. Using a unique firm-level dataset with data on China's CDM projects from 1998 to 2012, we show that the CDM implementation reduced sulfur dioxide emissions. Mechanism analyses show that the CDM implementation alleviated firms' financing constraints and promoted fossil energy savings, thereby reducing emissions of air pollutants that usually coexist with greenhouse gases in burning fossil fuels. We also find that the CDM didn't bring about the expected technological progress. These results highlight environmental co-benefits of climate mitigation and provide important implications for international climate cooperation

This study evaluates the policy objectives and efficacy of government venture capital funds (GVCs) on the performance of invested entrepreneurial ventures. Analyzing data from China on GVCs, private venture capital funds (PVCs), and foreign venture capital funds (FVCs), it reveals that GVC-supported firms surpass those backed solely by domestic PVCs in R&D investment, return on assets (ROA), Tobin's Q, and corporate social responsibility metrics. Acting as government stewards, GVCs effectively fulfill policy goals. Moreover, GVC-backed ventures attract more venture capital following their lead and achieve higher one-day returns at IPOs compared to firms backed solely by private VC funds.

The long-standing debate on the role of economic factors and amenities on talent migration and redistribution foreshadows the importance of spatial economic theoretical thinking in resolving the effects of duality, a point yet to be conclusively addressed in the existing literature. Situated within the framework of new economic geography (NEG), this article introduces an innovative theoretical model – the Dual-Driver (DD) framework– aiming at comprehending the nuanced dual impact of economic and amenity factors on talent movements between regions. While the DD framework retains the mechanisms of increasing returns to scale, iceberg transportation cost, and talent agglomeration presented in the NEG models, it depicts, for the first time, the self-reinforcing mechanisms between non-traded goods (i.e., amenities) and talent agglomeration. The model describes a logic of talent movements influenced by the dual drivers of regional economic factors (nominal wage, the diversity of local manufacturing products) and amenities (the diversity and quality of amenities, transfer payment for talent), among which the economic effects play a predominant role versus the amenity effects. Empirical evidence has been given by the geographical analysis of China's internal talent migration between 2000 and 2015 and the corresponding econometric analysis using the Poisson pseudo-maximum likelihood (PPML) estimation. Our findings furnish a theoretical perspective for comprehending talent geography and offer policy insights into China's logic of talent migration.

The outbreak of COVID-19 forced people to change their lifestyles. In this study, a questionnaire was administered to 1000 Chinese residents to investigate the effects of risk preferences based on prospect theory from behavioral economics, trust in a trust game, other people's expectations, and personal attributes on the adherence to quarantine measures during a pandemic.
Factor analysis divided the preventive behaviors into (1) compliance for self-health care, (2) compliance for going outside, and (3) compliance for staying home alone. In Category 1, those who were more sensitive to gains than losses were more likely to have a health code, wash their hands longer, report instances of COVID-19, and disinfect often. In Category 2, they avoided volunteering at large hospitals, avoided trips to see acquaintances, avoided public walks, avoided meeting strangers, avoided going to garden centers, and wore masks when out and about. On the other hand, those more sensitive to 'losses' than 'gains' were found to work from home and socialize with non-family members in Category 3.
Based on prospect theory, it was found that whether one values gains or losses has a strong influence on preventative behavior. In particular, the fact that those who place greater value on gains than on losses tend to be more proactive in preventative behavior is expected to shed new light on future government guidance for citizens and subtle nudges or prompts to influence behavior.

Environmental degradation, especially air pollution, has been a prevalent problem in China in recent decades. Rather than focus on traditional regulatory policies aimed at enterprises engaged in production activities, this paper studies the effects of the clean heating policy targeting residents in China. Taking the coal-to-gas program as a quasi-natural experiment and using a city-level dataset of daily air quality, we study the effects of the clean heating policy implemented in Beijing and its surrounding areas on air quality with the difference-in-differences method. The results show that the clean heating policy significantly reduced air pollution in coal-to-gas cities, bringing improved economic welfare, with stronger effects in Beijing's neighboring cities. We find no evidence suggesting a decreasing policy effect over time. In addition, we find that increasing subsidies can further enhance the policy's effectiveness. We also test the spatial spillover effects of this policy and calculate its geographical boundary. Changing the energy structure in conjunction with regulating residential emissions is crucial to improving air quality.

“Poverty is the mother of crime”, but existing literature has not yet analyzed the effect of local poverty on crimes in other jurisdictions. Based on 1992–2012 provincial data from China, this paper examines the transborder effects of poverty on crimes, by estimating spatial econometric models. Poverty is found to not only increase local crime, but also raise crime rates in other provinces. This spillover effect is more pronounced between provinces with close geographical proximity, high labor mobility and high dialect similarity. In addition, we compare the effects of increased police spending versus Dibao on poverty-related local and transborder crimes, finding that both can reduce poverty-related local crimes, but only Dibao can reduce poverty-related transborder crimes. The main policy implications of this paper are twofold. First, poverty alleviation can address both the symptoms and the root causes of local and external crimes, with broader and lasting effects than raising police spending. Thus, cross-border resource transfers shall target poverty alleviation; Second, poverty alleviation is not only a concern of the poor areas, but also a challenge for relatively developed areas in terms of crime governance.

Understanding how carbon dioxide (CO2) fertilizes crop yields is crucial for assessing potential threats to food security in a changing climate, characterized by evolving atmospheric CO2 concentrations. Utilizing an instrumental variable based on the long-distance transmission of CO2 from upwind counties, we investigate the causal effects of CO2 on crop yields. Our findings provide evidence that a one-standard-deviation increase in CO2 leads to significant increases in rice, wheat, and corn yields, with effect sizes of 0.3066, 0.7313, and 0.1398 standard deviations, respectively. Moreover, our research provides evidence indicating that the carbon fertilization effects shape the agricultural landscape in China by influencing the acreage shifts across crops. Projecting future crop productions based on a scenario of carbon neutrality aligned with the Paris Agreement, we anticipate that total crop production in China will reach its peak in 2041, followed by a gradual decline. Temperatures will largely offset the predicted changes in crop output brought on by CO2, and the predicted CO2-induced crop production will change accordingly when taking acreage shifts into account.
