The influence of international oil price fluctuation on the exchange rate of countries along the “Belt and Road”

In recent years, the international crude oil price has become increasingly volatile. It influences the exchange rate changes of relevant countries through economic growth, price level, international balance of payments, and other channels. Such exchange rate fluctuations have caused certain risks for the development of China’s “Belt and Road” Initiative. This article analyzes the impact of oil price changes on the exchange rates of countries. Because the fluctuation of oil prices and exchange rates has shown the characteristics of multiple time scales, this study used the empirical mode decomposition (EMD) method to obtain the long-cycle and short-cycle sequences of oil prices and the exchange rates of various countries, then analyzed the impact of oil price changes on exchange rates under different time scales. The results showed that oil price fluctuations have an impact on the exchange rate changes of countries along the “Belt and Road” under different time scales. However, this effect is asymmetric between oil-producing countries and non-oil-producing countries, and the transmission path of oil prices to exchange rates varies from cycle to cycle.     

Smartphone-based agricultural extension services and farm incomes: Evidence from Zhejiang Province in China

Smartphone use in rural China has grown rapidly, leading to the fast development of smartphone-based agricultural extension services. However, there is limited research on the income effects of smartphone-based agricultural extension services in rural areas. In this study, we analyze the causal effects of smartphone-based agricultural extension services (“Zhe'yang'shi” WeChat application as an example) on farm incomes in Zhejiang, China, using a staggered difference-in-differences method with panel data from 400 crop farmers. Our results show that adopting smartphone-based agricultural extension services increases farm income from soil testing formula fertilizer fields by 15.39% and total farm income by 16.31%.     

Complimentary competition: The impact of positive competitor reviews on review credibility and consumer purchase intentions

Online reviews are important decision aids for consumers, but not all reviews are perceived as equally credible, which may hinder consumer decisions. This research identifies positive competitor reviews as a novel source of credible reviews. A pre-test and four studies show that consumers perceive positive reviews written by competitors as more credible than similar consumer-generated reviews. This is because, compared to lay consumers, competitors are perceived as less likely to be compensated for their positive reviews. Positive competitor views, in turn, elicit greater intentions to purchase the reviewed product. Positive competitor reviews are expected to contribute to a “coopetitive” environment.

Digital Economy,Entrepreneurship, and High-Quality Economic Development: Empirical Evidence from Urban China

The paper discusses the effects of the digital economy on high-quality urban development and its mechanism. Theoretically, the digital economy can empower high-quality development by boosting entrepreneurial vitality. Empirically, the paper measures the overall level of the digital economy and high-quality development of the 222 Chinese cities at and above the prefecture level during 2011–2016, depicts the entrepreneurial vitality of the cities with the microscopic data of the business registration information and makes quantitative analysis on this basis. The result shows: Digital economy has remarkably improved high-quality development and this conclusion still exists after the robustness test selecting historical data as the instrumental variables and the Broadband China pilot policy as the quasi experiment. The analysis of the mechanism of action indicates that encouraging public entrepreneurship is an important mechanism of the digital economy to release the dividend of high quality development. Finally, thanks to the threshold model and the spatial model, it is found that the positive effect of the digital economy has the characteristics of nonlinear increment and spatial spillover of the “marginal effects.” The research of the paper stimulates the reasons for high-quality development and the understanding of the effects, mechanisms and regional differences of high-quality development empowered by the digital economy.     

Analysis of the impact mechanism of environmental regulations on corporate environmental proactivity—based on the perspective of political connections

Previous studies have demonstrated the favorable effects of political connections on corporate environmental proactivity (CEP). However, few studies have further verified whether this is definitively the case under environmental regulations and their underlying reasons, which would help elucidate the performance and motivation of politically connected firms’ (PCFs’) environmental proactivity. Using data from Chinese A-shares-listed industrial firms from 2010 to 2016, we find that environmental regulations can significantly improve CEP. Compared with non-politically connected firms (NPCFs), PCFs are more responsive to environmental regulations. Counterfactual analysis based on corporate resource conditions suggests that firms that are more supported by government in debt financing and show higher environmental proactivity are only found in PCF samples. In order to maintain this political relationship and continuously obtain debt financing support, PCFs tend to “bind” their business decisions to the government’s environmental governance objectives and display higher environmental proactivity. In summary, PCFs’ environmental proactivity involves self-interest decisions based on their resource conditions.     

建设用地“增存挂钩”机制的模型解析与优化--基于边际分析方法

文章基于经济学边际分析与数学模型分析方法,解析现行建设用地“增存挂钩”机制的内在机理。研究发现:“增存挂钩”机制通过存量土地处置规模直接决定新增计划指标数量的方式,实现地区存量土地处置成本与新增计划指标收益相关联,从而具备由最有效的存量土地处置规模核算得到最优新增计划指标量的可能性。但是,在节约集约用地水平高的地区,现行挂钩规则可能无法核算得到最优增量,不能充分发挥该机制的激励作用。针对可能出现的政策失灵问题,建议通过优化新增计划指标核算规则和探索建立“增存挂钩”机制下新增计划指标跨区域交易机制两种途径,提升“增存挂钩”机制在节约集约用地水平较高地区的实施效率。     

Study on Medium- and Long-Term Fiscal Policies to Cope with Climate Change under the “Dual Carbon” Goals

Carbon peaking and carbon neutrality constitute an extensive, profound and systemic economic and social change. It is worthwhile to explore how fiscal policy, as a key institutional arrangement in the public policy system to cope with climate change, can play a fundamental and pillar role. Based on literatures, theories and empirical materials, this paper systematically explores the relationship between climate change and public finance. The fiscal impact of climate change will eventually be reflected in fiscal behavior, fiscal costs and fiscal relations, and the fiscal system has the adaptability of an “automatic stabilizer” and the proactiveness to enable the Discretionary Approaches function when facing climate change impacts. This implies such a governance logic of fiscal policy that is systematic, forward-looking and flexible in addressing climate change. In the future, it is necessary to further incorporate climate change or related environmental factors into the fiscal policy framework, target the two key aspects of mitigation and adaptation, and carry out a holistic, systematic and forward-looking reform of the existing fiscal expenditure policy, fiscal revenue policy, fiscal investment and financing policy, government budget system, government procurement policy and ecological compensation policy. While highlighting the “governance” function of fiscal policy in addressing climate change, Chinese government needs to strengthen the coordination and collaboration between fiscal policy tools and other public policies, and magnify the governance effectiveness of fiscal policy in the process of addressing climate change. This paper helps understand the positioning, role and influence of fiscal policy in the process of addressing climate change, provides a basis for better playing the fundamental and underpinning role of the modern fiscal system in the governance of ecological civilization, and presents an analytical framework for building a theoretical system of ecological fiscal governance.
