区域一体化有利于减排吗？

将环境污染视作非期望产出,在一个拓展的增长收敛框架下讨论了区域一体化的环境效应及其理论机制。基于2003-2014年长三角城市群和珠三角城市群的数据,构建了一个测度区域一体化的新方法,运用工具变量法和双重差分法估计了跨省城市一体化和省内城市一体化对污染排放强度收敛的影响。实证结果显示:区域一体化显著促进了城市间污染排放强度的收敛并有利于减排,且近年来这种减排效应愈明显。污染排放强度呈现出条件收敛特征,经济增长收敛是污染排放收敛的重要原因。中国应利用好区域一体化促进地区协调发展和减排的双重政策红利,进一步促进区域一体化和同城化,大力发展城市群经济,构建城市间共生互利的发展格局,实现共同减排。

Economic contribution of essential air service flights on small and remote communities

The Essential Air Service Program (EAS) has attracted considerable criticism and has been a target for either modification or complete termination almost since its inception through the Airline Deregulation Act in 1978. Although its opponents emphasize the program's inefficiency, its supporters claim that the program is crucial to accessing small and remote communities, which helps them develop economically and socially. This paper demonstrates the economic contributions of EAS flights to small and remote communities. Using a two-stage least squares estimation, the major findings indicate that a 1% increase in air passenger traffic in EAS airports with a minimum annual air passenger traffic of 1000 likely leads to a 0.12% increase in per capita income of the community served by that airport. Our results also suggest that EAS communities that are able to sustain their subsidized flights experienced higher per capita income growth in the 1999–2011 period than did ex-EAS communities that lost their flights as a result of non-eligibility.     

Multi-sectoral interdependencies of regional public infrastructure investments

Public investment decision-making processes involve multiple and interrelated sectoral and regional policy objectives and budget constraints. This paper presents a dynamic spatio-economic model that considers multi-sectoral investment interdependencies using data at the prefecture level in Greece. The expenditure allocation dynamics of most types of regional public investment are found to be competitive with each other. This outcome is attributed to the lack of policy coordination, technological and budget constraints, geographical factors, and equity and political considerations. The investment interrelationships may have a significant effect on future state funding needs and the strategic assessment of infrastructure development at the country level.     

A new assessment of economic integration in East Asia: Application of an industry-specific G-PPP model

It is well known that intra-industry trade and cross-border production networks have promoted economic growth and regional integration in East Asia. However, regional supply and production chains may have been formed differently across industries, reflecting different degrees and a different scope of regional economic linkages at an industry level. This paper makes a threefold contribution. First, to assess industry-level differences, this study adopts the generalized purchasing power parity (G-PPP) model using industry-specific producer prices. Second, the momentum threshold autoregressive (M-TAR) model is employed to allow for possible nonlinearity arising from the dynamic nature of regional economic growth and development. Third, the Granger causality test is also conducted to assess whether regional economies have autonomously integrated. The empirical results reveal that economic integration has progressed more autonomously in the electrical industry, as well as in the transportation equipment industry, as China and the ASEAN countries have become the final destination markets for finished products in these two industries.     

Tourism and regional income inequality: Evidence from China

This study examines the role of tourism development in reducing regional income inequality in China. First, the theoretical foundation for how tourism affects regional income inequality is discussed. Second, based on the conditional convergence framework, this study proposes a spatiotemporal autoregressive model to capture spatial and temporal dependence as well as spatial heterogeneity. Tourism development is introduced as a conditional convergence factor in an attempt to examine whether the convergence speed is accelerated by regional tourism development. Third, the effects of international and domestic tourism in narrowing regional inequality are compared both globally and locally. The empirical results indicate that tourism development contributes significantly to the reduction of regional inequality, with domestic tourism making a greater contribution than international tourism.     

区域中心城市创新生态圈要素架构、生态特征与运行机制

区域中心城市创新生态圈以生物学为隐喻，注重发挥创新主体的能动作用，能够放大区域中心城市发展优势。在回顾创新生态圈理论渊源的基础上，界定区域中心城市创新生态圈内涵，明确创新生态圈要素构成；以企业聚集发展为逻辑起点，探讨区域中心城市创新生态圈生态特征；基于生态学、创新理论等跨学科知识，构建区域中心城市创新生态圈演进模型，探究其运行机制。研究认为，区域中心城市创新生态圈具有开放式协同、动态自调节、多样性共生、自组织演化等生态特征，其运行机制由协同共生机制、风险识别与防控机制、利益分配机制和环境匹配机制共同组成。     

高新区设立与区域绿色经济增长——基于PSM-DID模型

运用非径向方向距离函数测算了2003-2016年中国277个地级市绿色全要素增长率，在此基础上，采用倾向匹配的双重差分法实证评估国家高新区对绿色经济增长的影响，并分析其影响机制和传导途径。结果表明：国家高新区显著推动了绿色经济增长，主要通过推动“技术领导者转移效应”实现;国家高新区对绿色经济增长存在明显异质性，呈现出“边际效应递减”。中部地区、低等级城市和“成长期”国家高新区对绿色经济增长促进作用较大，高新区对协调区域绿色发展具有重要意义。传导途径表明，国家高新区以创新驱动人力资本效应、财政配置效应和对外开放效应促进绿色经济增长。     

国家重点科技资源支撑区域创新经济产出的空间差异研究

根据2011-2014年科技部《国家重点科技基础条件资源调查表》以及国家统计年鉴数据,首先,使用赫芬达尔指数定量描述了利用国家重点科技资源进行创新活动的非均衡性。其次,使用网络DEA方法,实证分析了2012-2014年中国(内地)各省份国家重点科技资源对区域创新发展的支撑作用。研究表明,国家重点科技资源对区域创新发展的支撑作用不仅取决于资源创新生产阶段,而且受制于重点科技资源支持下的区域创新发展阶段。重点科技资源的支撑作用还有较大提升空间,70%的省份创新成果转化能力有待提高,且大部分省份的国家重点科技资源未实现优化配置。此外,全国及东部、中部和西部国家重点科技资源对区域创新发展的支撑效率不存在绝对收敛趋势。     

Food safety recall effects across meat products and regions

Food safety is one of the key issues for the international meat market. As a major meat exporter, few things facing the U.S. meat industry in recent years have garnered more attention than food safety events and policies. The impacts of Food Safety Inspection Services (FSIS) recalls on United States consumer meat demand are estimated using monthly grocery-scanner data identifying effects across products, geographic regions, and recall type. Results suggest beef E. coli recalls significantly reduce the demand for recalled ground beef contemporaneously among most, but not all, regions in the United States. Evidence of heterogeneity in demand impacts across regions and products is provided for the first time. Domestic and international implications for policy makers, industry leaders, and researchers are discussed.
