垂直专业化贸易:理论模型与基于中国数据的实证

国际贸易理论研究的最新论题之一是对国际垂直分工以及基于垂直分工贸易的关注,本文在较为系统梳理这方面最新研究成果的基础上,从产品内国际垂直分工的角度切入,测算了中国典型年份的垂直专业化贸易程度,并对一些影响因素进行了回归分析。结果显示机械设备制造业占我国垂直专业化贸易份额的30%以上,纺织业其次;关税与垂直专业化贸易扩展呈明显的正相关联系;产业规模较小、中小企业居多的部门一般具有较高的垂直专业化程度。     

资本形成、工业化与经济增长:中国的转轨特征

把中国的经济转轨、增长与工业化联系起来是本文的一个尝试。作者认为 ,中国的经济增长在近年来越来越表现出静态的特征 ,至今尚不具备持续的动态改进的力量 ,而中国在 2 0世纪 80年代以后的转轨过程则又典型地表现为以新兴工业部门的进入和扩张为特征的持续的工业化过程。本文给出了一个帮助理解转轨后中国经济增长可持续性的概念框架和经验描述。在这个框架里 ,中国的经济增长在过去 1 0年来所表现出的下降趋势可以由过度的工业化进程来解释。

Industrial Concentration,Output, and Trade: An Empirical Exploration

This paper explores the relationship between concentration, output and trade usingtheory and empirical analysis of matched data on 82 manufacturing industries in seven countries. It finds that the higher is domestic concentration in an industry compared to international concentration, the lower is the domestic share of world output and thesmaller are net exports. This relationship persists even when industries with high levelsof concentration are excluded.     

中国商业银行曼奎斯特生产率指数分析

本文用非参数的DEA产出前沿面构造出曼奎斯特(Malmquist)生产率指数模型,DEA产出Malmquist可分解为效率变化指数和技术变化指数。并应用该模型时中国14家商业银行1998-2002年的生产率进行了分析,得出中国商业银行生产率在考察期内是提高的,但技术进步对生产率提高的作用要大于代表管理水平的效率变化指数对生产率提高的作用。同时也得出,生产率的提高与所有制结构有直接关系。     

Risk Awareness of Interpersonal Trust and Entrepreneurship in China: Evidence from Survey Data

This paper aims to build a theoretical framework for the influence of risk awareness of interpersonal trust (RAIT) on entrepreneurship, and explores the influence of RAIT on entrepreneurship with the micro survey data from the Chinese General Social Survey (CGSS) 2010–2013. The study found that, individuals with higher level of RAIT, their probability of starting new business will increase significantly, and with every increase of RAIT level, the probability of business venturing increase almost 4.0%. No mediation effects of information screening and cooperative mechanism are found in the relationship between RAIT and entrepreneurship. Moreover, during the venturing process, risks accompanying interpersonal trust cannot be reduced by social input; the reduction occurs only in eastern China where the economic system and the industrial development standards are more comprehensive and mature. This paper contributes to the literatures in the following two areas: it provides new evidence on how to deal with risks in the entrepreneurship process that accompanying interpersonal trust; meanwhile, it provides an explanatory mechanism on how the risk awareness affects business venturing.     

Energy and CO2 emission relationships in the NAFTA trading bloc: a multi-regional multi-factor energy input–output approach

The North-America Free Trade Agreement (NAFTA) has brought together the economies of Canada, Mexico, and the US into forming one of the largest trading blocs worldwide (within the top CO₂ emitters). However, the current global protectionist discourse threatens the agreement. This paper analyzes the energy and energy-related CO₂ emission relationships between NAFTA countries in 2014 to gain insights into the climate change implications of current integration and the possible cancelation of the agreement. The analysis is performed with a multi-regional version of the multi-factor energy input–output model. The results show that NAFTA has not built a single integrated energy system, though it has helped reduce energy-related CO₂ emissions. Moreover, if NAFTA is not revoked, further integration would depend on the capacity of the Mexican energy sector to converge to the performance of its trade partners’ energy sectors. Conversely, a broken deal would induce negative environmental externalities.     

长江经济带生态保护效率与科技服务业发展效率时空关联分析

建立超效率DEA模型并运用视窗分析测算2010-2017年长江经济带11个省市生态保护效率与科技服务业发展效率，通过空间计量模型分析后者对前者的影响。结果表明：科研技术服务业效率对当地及周边地区的生态保护效率具有正向影响；科技资本服务业效率对当地生态保护效率具有正向影响，但对其周边地区有抑制效应；科技宣传服务业未对生态保护效率产生显著影响。据此，提出长江经济带通过提高科技服务业效率改进生态保护效率的对策。     

环境约束下中国工业企业创新效率评价及影响因素研究

本文应用SBM模型的改进DEA模型以及DEA-Tobit法对中国2006～2015年环境约束下工业企业技术创新效率及其影响因素进行实证分析，研究结果表明，非期望产出对企业效率评价结果有较大影响，北部沿海综合经济区的环境效率值最高；西北综合经济区、长江中游综合经济区、黄河中游综合经济区、东北综合经济区环境效率值相对较差。政府支持力度、企业规模与环境约束下的工业企业技术创新效率呈正相关关系，企业聚集度与其呈负相关关系，而企业技术水平与从业人员素质对其影响较小。
