自然开放度、政策导向开放度与劳动生产率提升——理论和基于中国省际面板数据的实证研究

本文以李嘉图模型为基础,分析了贸易开放对提升中国劳动生产率的效应。本文使用1994-2005年间中国省际面板数据,就贸易开放对提升中国劳动生产率水平所产生的效应进行了实证研究。本文得出两个重要的分析结果:第一,贸易开放可以通过比较优势来确定一国专业化产品的生产,如果一国的比较优势存在于干中学系数较大的部门,贸易开放将提高劳动生产率;但若一国的比较优势存在于干中学系数较小的部门,贸易开放将降低劳动生产率;第二,本文将贸易开放度分解为自然开放度和政策导向开放度,结果发现,当自然开放度较小时,政策导向开放度的增加将降低劳动生产率;当自然开放度较大时,政策开放度的增加将提高劳动生产率水平。     

贸易开放与发展中国家收入差距扩大——基于中国的理论与实证分析

文章将人力资本结构因素纳入到贸易开放与发展中国家内部收入差距关系的分析框架之中,通过理论推理和实证检验考察了贸易开放、人力资本结构对发展中国家收入差距扩大的影响机制、条件与力度.研究表明,贸易开放对发展中国家收入差距扩大的影响不但与其所带来的技术进步类型有关,还与该国的产业发展战略和人力资本(人才供给)结构密切相关.就我国而言,人力资本结构升级速度慢于贸易产品结构升级速度,是贸易尤其是出口导致收入差距扩大的重要条件.     

服务贸易开放的经济效应及相关指标的构建

服务贸易是当今国际贸易中发展最为迅速的领域。随着国际服务贸易的发展及其在国际贸易中的比重日益上升世界各国纷纷加强了对服务贸易的研究。本文从服务贸易开放理论的回顾与比较优势理论适用的评价入手分析服务贸易开放的福利效应,说明开放的好处和必要性,并构建了服务贸易开放的衡量指标体系。     

经济开放进程中金融危机冲击比较研究

亚洲金融危机和美国次贷危机对中国经济产生了明显的影响,但在经济开放进程中这两次危机冲击特点和结果均有所不同。本文对开放进程中金融危机向国内传导的渠道进行分析,利用指标对比分析法、干扰模型、脉冲响应以及方差分解技术分析比较了两次金融危机对我国冲击的不同影响机制。研究结论表明,在经济开放进程中,美国次贷危机对国内经济的冲击要远超于亚洲金融危机;在资本项目没有完全开放条件下,国际贸易渠道越来越成为国际金融危机冲击向国内传导的重要渠道;尽管经济开放增加了金融风险,但良好的制度设计和金融风险管理手段的加强,使金融危机通过金融渠道传导而产生的冲击波有所降低。     

How do trade openness,public expenditure and institutional performance affect unemployment in OIC countries? Evidence from the DCCE approach

This study explores the relationship between trade openness, public expenditure, institutional performance, and unemployment in member countries of the Organization of Islamic Cooperation (OIC) (formerly the Organization of the Islamic Conference). The conventional panel data techniques overlook cross-sectional dependence and yield-biased results. A new methodology called dynamic common correlated effects (DCCE) is employed to deal with the issue of cross-sectional dependence. The long-run results demonstrate that trade openness is inversely and significantly associated with overall unemployment and youth unemployment in lower-income as well as all the OIC economies and positively correlated in the higher-income OIC group. Public expenditure has an inverse and significant correlation with unemployment in OIC countries overall and higher-income OIC countries. Moreover, institutional performance and foreign direct investment are negatively related to unemployment in all OIC economies. The research shows the need for the continuation of open trade policies, strong institutions, and higher public expenditure in the OIC countries in order to decrease overall unemployment—in particular, youth unemployment.     

Trade in health products and population health: A long-run relation

The effect of trade on different economic outcomes has been extensively studied but the literature on the specific effects of trade on health outcomes has remained relatively scanty. Our paper fills in the gap by examining the long-run association between import expenditures on health products and longevity in a cross-country panel setting of 32 developed and 24 developing countries, covering 1990–2018. It accounts for both time-series properties and cross-country heterogeneity, while remaining robust to omitted variables and endogeneity problems, by applying panel cointegration techniques. The results reveal that per capita medical import expenditure on pharmaceuticals, aggregate medical products and medicines have contributed around 0.34, 0.35 and 0.30 percentage points, respectively to the annual increase in life expectancy for an average country in our sample. The findings suggest that higher per capita import expenditure on health products can increase longevity significantly in the long-run. The results remain robust to cross-sectional dependence, sub-samples of developed and developing countries and alternate measures of health outcomes such as adult mortality rates. These findings set the context for treating health product imports as critical for long-term improvements in population health and outlines the need for greater coordination between health and trade policymakers for improving population health.     

Is environmental labeling certification a “green passport” for firm exports in emerging economies? Evidence from China

As the demand for more environmentally friendly products continues to increase, environmental label certification (ELC), as a voluntary environmental practice (VEP), has become a commonly used strategy by firms responding the green demands of the international market. While ELC is playing an increasingly important role in global trade, how ELC affects firms’ exports, especially how it affects the exports of those firms in emerging economies, remains unknown. This study explores the impact of ELC on firms’ exports. Insights are provided from resource-based views (RBV) by analysing China's A-share listed manufacturing firms to estimate the impact of China's ELC on exports. Our empirical results show that ELC can promote firms’ exports, because ELC emphasizes firms to reduce pollutant from the source, thereby, brings about cost advantage and green product differentiated advantage to boost high-quality exports. Using a series of robustness tests, we provide corroborating evidence for our hypotheses. The export-enhancing effect of ELC is impacted by the institutional context of emerging economies, as specialized market intermediaries and greater openness to the global market strengthen the export-enhancing effect of ELC. This research not only contributes to the literature, but also provides a reference for policy-makers and managers in using ELC to develop green trade.     

Financial openness and profitability premium: Causal evidence from the Shanghai-Hong Kong Stock Connect

This study explores the impact of capital market openness on the profitability premium by using the Shanghai-Hong Kong Stock Connect (SHKSC) programme as an exogenous shock. The empirical results show that (1) we can basically rule out the mispricing mechanism driving the significant profitability premium in China; (2) following SHKSC, the expected stock returns increase more across less profitable firms, and the less profitable firms have more increases in illiquidity, capital structure and information disclosure quality; and (3) the results are still robust after using propensity score matching analysis, deleting the highly volatile periods and conducting a firm-level test with the triple-differencing design.     

数字贸易如何影响贸易高质量发展——基于贸易全要素生产率视角的经验证据

贸易高质量发展是高效优质利用国内国际两种市场和资源的关键抓手，能够有力推动双循环新发展格局及经济高质量发展。基于2010—2020年中国省际数据，实证考察了数字贸易对贸易高质量发展的影响及相关作用机制。研究发现，一是数字贸易能够有效促进贸易高质量发展，且这种影响受到市场开放度的调节；此外，从数字贸易各维度看，其对贸易高质量发展的影响存在异质性。二是数字贸易能够通过产业结构和物流业升级对贸易高质量发展产生推动作用。三是空间回归表明某一地区数字贸易发展会对周边地区产生负向溢出效应。进一步的拓展性分析发现，在东部、中部地区数字贸易能够有效推动贸易高质量发展，对西部地区虽有促进作用，但并不明显；数字贸易各维度中，数字技术在中部地区对贸易高质量发展具有显著促进作用，数字产业化贸易在东部、中部地区对贸易高质量发展具有显著促进作用。研究有助于理清数字贸易和贸易高质量发展之间的逻辑关系及作用机制，为我国通过发展数字贸易进而推动贸易高质量发展提供了理论和经验支撑，为政策决策提供建议。     

Trade openness and financial development in sub-Saharan Africa: The role of institutional structures

This article examines the role of institutional structures in the relationship between trade openness and financial development in sub-Saharan economies. The study is based on empirical data from sampled sub-Saharan African countries for a period of 1996–2017. The system generalized method of moment was employed to estimate the models. The findings suggest that, even though trade openness has a positive significant influence on the level of financial development in sub-Saharan African economies, this relationship is enhanced through the presence of good institutions in these economies. Thus, for these economies to realize the full benefit of the effect of trade openness on financial development, they need to strengthen their institutions.
