【摘要】 基于世界银行的指标体系，采用改进BOD模型重新计算2013—2019年“一带一路”沿线国家营商环境便利度得分及排名，并与世界银行的评价结果进行对比，进一步基于改进的BOD-Malmquist模型测度沿线国家营商环境的动态变化及原因。研究发现，改进BOD模型可以很好地兼顾各个国家指标间的区别，“一带一路”沿线国家营商环境存在明显差异，得分较低国家主要集中在南亚和西亚地区。十个营商子环境中，开办企业和跨境贸易得分普遍较高，而办理破产和执行合同得分偏低。2013—2019年间绝大多数沿线国家营商环境得以改善，相较于区域政策的影响，各经济体通过自身努力对营商环境改善的积极影响更为明显。更多还原

【Abstract】 This paper recalculates the ease of doing business scores and rankings of countries along the Belt and Road from 2013 to 2019 using the improved BOD model based on the World Bank’s index system, then compares them with the World Bank’s evaluation results. The paper further measures the dynamic changes of the business environment of countries along the Belt and Road based on the improved BOD-Malmquist model and analyzes the reasons for the changes. The study finds that the improved BOD model can take into account the differences among the indicators of each country, the business environment of the countries along the route varies significantly, and the countries with lower scores are mainly concentrated in South Asia and West Asia. In addition, among the ten business sub-environments, business start-up and cross-border trade generally score higher, while bankruptcy and contract enforcement score lower. Most of the countries along the route have improved their business environment during2013-2019, and the positive impact of each economy’s own efforts to improve the business environment is more obvious than the impact of regional policies.更多还原
