摘要
本文运用DEA-Tobit模型对全球84个国家投资效率的测算发现,中国投资效率在G20国家处于中等水平,近年来有快速下降趋势,变化趋势与韩国在相近发展阶段较为相似.实证研究发现,当一国进入中高收入国家之列,投资效率随GDP增加而递减趋势明显,更大的人口规模、更完善的基础设施水平、更有效的政府治理、更稳定的金融环境和更高的人力资本质量有利于提高投资效率.建议继续促进劳动力合理流动,根据人口流动规律优化投资布局,提高基础设施的系统集成功能,提高现代化治理水平和金融管理水平,提高人力资本质量,稳定并提高中国投资效率.
Abstract
This article uses the DEA-Tobit model to measure the investment efficiency of 84 countries around the world,and finds that China's investment efficiency is at a medium level among the G20 countries,with a rapid declining trend in recent years,and the trend is similar to that of South Korea at a similar stage of development.Em-pirical research has found that when a country enters the ranks of middle-and high-income coun-tries,the investment efficiency decreases signifi-cantly with the increase of GDP,and a larger pop-ulation size,a better level of infrastructure,more effective government governance,a more stable financial environment,and higher quality of human capital are conducive to improving investment effi-ciency.It is recommended that China continue to promote the rational mobility of labour,optimize the layout of investment in accordance with the law of population mobility,improve the system integra-tion function of infrastructure,improve the level of modern governance and financial management,and improve the quality of human capital,to stabilize and improve China's investment efficiency.
