“一带一路”建设对于经济新常态下中国扩大和深化对外开放,促进沿线国家经济持续快速发展以及实现合作共赢具有重要意义。本文选取反映投资便利化水平的4个一级指标和22个二级指标,构建投资便利化指标体系,运用主成分分析法测评了中国与周边国家的投资便利化水平。研究结果表明:中国的投资便利化水平相对周边国家最高,接下来是印度,吉尔吉斯斯坦的投资便利化水平最低;投资便利化指标体系中各二级指标的便利化水平指数相差不大且普遍较低,整体投资环境有较大的提升空间。中国与周边国家应通过强化基础设施建设、加强政策沟通、提高金融服务效率、营造良好的商业投资环境等举措,共同提升投资便利化水平。

"The Belt and Road Initiative" is of great significance of expanding and deepening China's opening to the outside world, promoting the sustained and rapid economic development of the countries along the Belt and Road and achieving win-win cooperation in the new norm of China's economy. This paper selects 4 first-level indicators and 22 second-level indicators that reflect the level of investment facilitation, systematically constructs the measuring system of investment facilitation, and uses the principal component analysis method to measure the level of investment facilitation in China and surrounding countries. The results show that the level of investment facilitation in China, is highest compared with neighboring countries, followed by India, and Kyrgyzstan is the lowest. In the investment facilitation index system, the level index of the specific second-level indicators varies little and is generally low, so there is much room for improvement in the overall investment environment. China and its neighboring countries should work together to promote investment facilitation through such measures as strengthening infrastructure construction, enhancing policy communication, improving the efficiency of financial services and creating a favorable business investment environment.
