中国经济高质量发展的测度研究
A Study on the Measurement of China’s High-Quality Economic Development

中国经济已经进入高质量发展阶段，测度其发展水平有助于提升区域经济发展质量。本文基于构建的综合指标体系，采用CRITIC法评价中国省际经济高质量发展水平，并结合Dagum系数分解、核密度估计等方法分析其差异来源、空间动态演进趋势，得出以下主要研究结论：1) 中国经济高质量发展水平有所提升，呈现多级分化态势；2) 中国经济高质量发展水平总体差距呈波动下降，区域间差异远超区域内差异；3) 中国经济高质量发展表现出一定的空间溢出效应，多数省份间呈现出低–低聚集形态。为此本文提出相应建议，为提升经济高质量发展水平、缩小区域经济发展差距提供决策参考。
China’s economy has entered a stage of high-quality development, and measuring its development level helps to improve the quality of regional economic development. Based on the comprehensive index system, this paper adopts the CRITIC method to evaluate the level of high-quality develop-ment of China’s provincial economy, and combines the Dagum Gini coefficient decomposition, kernel density estimation and other methods to analyze the source of differences and spatial dynamic evolution trend. The main conclusions are as follows: 1) The level of high-quality development of China’s economy has been improved, showing a multi-level differentiation trend; 2) The overall gap of China’s high-quality development level has fluctuated and declined, and the difference between regions is far greater than the difference within regions; 3) China’s high-quality development has shown a certain spatial spillover effect, and most provinces show a low-low aggregation pattern. Therefore, this paper puts forward corresponding suggestions to provide decision-making reference for improving the level of high-quality development of economy and narrowing the gap of regional economic development.
