Measurement and Analysis of Economic High-quality Development

China’s economic development has shifted from high-speed growth to high-quality growth. The measurement and analysis of the high-quality economic development of prefecture-level cities in the province is conducive to the coordinated economic development of cities in the province and the improvement of the overall quality of economic development. This paper takes 11 prefecture-level cities of Shanxi Province, a resource-based province from 2010 to 2018, as the research object, and constructs an evaluation system of economic high-quality development indicators from the aspects of economic growth, economic structure, and economic benefits. At the same time, the high-quality economic development level and influencing factors of prefecture-level cities are selected for specific measurement and in-depth analysis. The research results show that: First of all, during the sample period, the high-quality economic development level of Shanxi Province showed a slow upward trend. Secondly, the high-quality economic development of provincial and municipal-level cities is uneven. Finally, the core driving force is economic benefits for high-quality economic development. All of the above are significant factors that cause differences in the quality of economic development of provincial and municipal cities. According to the analysis result, the paper last gives some policy suggestions.
