Research on regional difference of economic development level in Zhejiang Province based on factor analysis

Regional economic disparities are widespread, especially in China. This is reflected not only in the differences between the four regions, but also in the differences between provinces. At the same time, the regional economic differences within each province are also very obvious. This paper studies the gap between the economic development levels in Zhejiang Province, which contributes to the balanced development and sustainable development of the overall economy of Zhejiang Province, in order to intuitively see the gap between the cities. This paper uses SPSS to reduce the dimension of factor analysis and calculate the comprehensive score through 10 indicators reflecting the level of economic development in 11 cities. Finally, this paper finds that the economic development of each city in Zhejiang Province has great potential. But at the same time, it exposes the imbalance of economic development in the province. The economic development level of Hangzhou, Ningbo and Zhoushan is far higher than that of other cities in the province, and the economic development level of some cities is general. The development level of some cities is poor. According to the research results, the causes and problems of the current situation of economic development are analyzed. Reasonable suggestions are put forward to further promote the coordinated development of the economy.
