Empirical Analysis of Urban Economic Development Level in Heilongjiang Province Based on Stata

The purpose of this paper is to study the actual economic development of cities in Heilongjiang Province since the occurrence of COVID-19. The Stata software is adopted to carry out descriptive statistics, correlation analysis, regression analysis, and factor analysis on the data of the existing statistical yearbook of Heilongjiang Province in 2021, and then various empirical analysis results are obtained. Through correlation analysis, it can be seen that the regional GDP of each city in Heilongjiang Province has the highest correlation with public financial revenue and total loans. Through regression analysis, it can be seen that the regional GDP has the highest correlation with the gross output value of agriculture, forestry, animal husbandry, fishery, and public finance revenue. It can be seen from the principal component factor analysis that the comprehensive strength of Harbin is the strongest among all cities in the province. Finally, according to the results of various empirical analyses, I give my suggestions. First, give play to the radiation and driving role of Harbin’s modern metropolitan area. Second, build the backbone of the rise of the eastern city cluster industry. Finally, consolidate the achievements of urban green economy development in ecological areas.
