Study on the Countermeasures and Insights of Consumption Structure Optimization under the Strategy of Expanding Domestic Demand— Multi-period and Multi-dimensional Analysis Based on Kunming Panel Data from 2017 to 2024

In 2025, the Chinese Government Work Report proposed accelerating the stimulation of domestic demand, particularly in the area of consumption. This study takes Kunming as a case example, integrating 44 types of consumption and economic indicators, and employs the Pearson correlation coefficient and principal component analysis to construct a multidimensional analytical framework. The findings indicate that demand for non-essential and high-end consumer goods in Kunming remains persistently sluggish; consumption related to the real estate industry chain has declined significantly; there is an excessive reliance on government spending and public services; the transformation of traditional retail formats is lagging; income distribution and savings tendencies are constraining demand; and fluctuations in imports and exports are exacerbating consumption uncertainty. It is recommended that Kunming optimize its consumption supply structure, stabilize the real estate industry chain, enhance endogenous market momentum, accelerate digital transformation, improve the income distribution mechanism, and strengthen the competitiveness of local brands. This research offers valuable insights for China and other countries seeking to promote consumption.
