Small and medium-sized technology-based enterprises are important carriers of scientific and technological progress and independent innovation in cities, regions and even countries, and play a crucial role in the process of resource based cities getting rid of resource dependence and realizing industrial structure transformation. Based on the questionnaire data and city cross-section data of small and medium-sized technology-based enterprises in Shanxi Province, this paper studies the impact of financing characteristics of resource-based province on the growth of small and medium-sized technology-based enterprises from the perspective of financing structure and financing efficiency.The research finds that: Firstly, by the end of 2021, the small and medium-sized technology-based enterprises in Shanxi Province are in a rapid growth period, and their sustainable development capacity needs to be further improved.Secondly, influenced by the development history of resource-based provinces and industries, the development of capital market lags behind the demand for transformation. The financing of technology-based enterprises mainly depends on internal financing and bank loans.Thirdly, in terms of financing structure, both the level of debt and the structure of debt sources have significantly promoted the growth of enterprises, while the term structure of financing has significantly inhibited the growth of enterprises. Fourthly, in terms of financing efficiency, financing efficiency significantly promotes the growth of enterprises. Finally, some suggestions are put forward.
