The development and take-off of China's economy cannot be achieved without Small and medium-sized enterprises (SMEs). At present, with the increasingly fierce competition on the global economic stage and the constraints of resources, environment and other multiple factors, adjusting the economic structure and promoting industrial transformation and upgrading have become the general trend of economic development. The way to take the pulse of growth, supporting and promoting the sustainable and healthy development of various types of SMEs have become one of the key concerns of local governments. This paper carries on elementary research on the relationship between the industrial upgrading of SMEs and the public policies of government by taking Huishan District, Wuxi City, China, as an example. This paper describes the basic theories related to the industrial upgrading of SMEs and discusses the necessity of government support for the industrial upgrading of SMEs through public policies. Based on the empirical analysis of the current situation and problems of SMEs in Huishan District, Wuxi City, the principles to be followed in supporting the industrial upgrading of SMEs in Huishan District, Wuxi City from the perspective of government public policy are proposed by comparing and learning from the experience of foreign developed countries, and the basic framework of the public policy support system for SMEs in Huishan District, Wuxi City is constructed.
