With the development of Jiangsu, the improvement of the use of public goods supply performance is very important for Jiangsu's economic development. This paper first uses data envelopment analysis to analyze and evaluate the public goods supply performance in Jiangsu region in 2015, and then uses Malmquist index method to analyze the serial data of 13 cities in Jiangsu Province from 2010 to 2015. The study found that Jiangsu's public goods supply performance is generally good, but there are still large differences between cities, reflected in scale returns, scale efficiency, and technical efficiency. Based on the results of DEA analysis and Malmquist index analysis of the use of public goods supply performance in cities in Jiangsu Province, this article proposes relevant countermeasures to improve performance.
