In this paper, the method of principal component analysis is used to evaluate overall comprehensive level of urban living garbage treatment performance of provinces in china. Then we analyse a variety of factors that affect China city life garbage disposal performance by using empirical research and VAR model. We find that the main factors which directly affect the performance of urban garbage disposal in China are labor and operation mode. At the same time, the operation mode is an exogenous factor, which cannot be realized without the external driving force. While labor is indirectly driven by money and government regulatory factors, namely funds and government regulatory factors through the path of labor factors affect performance. According to the research conclusion, we get some suggestions, which will enhance the level of China city life garbage processing performance and the government regulation of public enterprise.
