Abstract: Taking 8 cities in Chengdu Plain urban agglomeration as examples, this present paper evaluates the efficiency of public sports service through data envelopment analysis. The results show that public sports service efficiency in Chengdu Plain urban agglomeration is not high, there being problems of input redundancy and insufficient output and all the cities failing to carry out public sports service construction under the optimal scale income model. Using the Tobit regression model, the paper makes a judgement on the correlation between the external social environment factors and the public sports service efficiency. Based on the results, this paper proposes4 development strategies: improve the financial transfer payment system to ensure the investment of funds; promote the supply side reform of public sports services; break the restriction of administrative regions to integrate the service resources of city group and attach importance to the national physique monitoring work; promote the development of national fitness program.
