A Carrier-Load Perspective Method for Investigating Urban Public Service Carrying Capacity
To accurately measure urban public services carrying capacity(UPSCC)is an important basis for alleviating the contradiction between public services supply and demand and promoting sustainable urban development.Based on the perspective of"carrier-load",this study proposes a method for UPSCC measurement based upon the matching state of public service carrier and load.In order to verify the validity of the proposed method,41 cities in the Yangtze River Delta region are selected to carry out an empirical study.The main conclusions are as follows:(1)UPSCC refers to the strength that carrier carrying the load,which can be expressed as the bearing state value.The optimal value is not necessarily the largest or smallest,but rather a reasonable one that aligns with the city's specific development conditions.(2)The state value of UPSCC has interval characteristics,which can be divided into four intervals by quartile method,namely high-risk overload interval,high utilization interval,moderate utilization interval and low utilization interval.(3)The empirical analysis shows that the interval of UPSCC in the Yangtze River Delta region has gradually changed from high-risk overload and high utilization to moderate utilization and low utilization,and the overload risk has weakened year by year.
