But it also shows disadvantages in low contribution to national economy and uneven development in internal industries of Chongqing’s producer services. Further quantitative measurement with the use of location quotient indicates that the agglomeration in Chongqing’s producer services and its six representing industries appears urban agglomeration and relatively high level of overall agglomeration. However, the agglomeration in each industry in Chongqing’s producer services presents obvious differences.
