This essay employs quantile regression and uses the firm data of communications equipment manufacturing, to explore the determinants of the spatial pattern of heterogeneous firms. The main results are: first, the larger the market potential, the more possibility of the lower average productive performance. Second, the investment on infrastructure plays more important role than subsidy spending in boosting the development of firms of communications equipment manufacturing. Meanwhile, development area policy has positive effects on attracting high-productive firms. Third, firms of low productivity more rely on rich labor source, while those of high productivity prefer to environment of research. Finally, the middle and west regions have less attractions. The suggestion is to transfer the development mode that only focuses on the size of industry and to cultivate high quality firms.
