中文摘要：

服务业城市集聚效应本质上是一个产业效应扩散的衍生现象，尽管服务业集聚效应本身并不构成问题，但服务业集聚效应传导的渠道背离使城市产业政策扶持缺乏依据，服务业集聚效应的差异必将导致城市经济发展的差别。基于此，本文从服务业集聚的影响因素出发，探讨了服务业城市集聚的原因，并以纽约和东京为例对服务业城市集聚的内在机理进行了实证检验，最后在相关研究结论的基础上给出我国制定服务业集聚发展战略的政策思路。

英文摘要：

The endogenous interaction of services agglomeration in urban is a derivative phenomenon of industry spread effect in essence. Although services agglomeration effect itself is not a problem, Channel departure from Services agglomeration effect makes industrial policy lack of basis. Then services agglomeration effect differences will lead to urban economic development lags behind. Based on this, this article, based on the influence factors of the services agglomeration, probes into the reasons of services agglomeration in urban, and carries out an empirical test of the inner mechanism of services agglomeration in urban as examples of with New York and Tokyo. Moreover, this article, based on related research conclusions, provides policy ideas of making services agglomeration development strategy in our country at last.
