本文在城市经济学理论的基础之上，尝试性地提出生产性服务业集聚的理论框架，并以全国247个城市的面板数据进行实证检验。理论分析表明，本地市场规模、工业企业平均规模（需求因素）以及交易成本、生产性服务业的专业化程度与竞争程度（供给因素）等因素共同促使了生产性服务业的集聚。实证检验证实，虽然生产性服务业主要集聚于具有较大市场规模和更优经济地理位置的中心城市，但我国不同区域引致生产性服务业集聚的关键性因素存在差异，东部城市表现为本地市场规模，而中西部城市则是交易成本。实证结果还表明，规模大的工业企业具有明显的服务外包化倾向；同时生产性服务业存在MAR溢出，专业化有利于提高集聚度。为此，本文提出了加快生产性服务业聚集的政策建议。

Based on Urban Economic Theory, this paper tries to build a theoretical framework of producer services agglomeration and to conduct an empirical test by using panel data of 247 cities across the country. Theoretical analysis shows that the size of local market, the average size of industrial enterprises （demand factors） as well as transaction costs, the degree of specialization of producer services and the level of competition （supply factors） promote the agglomeration of producer services. Empirical test confirms that although producer services concentrate in the central cities which have a larger market size and better economic geographical location, the key factors in the agglomeration of producer services in different regions of our country are different： for the eastern city the key factor is the local market scale, while the key factor for central and western cities is transaction costs. The empirical results also show that large-scale industrial enterprises are tend to outsource services and there exists MAR spillover in producer services, so the specialization helps to improve the degree of concentration. To this end, this paper proposes policy recommendations to speed up the producer services agglomeration.
