服务行业相对制造行业具有更高的平均获利能力。本文首先构建了一个两阶段成本节约型创新博弈模型，得出技术型服务企业高获利能力主要来自于企业的研发创新，而不是其市场势力的理论假说。通过运用60家技术型服务上市公司截面数据的实证检验，发现研发创新与技术型服务上市公司的高获利能力有显著的正相关关系，而市场势力与技术型服务上市公司的高获利能力有显著的负相关关系，服务企业还没有形成普遍的市场势力，企业在位时长、企业规模并不是服务企业市场势力的主要决定性因素。因此，技术型服务企业应该走创新发展战略，不要盲目追求市场垄断势力。

Service industries have higher average profitability than that of manufacturing sectors. This paper firstly builds a two-stage game model of cost-saving innovations and makes the theory hypothesis that the technical service industries＇ high profitability mainly comes from the R~-D of corporations, rather than their market power. The empirical test results show that there is a significant positive correlation between RInD and high profitability, but a significant negative correlation between market forces and high profitability by using the cross-sectional data of 60 technology-oriented service Listed companies. Service companies have not formed universal market forces. Firm size and life are not the primary determining factors of market power. So, the technology-oriented enterprises should pursue the innovation developmental strategy, not the market power blindly.
