为全面解析服务业产出占GDP比重以及服务业投资总额持续增长背景下的投资是否具有效率,本文利用史实数据构建了1985-2011年服务业投资、产出、就业人数、工资收入、城镇化率等一系列指标,并采用2003-2010年间的省级面板数据进行了回归分析。研究结果表明:和一、二产业相比,服务业具有极高的资本消耗率,其中交通运输、仓储和邮政业与房地产业的投资效率最低。就区域差异而言,与中西部相比,我国东部地区的服务业投资效率最高。造成这一现象的原因既有核算制度的缺陷,也有现行区域经济发展不平衡的原因,同时也有行业自身的特点和现行体制的阻碍。
In order to comprehensively analyze whether the output of service industry accounts for the GDP and the investment in the service industry continues to grow, whether the investment is efficient or not, this paper builds the data of service investment, output, employment, wage income, urbanization Rate and a series of indicators, and the use of provincial panel data during 2003-2010 regression analysis. The results show that: Compared with the primary and secondary industries, the service industry has a very high rate of capital consumption, of which transportation, storage and postal industries and real estate investment efficiency is the lowest. In terms of regional differences, compared with the central and western regions, service investment in the eastern region of China is most efficient. The reason of this phenomenon is not only the defects of the accounting system, but also the reason of the unbalanced regional economic development, as well as the industry’s own characteristics and the obstacles of the current system.
