内容提要 | 本文采用全国两次经济普查后的修订数据,运用DEA-Malmquist生产率指数法测算了1990—2010年中国服务业细分行业的全要素生产率(TFP)、技术进步、纯技术效率与规模效率增长率。结果表明,中国服务业总体及细分行业的TFP均处于上升通道,以2002年为界,前期导致服务业分行业TFP增长的主导因素是技术效率改进,后期主要是技术进步提高,且技术效率改进已开始由以纯技术效率为主转向以规模效率为主,但服务业发展的粗放型特征仍然明显。同时,中国服务业TFP增长表现出了较大的行业异质性,与工业行业对比,服务业TFP增长率是滞后的。2010年与1991年相比,TFP和技术效率的行业间异质程度有所下降,而技术进步却有进一步拉大的迹象。可能的内在机制是现代信息技术对不同服务业企业资源配置的异质影响,以及中国服务业体制改革的渐进式道路。 |
Abstract | Using the revised data by National Bureau of Statistics according to the first and second economic census and the method of DEA-Malmquist Productivity Index, this paper measures the total factor productivity (TFP) and its decompositions in China's service industries from 1990 to 2010. The results show that the service TFP in overall level and sub-industry level are all rising, and the turning point appears in 2002 before which the dominant factor leading to TFP growth is technical efficiency improvements, while technical progress becomes the dominant factor after 2002. Meanwhile, the heterogeneous phenomenon exists in China's service TFP growth, and the growth rate of service TFP is lagging behind that of industries. From 1991 to 2010, the inter-industry heterogeneity of technical efficiency and TFP has declined, while technological progress is widening. Possible mechanisms are the heterogeneous effects of modern information technology on the resource allocation of different service firms and the gradual road of service industries’ institutional reform in China. |
