服务业各行业生产率变迁与内部结构异质性

Productivity Change and Internal Structural Heterogeneity in China's Service Sub-industry

运用超越对数生产函数的随机前沿模型测度1990年以来中国服务业各细分行业生产率及技术状况,采用DFA分析中国服务业内部结构演化及各行业发展异质性。研究表明,技术进步是目前推动我国服务业向集约化经济发展的主导力量,技术效率的改进是主导TFP变化的核心因素;生产性服务业技术进步对产值贡献度较大,并且其技术效率要高于生活性服务业;服务业内部结构演化存在明显异质性,新型生产、生活性服务业随着经济发展水平的提高形成和不断发展,消费资料型服务发展逐渐壮大。

The paper uses Translog Stochastic Frontier model to give an analysis on pro- ductivity and technical development for China＇s service sub-ndustry from 1990 to 2012. Then it uses Dynamic Factor Analysis method to give a comprehensive assessment for the internal structural evolution and it＇s heterogeneity. The results show that. technical progress is the leading force to push forward the intensive development of China＇s service economy. The technical efficiency improvement is the core of the total factor productivity. The technical progress of producer service has a big contribution on output, and it＇s technical efficiency is higher than consumer service. There is an obvious heterogeneity in service industry＇ internal structural evolution. The new service such as productive service and consumer service will form and continual to develop, the consumer service enlarge gradually.
