在中国各省区服务业的历史统计数据基础上,采用随机前沿分析(SFA)方法,对各省区及东、中、西部三大区域的服务业技术效率进行了测度,分析了中国及三大区域服务业存在的技术效率差异及其变化趋势,结果表明:在全国范围内,服务业技术效率存在着差异;在三大区域内,东部各省区的服务业技术效率差距最大,中部各省区的服务业技术效率差距适中,西部各省区的服务业技术效率比较均衡,差距最小;无论是全国还是三大区域,不同省区间服务业技术效率的差异都在逐渐减小,并有趋同趋势。
Based on the historical statistics of service industries in all provinces and autonomous regions in China, this paper uses the stochastic frontier analysis (SFA) method to measure the technical efficiency of service industries in three provinces, including the three provinces in the east, middle and west regions of China, The results show that there are differences in the technical efficiency of service industries across the country. Within the three regions, the technical efficiency of service industries in eastern provinces is the most disparity, and the service of the central provinces and autonomous regions The technological efficiency of industry is moderately disproportionate, and the technical efficiency of service industries in the western provinces and regions is relatively balanced with the smallest disparity. The technological efficiency of service industries in different provinces and autonomous regions is gradually decreasing and there is a trend of convergence both in the whole country and in the three major regions.
