本文利用DEA-Malmquist指数法测算了全国服务业14个分行业2003~2009年的TFP增长情况,并且将其分解为技术进步、纯技术效率和规模效率三部分,以研究各个行业的增长路径。实证结果表明,我国服务业整体TFP增长率较高,技术进步较技术效率贡献更大,逐步向集约型增长转变。纵向比较各行业发现,生产性服务行业TFP增长较快,生活型服务行业较慢。
In this paper, we use DEA-Malmquist index method to measure the growth of TFP in 14 sub-sectors of service industry from 2003 to 2009, and divide it into technological progress, pure technical efficiency and scale efficiency to study the growth path of each industry. The empirical results show that the overall TFP growth rate of service industry in our country is higher, technological progress contributes more to technical efficiency and gradually changes to intensive growth. Longitudinal comparison of various industries found that TFP increased rapidly in the producer service industry and that in the lifestyle service industry was slower.
