长三角地区服务业生产率变动的测度研究——基于2003—2011年的数据

Measurement of Service Industry Productivity Variation in the Yangtze River Delta Region——Based on the Data from 2003—2011

基于DEA-Malmquist指数法测度研究长江三角洲和上海市服务业全要素生产率(TFP)指数及其增长来源。研究结果表明:长三角地区服务业产出增长率与TFP指数高度正相关,2003—2011年长三角地区服务业TFP指数均值为0.997,而上海市相应指标值为1.023,高于长三角的数值;长三角地区服务业增长趋缓;提升服务业TFP的主要动力是技术进步。长三角地区产业发展逐渐向服务领域转型,应依赖技术创新,鼓励企业研发,促进服务业的长期健康稳定发展。

Based on DEA - Malmquist index method, the paper measures the total factor productivity （TFP） index of serv-ice industry in the Yangtze River Delta region and Shanghai City. The results shows that： growth rate of service industryoutput is highly correlated to TFP index ; TFP index yearly average from 2003 to 2011 is 0. 997, while the number in Shang-hai is 1. 023, higher than the previous figure ; the growth trend of the service industry in Yangtze River Delta region is slo-wer ; technology advancement is a key factor to the increase of TFP index in the service industry. The industry structure inYangtze River Delta region gradually transforms to service economy. In such a process, to increase its productivity and keepa steady healthy development, we should rely on technology advancement and entrepreneurs＇ innovation.
