台湾服务业全要素生产率演化及行业异质性研究

Research on Evolution and Industry Heterogeneity of Total Factor Productivity on Taiwan's Service Industry

基于细分行业面板数据,文章运用序列DEA-Malmquist指数模型测算了进入21世纪以来台湾服务业的全要素生产率(TFP)及其分解,并在此基础上,深入剖析台湾服务业全要素生产率的动态演化特征及其增长动力的行业异质性。研究结果表明:台湾服务业的全要素生产率增长已进入下降通道,主要是技术进步增长乏力及技术效率持续恶化所致。从行业视角来看,台湾服务业全要素生产率的增长动力存在行业异质性,其中批发及零售业、运输及仓储业等八个行业的增长动力来自于技术进步;住宿及餐饮业、其他服务业等三个行业来自于技术效率改善;咨讯及通讯传播业、艺术、娱乐及休闲服务业两个分行业由技术进步和技术效率改善共同推动。

Based on the subdivision industry panel data,the paper uses the sequential DEA Malmquist index model to calculate the total factor productivity(TFP)and its decomposition of Taiwan’s service industry in the21st century.This paper analyzes the dynamic evolution characteristics of the TFP and the industry heterogeneity of its growth momentum.The results show that the growth of TFP has declined mainly due to weak growth of technical progress and deterioration of technical efficiency.From the perspective of an industry,the growth power of TFP has industry heterogeneity,specifically,growth in the wholesale and retail trade industry and the transportation and warehousing industry is driven by technological progress;Growth in the accommodation and catering industry is driven by improvements in technical efficiency;Growth in the information and communication industry and the arts,entertainment,and leisure services industry is driven by improvements in both technological progress and technical efficiency.
