制造业服务化对生产性服务业效率的影响——基于面板数据动态GMM和SFA方法的实证分析

The Influence of Manufacturing Serivice on the Efficiency of Producer Service——Empirical Analysis of Dynamic GMM and SFA Methods Based on Panel Data

本文基于全球42个国家15年的面板数据,采用动态GMM和随机前沿分析方法(SFA)分析了制造业服务化对生产性服务业效率的影响。分析结果显示,在制造业服务化水平方面,发达国家略领先于发展中国家,在生产性服务业效率方面,发达国家远超于发展中国家。进一步发现制造业服务化对生产性服务业效率的影响是滞后的,其对生产性服务业效率的影响随时间由正转负。制造业服务化对中低端生产性服务业效率的提升作用相对较强,当期的制造业服务化只对发达国家生产性服务业效率有正向影响。本文的研究成果对推动我国两业融合发展,促进制造业高质量发展具有一定的启示作用。

Based on the 15-year panel data of 42 countries,this paper analyzes the impact of manufacturing service on producer service efficiency by dynamic GMM and stochastic frontier analysis(SFA).The results show that the developed countries are slightly ahead of the developing countries in terms of the service level of manufacturing,and the developed countries are far more efficient than the developing countries in terms of producer service.The impact of manufacturing service on producer service efficiency is lagging behind,and its impact on producer service efficiency changes from positive to negative over time.Manufacturing service has a strong effect on the efficiency of low-end producer services,and the current manufacturing service only has a positive impact on the efficiency of producer service in developed countries.The research results of this article have a certain enlightenment effect on promoting the integrated development of the two industries in our country and promoting the high-quality development of the manufacturing industry.
