生产性服务业与装备制造业的互动发展

The Mutually-Reinforcing Development of Producer Services and Equipment Manufacturing Industry

生产性服务业促进装备制造业发展是工业化进程的必然要求。通过对罗默(1990)"内生技术变动"模型进行拓展分析可知,在均衡状态下作为中间投入部门的生产性服务业的收益递增,能够使得最终生产部门的装备制造业也呈现出收益递增。生产性服务业通过专业分工承接装备制造业的外包,可以降低装备制造业的生产成本和交易成本,同时还可以为装备制造业提供人力资本和其他专业化服务,以提高其生产效率。然而,目前我国的生产性服务业对提高装备制造业生产效率所起的作用较小。因此,我国需要提高生产性服务业的专业化程度,推动装备制造业和生产性服务业的互动发展。

It is the inevitable requirements of industrialization to promote the development of equipment manufacturing industry by producer services.From the analysis on the extended model based on Paul Romer's endogenous technology changes model,we know that increasing returns of producer services as intermediate input sector in equilibrium state may lead to that of equipment manufacturing industry as the final production sector.Production services undertake outsourcing from equipment manufacturing industry through specialization which not only reduces the production and transaction cost but also provides the equipment manufacturing industry with human capital and other specialized services to increase its production efficiency.However,our production services now have little impact on the production efficiency increase of equipment manufacturing industry.Hence,we need to enhance the specialization of production services to facilitate the interactive development of equipment manufacturing industry and production services.
