科技服务渗透对制造业技术进步的影响——基于世界投入产出表的经验证据

The Influence of Science and Technology Services Penetration on the Technological Progress in Manufacture——Empirical Evidence from Updated World Input and Output Table

利用世界投入产出表计算制造业细分行业科技服务渗透指数,在此基础上实证分析科技服务渗透对制造业技术进步的影响。结果表明:科技服务渗透促进了制造业技术进步,但作用强度不尽如人意;科技服务业的创新贡献在不同要素密集型制造业差异较大;本土科技服务与进口科技服务对制造业创新绩效都具有显著激励作用,且前者比后者的创新促进效应更显著;科技服务对制造业的创新激励存在明显的本地化效应,本土科技服务与进口科技服务在制造业创新过程中存在互补促进作用,需要进一步强化本土科技服务对进口科技服务的消化吸收再利用能力。

Based on manufacturing industry panel data of the latest world input-output table,this paper calculates science and technology services penetration index of Chinese manufacture subsector,and then empirically analyzes the impact of science and technology services penetration on manufacturing technology progress.Results indicates:science and technology services penetration has promoted the technological progress of manufacturing industry in China,but the strength of the effect is not satisfactory;innovation contribution of science and technology services is differently in factor-intensive manufacturing industry;both local and imported science and technology services have significant stimulating effects on manufacturing innovation performance,the former have stronger promoting effect on the innovation than the latter,while are obvious that local science and technology services have localization effects;there is complementarity between local and imported science and technology services in the process of manufacturing innovation.Imported science and technology services can promote the development of local science and technology services,which mean that local science and technology services need to further absorb and reuse the capacity of imported science and technology services.
