我国制造业“四链”协同升级的一个现实途径:服务化转型

Servitization: A Practical Approach to the Coordinated Upgrading of Four Chains in China’s Manufacturing Industry

文章基于“四链”协同升级的视角诠释服务化促进制造业转型升级的机理，运用协调发展系数法测度了2001-2015年我国制造业“四链”协同升级水平，并实证检验了服务化影响“四链”协同升级的效应。研究发现，制造业投入和产出环节服务化水平的提高对“四链”协同升级具有显著正向作用。其中，制造业投入环节服务化水平上升1％，将直接带来“四链”协同升级水平提升0．126％，但是产出环节服务化的影响只有0．079％。此外，夏普利值分解结果表明，服务化投入因素和服务化产出因素对“四链”协同升级水平时空分异的平均贡献度接近15％，且这种贡献度在2005～2015年间呈现逐渐上升的变化趋势。

Based on the perspectives of the coordinated upgrading of the four chains, this paper analyzes how servitization pro- motes the transformation and upgrading of manufacturing. It uses the coordinated development coefficient method to measure the coordinated upgrading of China＇s four chains from 2001 to 2015, and empirically tests the impact servitization has on the coordina- ted upgrading of the four chains. The study finds out that the improvement of the manufacturing input and the service level of the output link have a significant positive effect on the coordinated upgrading of the four chains. For example, a 1% increase in the service level of manufacturing input directly contributes to a 0. 1255% rise in the coordinated upgrading of the four chains, but the contribution of the service of production is only 0. 0792%. In addition, the Shapley value decomposition result shows that the average contribution of the input and output of servitization to the time and space differentiation of the coordinated upgrading of the four chains is close to 15%, and the contribution gradually rose from 2005 to 2015.
