服务型制造试点政策对企业服务绩效的影响

服务型制造是制造业转型升级高质量发展的重要方向。国家高度重视服务型制造试点工作，推动服务型制造创新发展。现有研究聚焦企业内部因素和外部市场因素对制造企业服务绩效的影响，对试点政策因素的促进作用缺乏关注。以浙江省经济和信息化厅分别于2017和2018年公布的第一、第二批服务型制造试点企业名单为基础，选取包含试点企业在内的浙江省200家具有服务特征的上市制造企业2013-2019年面板数据，通过双重差分分析，检验服务型制造试点政策对企业服务绩效存在的影响。研究发现，服务型制造试点政策的实施对制造企业服务绩效的提升具有显著正向的影响，并且理论上试点带来的企业声誉可能会进一步增强这种提升作用。此外，试点政策对服务绩效的影响存在异质性特征，其净影响随着试点政策的持续而不断加强。具体表现为从试点第一年到试点第三年，企业服务绩效提升速度逐年提高。研究结论有效验证了浙江省服务型制造试点政策实施效果，为我国服务型制造试点政策的制定、实施与改进提供了启示。

The influence of servitization pilot policy on service performance of manufacturing enterprises: An empirical study based on the Difference in Difference model

Servitization is an important direction for the high-quality development of manufacturing transformation and upgrading. The state attaches great importance to the pilot work of service-oriented manufacturing and promotes the innovative development of service-oriented manufacturing. The existing researches focus on the influence of internal factors and external market factors on the service performance of manufacturing enterprises, but pay little attention to the promoting role of pilot policy factors. Based on the list of the first and second batch of service-oriented manufacturing pilot enterprises published by Zhejiang Provincial Department of Economy and Information Technology in 2017 and 2018 respectively, panel data of 200 listed manufacturing enterprises with service characteristics in Zhejiang Province, including pilot enterprises, were selected for 2013-2019. To examine the influence of service-oriented manufacturing pilot policies on enterprise service performance. It is found that the implementation of service-oriented manufacturing pilot policy has a significant positive impact on the improvement of service performance of manufacturing enterprises, and theoretically, the enterprise reputation brought by the pilot may further enhance this improvement effect. In addition, the impact of pilot policies on service performance is characterized by heterogeneity, and its net impact increases with the continuation of pilot policies. The specific performance is that from the first year of the pilot to the third year of the pilot, the improvement speed of enterprise service performance has increased year by year. The implementation effect of the service-oriented manufacturing pilot policy in Zhejiang Province has been effectively verified, which provides inspiration for the formulation, implementation and improvement of the service-oriented manufacturing pilot policy in China.
