外资开放、数字信息化与服务化

摘要/Abstract

摘要：

本文依据2007~2016年上市公司年报构建微观层面的服务化指标,从理论和实证两个层面考察外资开放、数字信息化与企业服务化三者之间的关系,得出如下的主要结论:外资开放促进企业服务化;外资开放产生的技术溢出效应有效提高了企业数字信息化水平,进而促进企业服务化;外资开放对产品支持类服务化的边际作用效果大于非产品支持类服务化;外资开放对服务化的作用效果在市场开放程度较高的区域更显著,数字信息化对服务化的作用效果在信息基础设施密度较高的区域更显著。

关键词: 外资开放, 数字信息化, 制造业企业, 服务化

Abstract:

Based on the annual report of listed companies from 2007 to 2016, this paper constructs the servitization index at the micro level, and examines the relationship between opening up of foreign capital, digitization and servitization from the theoretical and empirical levels. The main conclusions are as follows:Opening up of foreign capital promotes servitization. The technology spillover effect produced by the opening up of foreign capital effectively improves the digitization of enterprises and further promotes the servitization of enterprises. The marginal effect of the opening up of foreign capital on servitization of product support is greater than that of non-product support servitization. The effect of foreign capital opening on servitization is more significant in regions with higher degree of market opening, while the effect of digitization on servitization is more significant in regions with higher density of information infrastructure.

Key words: Opening up of Foreign Capital, Digitization, Manufacturing Enterprises, Servitization
