摘要/Abstract

摘要： 当前中国企业创新活动的持续性面临内外部环境变化的重大挑战,且现代经济的生产和分工越来越趋于网络化,利用企业贸易网络破解企业创新困境成为新发展阶段中国创新增长的重要战略支撑。首先构建一个企业贸易网络与同伴创新博弈模型,然后基于2009—2013年中国上市公司的供应商-客户贸易网络数据进行实证检验,研究企业与上下游伙伴形成的企业贸易网络中的创新同群效应。研究发现,企业贸易网络中同伴企业的技术改进显著促进了企业创新,即企业贸易网络中存在创新同群效应,且垂直同伴的主要作用渠道是知识溢出,而水平同伴的主要作用渠道是竞争压力。进一步研究表明,企业贸易网络中的创新同群效应具有高阶性质,且在供应商垂直同伴样本和共享客户水平同伴样本中更显著,并随市场化程度的提高而增强。因此,要合理布局企业贸易网络,确立竞争和市场机制在资源配置中的主导作用,关注政策的网络溢出效应,以实现由“中国制造”向“中国创造”的成功转型。

Abstract: Nowadays, the persistence of the innovation activities of Chinese firms is faced with severe challenges from both internal and external environmental changes. And the production and the division of labor in the modern economy are becoming more and more networking. As a result, using the enterprise trade networks to solve the innovation dilemma has been an important strategy to achieve the objective of innovative growth in China’s new development stage. This paper first constructs a model of enterprise trade network and peer innovation game, then it conducts an empirical test based on the supplier-customer trade network data of China’s listed companies from 2009 to 2013, so as to study the innovative peer effects in the enterprise trade network formed between the enterprises and their upstream and downstream partners. The findings show that the technological improvements of the partner enterprises in the enterprise trade networks have significantly promoted enterprise innovations, namely, there exist innovation peer effects in the enterprise trade networks. The major channel affecting the vertical partners is knowledge spillover, while the major channel affecting the horizontal partners is the competitive pressure. Further study reveals that the innovation peer effects in the enterprise trade networks have the high-order property, which is more significant in the samples of supplier vertical partners and in the samples of the horizontal partners of the shared customers, and that these effects will be enhanced with the improvements of the degree of marketization. Therefore, we should properly distribute the enterprise trade networks, establish the leading role of competition and market mechanism in resource allocation, and pay attention to the network spillover effects of related policies, so as to achieve the successful transformation from China-made to China-created.
