Key influencing factors of innovation activities in China’s manufacturing enterprises: Evidence from Jiangsu Province

Abstract

Based on empirical evidence from enterprises in Jiangsu Province, this paper studies key influencing factors of their innovation activities at the micro level. Results show that a “threshold effect” and a reversed U-shaped relationship exist between an enterprise’s size and intensity of its innovation input when factors such as brand, entrepreneur background, HR, industrial and regional differences are controlled. Agglomeration effect is found influencing an enterprise’s innovation activities negatively rather than positively. A non-linear relationship is also found between an enterprise’s innovation activities and export ratio, showing a “capture effect”. A behavior mode of the effects of these influencing factors on innovation activities of China’s manufacturing enterprises is established and implications are provided.

摘要

在大量调查问卷基础上, 以江苏省制造业企业为样本, 从微观行为方式层面考察了影响企业创新活动的关键因素。 研究结果表明: 在控制了品牌、 企业家背景、 人力资本、 行业与地区相关因素的前提下, 企业规模与创新投入强度之间呈现较明显的倒U型关系, 而且存在“门槛效应”。 集聚效应在现阶段对企业的创新活动非但没有产生促进作用, 相反产生一定负面影响。 出口因素对企业的创新活动形成了复杂影响效应, 表现在创新活动随着出口比例而发生非线性变化, 呈现出“俘获”效应。 在统计分析的基础上,进一步探讨了企业产品更新与升级换代进程中的关键影响因素和行为模式, 验证了不同规模企业的创新行为特征差异与特有的人力资本竞争机制, 以及它们对企业创新行为的内在作用机理。
