中国制造业企业R&D行为模式的观测与实证——基于江苏省制造业企业问卷调查的实证分析

An Observation and Empirical Study of R&D Behavior of Chinese Manufacturing Firms:Based on a Survey of the Manufacturing Firms in Jiangsu Province

本文在大量调查问卷的基础上,以江苏省制造业企业为样本,以统计实证与计量分析等方法考察与观测企业所处行业、企业规模以及企业所有制等三个因素对企业R&D行为的影响,从微观行为数据层面揭示了中国制造业企业R&D活动的行为模式与真实机理。论文的许多发现为理解R&D“不易观测”的关键因素提供了基于中国经验的独特的实证视角。我们揭示出:中国小公司、中型公司、大公司的R&D强度趋势存在着明确的倾斜的V型结构关系,以此修正了Bound等、Pavitt等人的理论观点。

Based on the samples of the manufacturing firms in Jiangsu Province, this article observed and analyzed in an empirical and statistical way the influence from industry, firm size and ownership on R＆D behavior. By this, we discovered the real mode and the underlying mechanisms of R＆D behavior on the firm level. All these discoveries provided a unique empirical prospect for understanding the ＂unobservable＂ key factors of R＆D determinants based on the Chinese experience. We found out a clearly inclined-V-shaped trend of R＆D intensity among firms of different sizes and, therefore, amended several conclusions of Bound, Pavitt and other scholars.
