摘　　要：本文基于中国制造业上市公司2003-2012年的面板数据,利用Wooldrige(2005)提出的动态随机效应Probit估计模型,实证检验企业是否存在创新持续性,并进一步考察了企业持续创新的决定因素。实证结果表明:(1)中国制造业企业存在持续创新,企业规模,经营年限,资本密集度以及利润对企业的持续创新影响显著。(2)将全部制造业企业分为高技术机会群体(高新技术企业)和低技术机会群体(非高新技术企业),高新技术企业和非高新技术企业都存在创新持续性,但前者创新持续性要强于后者,前者更多依靠企业的利润积累增加研发支出从而维持创新持续性,后者更多的是依靠规模经济的优势来维持创新的持续性。Based on a panel data of China's manufacturing firms over the period of 2003-2012,weuse the dynamic random effects probit model which is put forward by Wooldrige(2005). This paper studies whether the company exits the persistence of innovation and determinants of the persistence. The empirical results show that:(1) China's Manufacturing Firms exit the persistence of innovation. Andfirms' size,age,capital ratio and profit have significant effects on the persistence of innovation.(2) Manufacturing firms can be divided into high technological opportunity group(scientific industries) and low technological opportunity group( nonscientific industries),all of them exit the persistence of innovation,and however,persistence effect of scientific industries is much higher than it of non-scientific industries. The former increases spending on research and development fee,largely relying on profit accumulations of company to maintain the persistence of innovation,while the latter relies on the advantage of economies of scale to maintain it.
