对政府资助企业R&D绩效的考察可能由于忽略内生性、行业异质性等而产生偏差。选择2003-2010年上海市大中型工业企业32个行业的面板数据,基于多维行业异质性视角,考察政府R&D资助对企业技术创新的影响。研究表明,政府R&D资助带动了企业R&D投入增长,但直接资助的绩效由于未考虑内生性而被整体高估,并存在较大的行业差异,研发强度越高,企业规模越小,资助绩效越好。而研发强度高、国资比重低的行业具有更高的创新产出效率。
對政府資助企業R&D績效的攷察可能由于忽略內生性、行業異質性等而產生偏差。選擇2003-2010年上海市大中型工業企業32箇行業的麵闆數據,基于多維行業異質性視角,攷察政府R&D資助對企業技術創新的影響。研究錶明,政府R&D資助帶動瞭企業R&D投入增長,但直接資助的績效由于未攷慮內生性而被整體高估,併存在較大的行業差異,研髮彊度越高,企業規模越小,資助績效越好。而研髮彊度高、國資比重低的行業具有更高的創新產齣效率。

The performance of public R&D subsidies may be estimated incorrectly without considering endogeneity and heterogeneity. This paper analyzes the effect of public R&D subsidies on enterprise technology innovation with data of 32 industries in Shanghai during 2003-2010. After dealing with the endogeneity and heterogeneity, the empirical result shows that public R&D subsidies promote the expense of enterprise R&D, but there are signif-icant differences between industries. The existence of endogeneity also leads an overestimate on the performance. Industries with high intensity of R&D and small-scale enterprises perform well on subsidy. And industries with high intensity of R&D and low proportion of state-owned assets do well on innovation.
