要素价格扭曲、政治关联与中国工业企业的技术创新积极性

Factor Price Distortion,Political Connection and Technological Innovation Enthusiasm of Chinese Industrial Enterprises

作为中国经济转轨时期重要的制度衍生物,要素价格扭曲和企业政治关联对工业企业的技术创新积极性具有重要影响。通过对中国工业上市公司面板数据进行中介效应模型回归,研究发现:中国工业企业存在严重的要素价格负向扭曲,这一要素价格负向扭曲会通过"要素替代效应"直接削弱工业企业的创新积极性,通过提高企业的政治关联主动性对企业的创新积极性产生间接影响;政治关联在要素价格扭曲与工业企业创新积极性之间的"中介效应"存在所有制差异,国有企业中存在"部分中介效应",对要素价格扭曲的创新抑制效应产生负向调节作用,非国有企业中则属于"遮掩效应",即对要素价格扭曲的创新抑制效应存在正向调节功能。

Factor price distortion and political connection are important institutional derivative during the period of Chinese economic transformation. The mediating effect model used to analyze the industrial enterprises listed in Shanghai and Shenzhen shows that serious negative factor price distortion exists in Chinese industry these years,which has directly restrained technological innovation enthusiasm of Chinese industrial enterprises through factor＇ s substitution effect,and the negative factor price distortion has indirect influence to technological innovation enterprises enthusiasm through political connection. The indirect influence of political association to the negative factor price distortion and technological innovation enthusiasm is different in enterprises with different ownership types. In state-owned enterprises,it belongs to ＂the partial mediating effect＂and plays a negative regulatory role in the relation between negative factor price distortion and technological innovation enthusiasm. The indirect influence of political association in non-state-owned enterprises belongs to ＂the shadowing effect＂,so it plays an active role in the relation between negative factor price distortion and technological innovation enthusiasm.
