影响高技术产业创新绩效的因素有多种,从全国层面看,专业化有负向的影响,多样化有正向的影响;但从分地区来看,虽然专业化仍是负向影响,但多样化对创新绩效影响由于受到企业规模等控制变量的约束呈现东中西部不同的特征,东部为正,西部不显著,中部为负。在控制变量的影响方面,公路里程等交通设施、人力资本投入、技术人员投入比例等对创新产出有正的影响;企业规模在东部地区有负的影响,中西部为正的影响;创新投入则影响为负。
There are many factors that affect the innovation performance of high-tech industries. From a national perspective, specialization has a negative impact and diversification has a positive impact. However, although specialization still has a negative impact from different regions, The impact of diversification on innovation performance is different due to the control variables of firm size and other characteristics of the eastern, central and western regions. The eastern part is positive, the western part is not significant and the middle part is negative. In terms of the influence of control variables, the transportation facilities such as highway mileage, human capital investment and the ratio of technical personnel input have a positive impact on the output of innovation; the scale of enterprises has a negative impact in the eastern region and a positive impact in the central and western regions; and innovation inputs The effect is negative.
