不同行业以及创新投入的不同内容(产品创新投入和工艺创新投入)对于企业绩效的影响是有差异的,且存在滞后性。文章以两个技术水平不同的行业——信息技术业和制造业的企业为研究样本,选取2010—2014年的工艺创新投入、产品创新投入和企业绩效的相关面板数据并分别进行相关性分析。研究表明:第一,信息技术业产品创新投入与企业当期绩效存在显著关系,而工艺创新投入与当期企业绩效关系不显著;相反,在制造业中,产品创新投入与企业当期绩效不存在显著关系,而工艺创新投入对企业当期绩效存在显著正向影响。第二,信息技术业的产品创新投入对企业绩效的影响存在滞后性,滞后期为三年。制造业的工艺创新投入对企业绩效的影响存在滞后性,滞后期为2年。上述研究结果进一步验证了“A-U”模型。
Different industries and different aspects of innovation investment (investment in product innovation and process innovation) have different impacts on business performance, and there are lags behind. The article takes two industries with different skill levels - information technology and manufacturing enterprises as the research samples, and selects the related panel data of process innovation investment, product innovation investment and business performance from 2010 to 2014, and respectively analyzes the correlations. The research shows that: Firstly, there is a significant relationship between the input of product innovation in the information technology industry and the current performance of the enterprise, while the input of technology innovation is not significantly related to the performance of the current enterprise; in contrast, in the manufacturing industry, there is no significant relationship between the input of product innovation and the current performance of the enterprise , While the investment in process innovation has a significant positive impact on the current performance of the enterprise. Second, the impact of product innovation investment in information technology industry on the performance of enterprises lags behind, lagging for three years. The impact of manufacturing innovation inputs on business performance is lagging behind with a lag of two years. The above findings further validate the “A-U” model.
