技术创新对于能源效率的提高具有复杂影响,不同类型的技术创新行为与能源效率的相关性具有差异性,由于回报效应的存在,企业原始创新和二次创新策略提高能源效率的力度和路径截然不同。本文通过建立企业技术创新策略的斯塔克伯格模型,分析了贯序性企业技术创新行为对能耗水平的影响,并利用非参数统计方法对两类技术创新策略与能源效率的相关系数差异性进行了检验。结论表明:(1)中国工业行业的企业原始创新行为与能源效率具有微弱的正向关系;(2)中国工业行业的企业二次创新行为与能源效率具有较强的正向关系;(3)技术创新对于能源效率的回报效应主要体现在原始创新活动上。
Technological innovation has a complex impact on the improvement of energy efficiency. There are differences in the correlation between different types of technological innovation and energy efficiency. Because of the return effect, the intensity and path of enterprise original innovation and secondary innovation to improve energy efficiency are very different . In this paper, through the establishment of Starkberger model of enterprise technology innovation strategy, this paper analyzes the impact of technological innovation behavior of sequential enterprise on energy consumption level, and uses non-parametric statistical method to analyze the difference of correlation coefficient between two types of technology innovation strategy and energy efficiency Sexuality was tested. The conclusions are as follows: (1) There is a weak positive relationship between original innovation behavior and energy efficiency in China’s industrial sector; (2) there is a strong positive relationship between secondary innovation behavior and energy efficiency in China’s industrial sector; (3) The return effect of technological innovation on energy efficiency is mainly reflected in the original innovation activities.
