家庭能效政策的节能创新效应:中国数据的实证

Technological Innovation Effects of Household Energy Efficiency Policies:An Empirical Study of Chinese Data

目前关于节能创新诱导效应的研究主要集中在能源供应方面,很少关注家庭部门能效政策的创新效应。基于中国数据,搜索整理了1996-2017年间的政策信息和22个行业专利数据,并利用泊松回归方法着重研究家庭部门能效政策与节能创新效应之间的关系。研究发现:(1)家庭需求拉动型政策具有较为显著的节能创新效应;(2)将工业和家庭能效政策组合成政策体系时会产生更大的节能创新效应;(3)家庭需求拉动型政策节能创新效应具有较为显著的异质性。

At present,research on the induced effect of energy-saving innovation mainly focuses on energy supply with little attention on the innovative effects of energy efficiency policy in the household sector.Therefore,based on Chinese data,the study sorts out the policy information and 22 industry patent data from 1996 to 2017,and uses the Poisson regression method to focus on the relationship between the energy efficiency policy in household sector and energy-saving innovation effect.The study found that:(1) the household sector demand-pull policy has a significant energy-saving innovation effect;(2) the energy efficiency policy in industrial and household sector can be combined into a policy system to produce greater energy-saving innovation effects;(3) The energy-saving innovation effect of the demand-pull policy in the households sector has obvious heterogeneity.
