摘　　要：基于四阶段DEA模型,测算了我国有色金属-新能源产业链各环节创新效率,并结合Tobit模型检验其影响因素。结果表明:经SFA模型调整,产业链创新效率呈现矿产品>精炼产品>新能源材料>新能源应用的特征,纯技术效率是制约产业链各环节创新效率提升的关键因素;空间上产业链创新效率呈现“西强东弱”的分布特征,产权上国企高于非国企;供应商集中度、企业规模、员工质量与创新效率正相关,市场竞争程度、资产负债率、股权集中度与创新效率负相关。为提升产业链创新效率,应从降低新能源企业创新风险、提高新能源企业收益、推动产业集聚等方面加大政策支持力度。The innovation efficiency of each link of China′s non-ferrous metal-new energy industrial chain was measured based on a four-stage DEA model,and its influencing factors were analyzed with the Tobit model.Based on the study,the following conclusions can be made:after SFA model adjustment,the four links of the industrial chain,i.e.mineral products,refined products,new energy materials and new energy application,can be arranged in descending order in terms of innovation efficiency,and pure technical efficiency is the key factor restricting the improvement of the innovation efficiency of each link of the industrial chain;the innovation efficiency of the industrial chain also presents the characteristics of being stronger in the west and weaker in the east in terms of spatial distribution;state-owned enterprises can demonstrate high innovation efficiency than non-state-owned enterprises;the concentration of suppliers,enterprise size,and the quality of employees are positively correlated to the innovation efficiency,while the degree of market competition,the debt to asset ratio,and the equity concentration are negatively correlated to the innovation efficiency.In order to improve the innovation efficiency of the industrial chain,more efforts should be made in policy support for reducing innovation risks of new energy enterprises,increasing the returns of new energy enterprises,and promoting the formation of industrial clusters.
