产业链企业的协同创新网络与创新效率

Collaborative innovation network and innovation efficiency of industrial chain enterprises

针对我国半导体产业形成的产业链企业,使用两阶段网络DEA测度产业链企业的创新效率,以产业链企业协同创新指标为核心解释变量构建回归模型,探究半导体产业链企业协同创新网络对企业创新效率的影响。结果表明:在半导体产业链企业当中,协同创新网络联结强度与企业创新效率负相关,协同创新网络联结强度对企业整体创新效率的正向影响还未发挥出来;产业链企业技术创新阶段效率低于产品创新阶段效率,且企业间联合专利申请数量偏少,产业链企业协同创新主动性偏低;产业链企业协同创新能够有效缓解高技术产业中技术知识外溢,保护创新企业先行优势;从创新两阶段来看,产业链企业协同创新网络联结强度分别与企业技术创新阶段效率、产品创新阶段效率呈倒U型、正U型关系。

For the industrial chain enterprises formed in Chinas semiconductor industry,a two-stage network DEA is used to measure the innovation efficiency of industrial chain enterprises.A regression model is constructed with the collaborative innovation index of industrial chain enterprises as the core explanatory variable to explore the impact of the collaborative innovation network of semiconductor industrial chain enterprises on the innovation efficiency of en-terprises.The results indicate that in semiconductor industry chain enterprises,the strength of collaborative innova-tion network connection is negatively correlated with enterprise innovation efficiency,and the positive impact of col-laborative innovation network connection strength on the overall innovation efficiency of enterprises has not yet been fully realized.The efficiency of the technological innovation stage of industrial chain enterprises is lower than that of the product innovation stage,and the number of joint patent applications between enterprises is relatively small,re-sulting in low initiative of collaborative innovation among industrial chain enterprises.Collaborative innovation a-mong industry chain enterprises can effectively alleviate the spillover of technological knowledge in high-tech indus-tries and protect the leading advantages of innovative enterprises.From the perspective of the two stages of innova-tion,the strength of the collaborative innovation network connection between industrial chain enterprises shows an inverted U-shaped and positive U-shaped relationship with the efficiency of enterprise technology innovation stage and product innovation stage,respectively.Based on empirical results,relevant suggestions are provided for“deplo-ying innovation chains around the industrial chain,laying out the industrial chain around the innovation chain”,and leveraging the leading role of enterprises in the collaborative innovation system:Firstly,we should strengthen the construction of a collaborative innovation network for the chip industry chain,expand the scale of the collaborative innovation network,and increase the liquidity of innovation resources;The second is to diversify the layout of the chip industry chain collaborative innovation network,strengthen technological exchanges between small and medi-um-sized enterprises and leading enterprises,in order to enhance the resource heterogeneity of the industrial chain enterprise collaborative innovation network,and thereby increase the probability of breakthrough innovation in the industrial chain;The third is to build a collaborative innovation network information exchange platform for industrial chain enterprises,in order to reduce governance costs between enterprises and improve resource utilization efficien-cy;Fourthly,strengthen the protection of intellectual property rights in innovation cooperation to reduce collabora-tive innovation risks;Specifically,enterprises should appropriately protect their core technologies during the collab-orative innovation process,and the government should also formulate relevant intellectual property laws and regula-tions to legally protect the technological innovation interests between enterprises and help industries create a good atmosphere of innovation cooperation.Fifth,accelerate the innovation of diversified and intelligent financial tools to hedge the risks of collaborative innovation among industry chain enterprises;Sixth,strengthen market management to combat low-quality imitation and innovation behavior,and provide innovation resource support to small and medi-um-sized enterprises to improve their independent innovation capabilities.According to the phased regression re-sults,in the stage of technological innovation,enterprises should improve the efficiency of innovation resource allo-cation to ensure normal operation of the enterprise;Diversified selection of suppliers and customers to avoid lock-in effects.In the stage of product innovation,it is necessary to be market-oriented,control the product life cycle,im-prove market competitiveness,and reduce losses caused by changes in market demand.
