研发投入、创新网络与战略性新兴产业赶超发展

研发投入与战略性新兴产业赶超发展之间存在非线性关系，是因为受到了创新网络效率的影响。这是因为，一方面，创新是一个非线性、联动的系统工程，创新效率的提高不仅是创新个体努力的行为，更是创新生态系统内各要素共同作用的结果。另一方面，创新网络的构建能够提升创新主体吸收、获取、利用资源的能力，提高研发投入资源优化配置水平，能够将研发投入资源有效转换为推动战略性新兴产业赶超发展的动力源。当前，我国大部分地区创新网络效率不高，创新网络效率对研发投入驱动战略性新兴产业赶超发展具有单一门槛效应。在创新网络效率较低的地区，加大研发投入并不能有效推动战略性新兴产业赶超发展，表现出“高投入、低效率”的特征。在创新网络效率较高的地区，增加研发投入能够高效转化为技术成果和经济效益，表现出“高投入、高效率”的特征。因此，应推动战略性新兴产业技术创新的路径从“投入导向型”向“效率导向型”转变，从制定有效的激励机制、升级创新载体和平台、构建协同创新体系、着力培养科技中介服务组织等方面提升创新网络效率。

Research and Development Investment,Innovation Network and the Catch-up Development of Strategic Emerging Industries

There is a non-linear relationship between research and development (R & D) investment and the catch-up development of strategic emerging industries,which is affected by the efficiency of innovation network.This is because,on the one hand,innovation is a nonlinear and linkage system engineering,and the improvement of innovation efficiency is not only the behavior of individual innovation efforts,but also the result of the joint action of various elements in the innovation ecosystem.On the other hand,the construction of innovation network can enhance the ability of innovative subjects to acquire,absorb and utilize resources,improve the level of optimal allocation of R & D investment resources,and effectively transform R & D investment resources into a power source to promote the development of strategic emerging industries.At present,the efficiency of innovation network in most parts of China is not high,and it has a single threshold effect on the development of strategic emerging industries driven by R & D investment.In the areas with low efficiency of innovation network,increasing R & D investmentcan not effectively promote the development of strategic emerging industries,showing high investment and low efficiency.In the areas with high innovation network efficiency,increasing R & D investment can be efficiently transformed into technological achievements and economic benefits,showing high investment and high efficiency.Therefore,the path of technological innovation in strategic emerging industries should be transformed from input-oriented to efficiency-oriented.The efficiency of innovation network should be improved from the aspects of effective incentive mechanism,upgrading innovation carrier and platform,building collaborative innovation system,cultivating science and technology intermediary service organizations and so on.
