摘要: 依据创新价值链理论的分析可以看出,我国高技术产业创新是一个多投入、多产出、多环节的活动,根据高技术产业的自身特点,高技术产业创新活动可分为技术开发环节和技术成果转化环节,通过运用DEA模型对技术开发环节和技术成果转化环节的创新效率进行测算,同时构建地理距离空间权重矩阵,运用空间误差模型对技术开发效率和技术成果转化效率的外溢效应进行实证研究,可得到以下几点结论:我国高技术产业创新活动存在技术开发效率较高而技术成果转化效率较低的问题;同时,无论是技术开发效率还是技术成果转化效率都不完全与当地经济发展水平相一致,一些中西部省份创新效率也较高。在我国高技术产业各环节创新效率的空间外溢效应方面,技术开发效率与技术成果转化效率均存在显著的空间外溢效应;而在价值链外溢效应方面,技术开发效率与技术成果转化效率之间不存在显著的价值链外溢效应。

Abstract: Hightech industry innovation in China involves multiinput, multioutput and multilink activities according to the theory of innovation value chain. Innovation activities consist of technology development and technology achievement transformation,judging by the characteristics of the industry. In this study, innovation efficiency of technology development and technology achievement transformation is calculated by using DEA model, the spatial weight matrix of geographic distance is constructed, and the spatial error model is used to analyze the spillover effect.The results show that: innovation activities of hightech industries in China have low efficiency in technology achievement transformation despite high efficiency in technology development.In addition, neither the efficiency of technological development nor the efficiency of transformation of technological achievements is in full agreement with the level of local economic development since the innovation efficiency in some central and western provinces is considerably high. There are significant spatial spillover effects in the efficiency of technological development and technological achievements transformation in all sectors of China's hightech industry while there is no significant value chain spillover effect between technology development efficiency and technology achievement transformation efficiency.

Key words: innovation value chain, hightech industries, innovation efficiency, spillover effect
