高新技术企业内外投入的互补与替代效应研究——吸收能力的调节作用

Research on the complementary and substitution effect of internal and external input in High and new technology enterprise——Absorptive capacity adjustment

摘要:

构建超越对数的知识生产函数,从理论上分析内外创新投入的互补与替代效应、及其关键影响因素；收集高新技术企业2000-2014年内外创新投入产出相关的面板数据,运用计量模型对相关理论进行了实证检验。发现：(1)在无内部吸收能力调节作用的条件下,内外创新投入对研发与商业化阶段的产出具有替代性。(2)在有内部吸收能力调节作用的条件下,内外创新投入对研发与商业化阶段的产出具有互补性。(3)吸收能力对内外创新投入的互补效应有显著的调节作用。在此基础上,提出了提升我国高新技术企业创新绩效的针对性建议。

Abstract:

Building beyond the logarithmic knowledge production function, theoretically analyzing complementary and alternative effect of the internal and external innovation and the key factors influencing; Collecting panel data related to the internal and external innovation input and output during 2000-2014 in high and new technology enterprises, using the econometric model, the empirical test has been carried on the related theory. found: (1) In the absence of internal adjustment of absorptive capacity ,the internal and external innovation input has alternative effect to the output of R D and commercialization stage .(2) Under the condition of internal absorption ability regulation, the internal and external innovation input has complementary effect to the output of R D and commercialization stage (3) absorptive capacity has a significant adjustment to the complementary effect of the internal and external innovation input. Based on this, the paper proposes policy recommendations to improve innovation performance of high and new technology enterprises in China effectively
