本文以Romer(1990)和Jones(1995)关于知识生产是否存在规模递增效应之争为研究出发点,运用我国53家国家级高新区2005年-2012年的数据,采用面板回归分析的方法实证检验高新区这种创新经济体的知识生产是否存在规模递增效应。结果表明,我国高新区在知识生产过程中,知识存量和人力资本发挥了显著作用,知识存量投入的产出弹性在0.89-0.97之间,人力资本投入的产出弹性在0.52-0.64之间,二者产出弹性之和显著大于1,显示出了很强的规模递增效应,说明创新经济体的知识生产支持Romer(1990)类型的知识生产函数。该结论对于国家制定创新驱动发展的相关政策具有重要的现实意义。
This paper takes Romer (1990) and Jones (1995) as the starting point to study whether there is scale increasing effect in knowledge production. Using the data of 53 state-level high-tech zones in China from 2005 to 2012, using panel regression analysis, Whether there is an increasing scale of knowledge production in a region like this innovative economy. The results show that in the process of knowledge production, the high-tech zones play a significant role in knowledge production and human capital. The output elasticity of knowledge stock inputs is between 0.89 and 0.97, and the output elasticity of human capital inputs is between 0.52 and 0.64. The sum of their output elasticity is significantly greater than 1, indicating a strong scale-up effect, indicating that knowledge production in innovative economies supports the Romer (1990) type of knowledge production function. This conclusion is of great practical significance for the country to formulate the policy of innovation-driven development.
