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。

A crucial debate between Romer(1990) and Jones(1995) is centered on whether there is scale-effect or not in knowledge production process. This paper estimates the scale-effect of the knowledge production of innovation economy sector of NHIDZ by using panel data method. We find that the stock of knowledge and human capital play significant role in the knowledge production process, and the output elasticity with respect to the stock of knowledge is around 0.89-0.97, the output elasticity with respect to human capital is around 0.52-0.64.The sum of the output elasticity of the stock of knowledge and human capital is significantly greater than 1, indicating that the knowledge production of innovation economy sector of NHIDZ does have scale-effect to the existing stock of knowledge and human capital，and the facts support the Romer-type knowledge production function. This finding can be useful for the making of innovation policy.
