The new production function has follow properties:the production function has constant returns to scale;the marginal rate of technical substitution and the elasticity of substitution are only related to the ratio of the two elements;the production function satisfies the Euler Theorem.
将经典的柯布-道格拉斯生产函数进行改型,得到一种生产要素间相互制约的新的生产函数,并对函数进行纯粹数学意义上的推导,得到该函数具有的一些经济性质:1)规模报酬不变;2)两要素间的技术替代率和替代弹性仅与两要素的投入比率有关,而与投入量无关;3)产品对生产要素的分配满足欧拉定理。
We find higher-concentration industry and low-concentration industry have significant difference with the technique characteristics of industries: average scale has significant positive effect to the market concentration of high-concentration industry,but it has significant negative effect to low-concentration industry.
通过运用两类产业的面板数据模型,笔者发现高集中度产业和低集中度产业与产业的技术特征之间的关系有着显著的区别:平均规模对高集中度产业的市场集中度有着显著正影响,而对低集中度产业的市场集中度有着显著负影响;两类产业的技术替代率对市场集中度的影响也不相同,其中高集中度产业的边际技术替代率对市场集中度的影响并不显著。
