中国海洋经济技术进步偏向测度及其空间溢出效应探究

The Measurement of China’s Marine Economy Technology Progress Bias and the Research of Its Space Spillover Effect

为了测算我国海洋经济的要素替代弹性和技术进步偏向,根据标准化供给面系统方法,对我国海洋经济1996-2016年的要素增强型CES生产函数进行估计,并在此基础上采用空间面板杜宾模型进一步探究了技术进步偏向和海洋经济增长的关系。实证结果表明:我国沿海省份的海洋经济的要素替代弹性均小于1,即要素呈现互补的特征,且技术进步均偏向资本。根据空间面板杜宾模型,在海洋经济增长过程中,不仅要关注海洋经济技术进步的资本偏向,也要关注它的资本偏向的空间“扩散”故应,同时也应当格外注意地区开放程度、人乃资本存責以及劳动刀投入等因素对海洋经济的影响。

In order to measure the elasticity of factor substitution and technology progress bias of Chiliad marine economy,this paper estimates China's marine economy factor-augmenting CES production function from 1996 to 2016 by using the normalized supply-side system and spatial panel Durbin model is used to further explore the relationship between the technological progress bias and the growth of marine economy.The empirical results show that:The elasticity of factor substitution of marine economy in China’s coastal provinces is less than 1,which shows the complementary characteristics of the factors,and their technology progress biases are all skewed towards capital.According to spatial panel Durbin model,in the process of Marine economic growth,we should not only pay attention to the capital bias towards technological progress,but also should lay emphasis on its space spillover effect.At the same time,special attention should also be paid to the influence of regional openness,stock of human capital,input of labor and other factors on marine economy.
