中国技术进步偏向性的省际扩散效应:1996-2015

本文通过构建理论模型,在发达经济体的要素增强型技术向欠发达经济体进行扩散的假设下,发现技术进步偏向性也会呈现出从发达经济体向欠发达经济体扩散的现象.文章利用中国30个省区的相关数据,测算了不同地区的技术进步方向指数,并进一步利用该指数考察各省区技术进步偏向性与北京,上海,广东这三个经济发达省区技术进步方向的关系.研究发现,北京,上海的技术进步方向对其他各省区的技术进步偏向性存在显著的同向影响关系,而广东的影响并不显著.进一步的研究还发现,中国存在着资本增强型技术和劳动增强型技术从北京,上海向其他各省区的扩散效应,这也从实证上验证了理论模型中的假设,一定程度地揭示了技术进步方向存在扩散效应的机制.

The diffusion of the directed technical change among China's provinces: 1996-2015

Through constructing theoretical model and under the hypothesis that the factor enhanced technology will diffuse from developed area to developing area, this article analyses the diffusion effects of directed technical change from developed area to developing area. This article measures the 30 Chinese provincial directions of technical change in 1996-2015 and analyses the diffusion effects from Beijing, Shanghai and Guangdong to other provinces empirically. This research indicates that Beijing's and Shanghai's directed technical change has positive relationship with other provinces'. This article also indicates that the diffusion effects of the factor enhanced technology from Beijing and Shanghai to other provinces are existed and verifies the hypothesis in the theoretical model.
