互联网应用与我国技术进步的要素偏向

Internet Application and the Factor Bias of Technological Progress in China

互联网的发展和普及极大地改变着我们的生活,也改变着产业与企业层面技术进步的偏向。本文借助已有技术进步偏向模型,分析了互联网应用的技术进步要素偏向效应的作用机理,并做了实证。研究显示:可将互联网应用作为信息中间品纳入现有模型进行拓展;互联网的普及倾向于强化技术进步的劳动要素偏向,弱化资本要素偏向。基于中国省级面板数据的实证结果,也印证了这个理论推断。这个结论的现实意义是:互联网的普及对于就业和劳动者收入的提升具有促进效应,但对于资本效率的提升促进不明显。这一点也印证了学术界如下发现:近年我国投资效率及资本产出率持续下降。研究的政策寓意是,政府政策应当着力于提升资本产出效率,校正技术进步劳动偏向增强所隐含的负面影响。

The development and popularization of the Internet has not only being changing our lives greatly, but also doing the bias of technological progress at the industrial and enterprise levels. With making use of the existing model on technology progress bias, this paper analyses the mechanism of the factor bias effects of the technology progress of the Internet application, and does an empirical work. The research shows that the Internet application can be integrated into the existing model and do theoretical expansion;the popularity of the Internet tends to strengthen the labor factor bias of technological progress and weaken the capital factor bias. The empirics based on China’s provincial panel data also support this theoretical inference.The practical significance of this conclusion is that the popularity of the Internet has a promoting effect on employment and labors’ income rather than capital efficiency. This conclusion is also consistent with the following findings of the academic research in recent years, the investment efficiency and capital output ratio in China tents to declining. The policy implication of the study is that government should focus on improving the efficiency of capital output in order to correct the negative impact of labor bias in technological progress.
