技术进步方向理论综述及前景展望

A Review and Prospect on Direction of Technological Change Theory

新古典理论以来,技术进步对经济增长的贡献备受关注,但对技术进步方向的研究在很长时间内并未纳入研究者们的视野。近年来,对技术进步方向的研究获得了方法论意义上的突破性进展。首先回顾技术进步理论的历史轨迹,在此基础上较为细致地梳理了技术进步方向的相关文献,通过介绍其两个主要应用领域:工资不平等问题与环境安全问题,展望了未来一段时间内生技术进步方向理论的可能应用领域,提出可以在横向和纵向两个维度上对此理论作更进一步的拓展。

The contribution of technological change has been an important issue since neoclassical growth theory while direction of technological change has not been incorporated into the researchers＇ perspective. In recent years, research on direction of technological change has gained mathematical breakthrough. Based on the review of the historical routine of technological change theory,the article carefully teased a series of literatures of direction of technological change, introduced its two main application fields： wage inequality and environment safety, prospected possible application fields in two dimensions.
