技术向物质生产力转化的障碍是长期以来经济增长方式难以转变的一个重要原因,但是鲜有相关的经验研究。本文在技术外溢背景下设计了检验技术转化障碍的研究框架,发现了国有企业的研发效率只有非国有企业的一半,但是国有企业和非国有企业都存在技术转化障碍,因此技术转化障碍问题并非国企特殊的难题,而是一个一般性的难题。另外,本文还发现国企研发并不存在所谓的技术外溢,相反非国有企业的研发活动却存在技术外溢。
Obstacles to transforming technology into material productivity have been an important reason for the difficulty in transforming the mode of economic growth for a long time, but there are few relevant empirical studies. In the context of technology spillovers, this paper designs a research framework to test the barriers to technology transformation and finds that the R & D efficiency of state-owned enterprises is only half that of non-state-owned enterprises. However, there are barriers to technology transformation between state-owned enterprises and non-state-owned enterprises. A special puzzle, but a general puzzle. In addition, this article also found that there is no so-called technology spillover in R & D of state-owned enterprises. On the contrary, there is technology spillover in R & D activities of non-state-owned enterprises.
