英文文献：Intangible capital and sectoral energy intensity: Evidence from 40 economies
英文文献作者：Shenglang Yang
英文文献摘要：
Intangible capital has been found to be an increasingly important source of productivity and economic growth. However, its effects on energy intensity have received little attention. Given the importance of reducing energy intensity, this study tests the relationship between sectoral intangible capital and sectoral energy intensity in 40 economies from 1995 to 2007 using data from World Input Output Database (WIOD). It is found that the increase in sectoral intangible capital is associated with the decline in sectoral energy intensity. The results remain robust given various forms of econometric specification (OLS, random effects, fixed effects and system GMM). Compared with previous literature, this study proposes a simple theoretical linkage between sectoral intangible capital and sectoral energy intensity, and for the first time confirms this relationship worldwide. This study also provides policies implications in promoting intangible investment and the knowledge economy.
