In so doing, we explore different methodologies through which we may analyze the knowledge transmission： both the production function approach and the knowledge function approach. In order to construct the spillover stocks, different dimensions are considered： geographic and technological.展开更多

Technological progress and innovation are essential to helping solve this problem. Research and development （R＆D） stock plays a key role in technological progress and innovation. Through comparisons with some other countries, it is found that China has fallen behind in the R＆D stock for energy technology. The R＆D stock can be improved by two means： one is putting capital and human resources in those strategically key fields; the other is taking advantage of the R＆D resources from abroad. The strategically key fields include energy saving techniques, energy materials, the manufacture of key equipment and new energy resources.展开更多
