Our results suggest that technological gap has no significant single impact on enterprises＇R＆D intensity, but rather influences enterprises＇decision on R＆D jointly with other factors such as degree of openness and human capital. A relative fall in efficiency of technology imitation recently has a negative effect on total R＆D intensity but helps to promote enterprises＇ independent R＆D. In addition, among factors related to R＆D innovation environment, industrial R＆D intensity has a significantly positive impact on enterprises＇ independent R＆D intensity, while regional economies of scale, proportion of large enterprises and proportion of government R＆D investment have some certain negative impacts.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
