In this way, a comprehensive analysis of the relationships between climate change and its measures, technology, and economy has been done. The model uses technological change as the accumulation of knowledge capital that is derived from research and development investment. The study investigates the impacts of a climate change measure considering the use of emission permit revenue and technological change induced by the policy implementation in the Japanese economy. Simulation results show that there is compatibility between CO2 emission reduction and positive effects on GDP that depends on the ways of the revenue use and technological change induced by emission reduction. However, it is not possible to find the ways to realize positive effects on both GDP and welfare simultaneously in the study. The sensitivity analysis for the elasticity of substitution between knowledge capital and other inputs also confirms the obtained results.展开更多

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

Since 1978, China has launched a series of R&D programs in promoting environmental science and technology development. Uneven spatial distribution and sectoral structure give us a profile of the present status of ET in China. Both opportunities and constraints are analyzed for the development of ET, and strategies for its future development are presented in this paper.展开更多

New technological findings can enable companies to overcome these challenges. In practice, technology development associated with a long time horizon is often given a lower priority compared with short-term focused product development thus being stronger restricted by everyday business. More and more companies separate their technology development department from product development to promote technological innovations. Due to this additional interface in the R＆D organization new problems arise, resulting in technologies not being implemented in products. The reasons for these problems amongst others concern wrong timing for the transfer or inadequate definition of responsibilities. In this paper of ongoing research, authors introduce a framework to design the transfer processes between technology development and product development. Although there are a number of options for designing the operative transfer, there is no regulatory framework specifying which configuration options are at this particular interface. The approach is to develop a model, which is able to design different company-specific transfer processes taking into account the object being transferred at this interface. Thus, for different objects to be transferred, different transfer processes are designed. The model＇s aim is to enable responsibility of the R＆D management to design their company-specific transfer processes to enable more technologies being implemented into products, thus giving the whole company the possibility to act more innovatively.展开更多

We obtain different investment decision with different amount of firms engaging in the R&D and each firm's expected profit respectively. When the risk (the probability each firm succeed) is not random, it's socially desirable to have more firm engaging in R&D if and only if the relationship among the invest cost, the probability and the prize satisfies some condition, that is, Eπ s(n)≥Eπ s(n-1)I≤α(1-α) n-1 V . When the R&D cost I is certain, more prizes or higher probability will make more firms engage in the R&D and higher prize makes it's socially desirable to have more firm invest in R&D.展开更多
