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

Environmental technology (ET) refers to the processes and techniques for environmental prevention, reduction, recycling, reuse and rehabilitation. 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

This paper emphasizes the effect of spillovers on R&D (Research and Development) level. When competing firms have spillovers to each other in R&D, cooperation will always increase firms' profits. Only if the positive spillover is large enough, the cooperative R&D level will be larger than the non\|cooperative R&D level. The cooperative level will be smaller than the non\|cooperative level if the positive spillover is small enough. However, the cooperative level is always smaller than the non\|cooperative level while there're negative spillovers to each other. R&D levels are the function of the spillover and will change with the spillover. The changing regularity is related to the sign of spillover and to whether they're cooperative or not. Spillovers made by the competing firms are usually different. When spillovers are small enough, the larger the spillover obtained from the other, the smaller the firm will invest in R&D; inversely, when the spillover is large enough, the larger spillovers obtains from the other, the larger the firm will invest in R&D. 展开更多

To stay globally competitive, manufacturing companies are increasingly under pressure to bring new products and applications to market, improve existing products, and discover new technologies to produce them at a lower price. 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

In a symmetrical static game model, this paper is mainly concerned with the research and development (R&D) strategy of the High Technology (HT) industry and the society's optimal R&D level given the investment revenue. 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

This study analyzes the economic and environmental impacts of a climate change measure in Japan using a single-country dynamic computable general equilibrium model with technological change as an endogenous variable. 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

The implementation of climate technologies and their commercialization ultimately depends on the success of their research and development(R&D) projects. In the Republic of Korea(ROK), twenty-seven climate technologies were selected to boost the greening of existing industries and to develop new green industries to promote a sustainable climate technology development strategy. Rechargeable battery technology, carbon capture and storage(CCS) technology, smart grids, and sewage treatment are all research areas expected to have tangible outcomes in the forthcoming years. As such, they were included in a comprehensive R&D plan for climate technology advancement, which places an emphasis on climate technology development and commercialization strategy. In this study, the R&D plan of the ROK is reviewed by examining its six core climate technology programs: solar cells, fuel cells, bioenergy, rechargeable battery technology, information technology(IT) applications for the power sector, and CCS technology in detail. The climate policy in the ROK aims to find new economic growth engines and to develop new business opportunities while actively participating in international efforts to combat climate change. 展开更多

By introducing a knowledge production function which combines both foreign technology imports and domestic research and development (R&D) expenditure into an endogenous technological progress model, this paper examines the mechanism that determines enterprises' R&D intensity in developing countries, and explores how factors such as technological gap, technology absorptive capacity, innovation environment and innovation ability would impact Chinese enterprises'decision made on R&D intensity. 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

This paper studies the factors affecting the technology-transfer within international research and development (R&D) networks. Specifically, this study examines the characteristics of ties, actors, and international network configuration to assess finn's accessibility to unique technologies. This study was conducted by research analysis in the aerospace industry. The total sample size used in this study is 125 cases of international R&D consortiums from January 1980 to December 2000. The result of this study supports the effects of "strength of tie" and "characteristic of actors" on the technology transfer explained by network theory. It also demonstrates that the international network structure that would facilitate the technology transfer is shaped by dual type of tie; the apparent type of tie is general, usual, and functional tie, and the hidden one is the national culture. 展开更多
