This article explores the effects of investment upon energy intensity by applying a unique panel data of China's 27 provinces between 2004 and 2013.In addition,it also particularly stuthes other factors,such as energy price,economic structure,and urbanization.The results,based on four econometric regression model results,suggest that in general,the indigenous investment on research and development is a more powerful tool to decrease China's energy intensity regardless of region disparity.The foreign direct investment(FDI) has a prominent but not persistent effect on energy intensity.However,the outward direct investment has not shown its significant impact on energy intensity.At the level of an aggregate economy and China's eastern region,the results demonstrate that FDI improves energy efficiency significantly.For the central and western provinces,FDI does not support the similar conclusion.Based on these analyses,we present the corresponding regional policies for policymakers. 展开更多

When an oligopoly company decides how much should be invested in its R&D, in order to reap the largest profits, it considers not only what its competitors have done but also how its competitors would respond to its action. Therefore, different relationships between oligopoly companies will lead to different responses in their decisions on R&D investment. A correlation deduced from different responses of oligopoly companies in R&D investment with the complete information tactic game theory is presented, and the R&D investment of oilfield service companies was analyzed with this correlation. The correlations of Schlumberger's R&D investment, Halliburton's R&D investment and Baker Hughes' R&D investment were established and analyzed. Meanwhile, two regression models were presented. One was composed of Schlumberger's R&D investment in the previous year and Halliburton's R&D investment. The other was composed of Schlumberger's R&D investment and Baker Hughes' R&D investment in the same year. The accuracy of these two models was proved to be good. 展开更多

Based on the background of China's emerging and transitional market,government subsidies to enterprises are regarded as a " helping hand" of promoting economic structural adjustment. In this paper,using China's A-share agricultural listed companies from 2010 to 2015 as research samples,we discuss the influence of government subsidies on research and development( hereinafter referred to as R & D) investment,and the difference in the relationships between the two from the perspective of different nature of property rights. The results show that,on the whole,the increase in government subsidies does not promote the intensity of R & D investment of agricultural listed companies. And after distinguishing the nature of property rights,the results show that state-owned enterprises can get more government subsidies than private enterprises,and the increase in government subsidies boosts the increase in R & D investment in private enterprises,but there is a negative correlation between government subsidies and R & D investment of state-owned enterprises. This conclusion can broaden the research perspective of the influence factors of corporate R & D investment,and it is of practical significance to further clarify the role of government subsidies in R & D investment decisions of enterprises with different nature of property rights. 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

Using a sample of 126 firms in Chinese IT industry, we developed an empirical model which tests the impact of R&D investment and employee involvement (El) on innovation commercialization. The results showed that the expenditure of R&D has a positive effect on performance of innovation commercialization, while the number of R&D staff has trivial impact on that. The results also revealed that E1 has no direct effect on commercialization performance, but plays a moderating role in the effect of R&D investment on commercialization of innovation. More specifically, the R&D expenditure of a finn with high involvement system has a less positive impact on the number of new products, but a more positive effect on the profit of new products. 展开更多

The results show that there is not a "increasing first, decreasing later" non-linear relationship but a "double negative" relationship between debt level and corporate R & D expenditure.

In recent years, China has promulgated many laws and regulations of environmental protection, gradually forming an environmental regulation system, and most enterprises are under the dual pressure of environmental protection and business performance. It would be a significant way that enterprises undertake R&D activities for a change. This paper is based on the Shanghai and Shenzhen A-share listed heavy pollution enterprises in 2011-2016, which is based on the review and summary of research results of former researchers, combining with current environmental regulation situation of our country, raising the relevant hypothesis between environmental regulations, R&D investment and business performance against heavy pollution industry. Adopting the method of empirical research, it also built the linear regression model which employs the relevant financial data of heavy-polluting enterprises in China as the statistical research sample. The relationship for heavy-polluting enterprises affected by environmental regulations between environmental protection R&D investment and enterprise business performance was tested. The results show that there is a positive influence on the environmental R&D investment and business performance, and a lag effect upon the R&D investment of enterprises to business performance. Finally, the research results were used to evaluates problems existing in the R&D investment on pollution industry in China as well as business performance and we put forward some suggestions on improving environmental regulation standards and technology innovation consciousness as well as optimizing the structure of R&D investment. 展开更多
