中国R&D资本存量测算:1952~2014年   总被引:1,自引:0,他引:1  
2008年SNA修订了R&D支出的核算方法,R&D支出不再视为中间消耗,而是作为固定资本形成处理。本文依据2008年SNA和我国R&D统计调查数据等,科学测算了1952年以来每年R&D活动所形成的资产价值,同时对R&D资产进口和出口进行了适当调整。然后,在合理选取和估计R&D资产折旧率、R&D价格指数和基年R&D资本存量的基础上,根据永续盘存法对我国1952~2014年R&D资本存量进行了测算。结果显示,我国R&D投资与R&D内部经费支出的年平均比例为95.5%,我国R&D资本存量总体上呈快速增长趋势,2014年达到42244亿元,且R&D资本存量与GDP之比呈“N”形趋势,经历了先上升后下降再上升的过程。  相似文献

多视角下R&D资本化测算方法比较与应用   总被引:1,自引:0,他引:1  
R&D资本化基本测度方法主要有三种:Goldsmith方法、Griliches方法和BEA方法,在不同的经济理念下,三种测度方法既各有特色,又有共同特征。在Goldsmith方法设定理念中,当期R&D资本存量由当期不变价R&D投资额与扣除折旧后的上一期R&D资本存量两部分构成,且当期不变价R&D投资额全部转化为当期资本存量;在Griliches方法设定理念中,当期R&D资本存量由上一期不变价R&D投资额与扣除折旧后的上一期R&D资本存量两部分构成,且上一期不变价R&D投资额全部转化为当期资本存量;而在BEA方法设定理念中,当期R&D资本存量由当期不变价R&D投资额与扣除折旧后的上一期R&D资本存量两部分构成,且当期不变价R&D投资额的一半发生折旧。在具体测算过程中,三种测度方法均要考虑R&D资本存量增长率、R&D资本折旧率、R&D支出价格指数等关键参数的设定。同时,基于三种测度方法比较研究,将其应用于中国R&D资本化估算实践。  相似文献

The Chinese high-tech industry has developed greatly since the beginning of China's “National High-tech R&D (863) Program” and “China Torch Program”. This paper introduces a conceptual model extended from the innovation value chain model to simultaneously estimate the R&D and commercialization efficiencies for the high-tech industries of 29 provincial-level regions in China. To match reality, a network DEA incorporating both shared inputs and additional intermediate inputs is constructed to open the “black box” view of decision making units used in single-stage DEA. This study is the first attempt to link the R&D and commercialization with a solid theoretical foundation and feasible mathematical methods. The empirical findings show that most of the 29 regions have low efficiency in the commercialization sub-process compared to the R&D sub-process, although there are regional differences in China's high-tech industry. Pearson correlation shows that the R&D sub-process is not closely correlated to the commercialization sub-process in terms of efficiency. Our analysis can provide information for the formulation of policies to achieve high innovation efficiency.  相似文献

This paper estimates the effects of interindustry R&D spillovers on the cost and production structure for 10 Canadian manufacturing industries. Because of their high-tech nature and productivity performance, spillovers from electrical and electronic products are distinguished from other spillover sources. Generally, spillovers from electrical and electronic products generate cost reductions and render production processes for Canadian manufacturing industries more capital intensive (i.e. either more physical or R&D capital intensive). Social rates of return for R&D capital are calculated for all 10 industries. The social rates are 5–11 times greater than are the private rates. Indeed, the social rates are high for all the industries. This implies that the electrical and electronic products industry is an important interindustry spillover source but, like other industries, a major spillover-using industry.  相似文献

This paper employs a Russell multi-activity network DEA model and divides the overall innovation process into the upstream Research and Development (R&D) process and the downstream commercialization process to appraise the innovation performance of China's high-tech industries from 2009 to 2013. This model can deal with the problems of intermediates, shared inputs and slack-based measure in a unified framework, and the result can provide policy makers with process-specific information on how to improve the innovation performance of China's high-tech industries. The main findings are presented as follows. First, the overall efficiency of China's high-tech industries still remains at a low level, which has its roots mainly in commercialization inefficiencies other than R&D inefficiencies. Second, for most provinces, their R&D efficiencies do not match up with their commercialization efficiencies. Finally, the innovative activities of China's high-tech industries should be driven by the market demand -oriented for the improvement of innovation efficiency.  相似文献

We investigate whether measures of intangible capital based on advertising and R&D can explain variation in Tobin's Q ratio for the pharmaceutical and chemical industry. The study is motivated by prior literature studying this relation in other industries, recent literature investigating intangible capital in this industry, and the larger controversy about whether stock valuations have been high due to irrational investors or large investment in intangible capital. We find that our measures of intangible capital are statistically significant determinants of Q and explain 20% of the variation in our sample. When age and industry are incorporated into the model our explanatory power reaches 25%.  相似文献

Although significant progress has been made in China's basic research in recent years, there remains a wide gap between research in China and that from developed countries. How to optimize the allocative efficiency of research resources is of great importance for increasing research output. In this paper, using the fixed effect stochastic frontier model based on the translog production function, we estimate output and substitution elasticities of research and development (R&D) inputs at universities in China's provincial level during 2009–2016. We find that the R&D technical efficiency of China's universities, after a rapid growth, has tended to become relatively stable. Improvements of internationalization degree and exogenous R&D capabilities are conducive to promoting R&D technical efficiency, whereas expenditures from government grants inhibit the promotion of R&D technical efficiency; the effects of R&D capital deepening and internet penetration are not evident. The output elasticity of R&D capital is much higher than that of R&D personnel, suggesting that R&D capital is the main driving force of research output. The substitution elasticity between R&D capital and personnel has experienced a change from substitution to complementary since 2014. To realize sustained growth of research output, we should increase R&D input with positive output elasticity or reduce R&D input with negative output elasticity, making the necessary trade-offs according to the substitution relationship between the two R&D inputs.  相似文献

China is concerned to improve the technical capability of its industry. It has chosen Science and Technology Industry Parks (STIPs) as the model for incubating its R&D capability and driving its hi-tech policy. Against this background, the authors examine two main issues. First, we review assessments of university science parks in the UK and a wider context extracted from the literature before examining specifically China's R&D intensity and hi-tech policy. Second, we examine the performance of hi-tech companies situated on STIPs and those located outside STIPs, comparing their success in commercializing technology. We pay particular attention to the role of entrepreneurship in this activity by those engaged in it. Our findings are based on secondary quantitative data and qualitative data collected by means of interviews and focus groups in the Beijing and Shanghai areas in March 2004. From our research it is clear that China lags behind OECD countries in its R&D capability and the technology transfer rate is low, hampering China's hi-tech potential, although China is achieving some success in hi-tech exports, notably of ICT goods. Furthermore, innovation capability, locational factors such as being located in a regional industry cluster (in or outside STIPs), guanxi and networking opportunities, entrepreneurial skills, including international business experience and access to more financial sources and capital for developing the business, are essential for commercializing technology effectively in China. The role of entrepreneurship is evident. However, it remains still underdeveloped in China's STIPs.  相似文献

The paper presents new econometric evidence on the relationship between total factor productivity growth and the R&D expenditures of Canadian manufacturing industries in the presence of interindustry and international spillovers of technology. In contrast to studies that presume that international spillovers are incorporated in imports of intermediate and/or capital equipment goods, the present paper assumes that the principal channel of transmission of new technology is foreign direct investment. Three original proxies for international spillovers use information on patenting, the size and the origin of foreign ownership in the host country and the R&D expenditures in the country of origin. The results suggest that the nexus between industry's own R&D expenditures and the TFP growth is significant and positive, especially for the process-related R&D. Domestic interindustry spillovers of new technology have a larger effect on TFP than industry's own R&D expenditures. All three proxies for international technology spillovers are associated positively and significantly with TFP growth. However, international spillovers contribute to TFP growth less than domestic interindustry spillovers and less than own process-related R&D.  相似文献
