This paper constructs China national and provincial physical capital and human capital for the period 1984–2006. The estimation of physical capital is extended to the use of sources of fund and ownership of fund. The growth accounting framework is used to calculate the output, input and total factor productivity growth rates. The relative variance method is used to compare the relative importance to output growth by input growth and productivity growth. The empirical findings show that although output growth in post-reform China has been contributed much by growth in total factor productivity, output volatility has relied more on input growth, and TFP growth has not been supported by complementary changes. There are regional differences when looking at the performance of individual growth rates.  相似文献

This paper examines the empirical evidence on the impact of performed R&D and of R&D embodied in intermediate and capital goods on productivity performance in 10 major OECD countries over the last two decades. To quantify intersectoral and international technology flows, industry-level embodied R&D variables were constructed from an input–output (IO) R&D embodiment model. The productivity variables used are discrete Divisia growth indexes of total factor productivity (TFP), which were estimated from an IO growth accounting model. The results from pooled regressions indicate that the rates of return of the R&D variables were positively significant and increasing in the 1980s. In particular, embodied R&D is an important source for TFP growth in services, indicating very high social returns of the flows of capital-embodied technology into this sector. Moreover, the information and communi-cation technology (ICT) cluster of industries played a major role in the generation and cquisition of new technologies at the international level.  相似文献

Technology ‘spillovers’ are increasingly being recognized as sources of productivity growth. International ‘convergence’ in productivity levels has also been noted in recent studies. This paper reports a study of international total factor productivity (TFP) growth for 11 industrial sectors in seven OECD countries. Spillover variables are defined based on interindusty and international invention input–output (I(IO)) weights. These variables are tested against import-weighted variables. The study concludes that I(IO)-weighted R&D ‘spill-ins’ are important determinants of TFP growth and that convergence is dependent on domestic RBD.  相似文献

ABSTRACT

This paper looks at the relation between the R&D knowledge base of city-agglomerations and knowledge sourcing in product innovative small and medium-sized enterprises (SMEs). The small open Belgian economy is used as a test case. The characteristics of the city-agglomeration’s R&D knowledge are posited to be instrumental for SMEs’ reliance on particular sources of information for innovation. The R&D knowledge base is studied as a multidimensional concept consisting of R&D capacity, R&D specialization and R&D diversification. A representative sample of product innovative SMEs drawn from two waves of the Community Innovation Survey between 2008 and 2012 reveals that a strong R&D capacity at city-agglomeration level favours private external information sources for innovation, but has no influence on the likelihood to rely on public sources for innovation. Accordance between specialization of the private R&D knowledge base and the SME’s activities positively influences the use of clients as information sources for innovation, whereas under these circumstances supplier responsiveness turns out to be less frequently solicited for. A more diversified private R&D environment reduces the reliance on universities and public research organizations as information sources for innovation. A public R&D knowledge base specialized in natural sciences or engineering favours information sources from universities.  相似文献

This paper presents several new methods for measuring intersectoral knowledge spillovers, and applies these methods in an analysis of productivity growth in manufacturing for a cross-country, cross-sectional sample for the 1980s. It is argued that existing methods of measuring such intersectoral knowledge spillovers are mostly aimed at measuring so-called crent spillovers'. The methods developed here are aimed at measuring knowledge spillovers—an additional aspect of the spillover process. The empirical analysis shows that there are indeed differences between these two types of spillover measure.  相似文献

R&D and productivity: A broad cross-section cross-country look   总被引:2,自引:0,他引:2  
The empirical literature on R&D and productivity has shown that there is indeed a positive influence of R&D investment on output growth. However, the exact relation depends to a large extent on the approach chosen (i.e., functional form). Because most studies concentrate on a limited number of countries or sectors and use their own specific methodology, comparison is difficult. This paper aims at providing a broad overview of cross-country and cross-sector differences in the relation between (direct) R&D and output growth, using a common methodology, so that comparison is easier. The functional form used is a translog production function, which is applied to data for 15 manufacturing sectors and 9 principal OECD countries.  相似文献

Using US input–output data for the period 1958–87, I find strong evidence that industry total factor productivity (TFP) growth is significantly related to the TFP performance of the supplying sectors, with an elasticity of almost 60%. R&D intensity is also found to be a significant determinant of industry TFP growth, with an estimated return of about 10–13% and the return to embodied R&D is estimated at 43%. Direct productivity spillovers, from the technological progress made by supplying sectors, appear to be more important than spillovers from the R&D performed by suppliers. They also play a key role in explaining changes in manufacturing TFP growth over time. Changes in the contribution made by direct productivity spillovers to TFP growth account for almost half of the slowdown in TFP growth in manufacturing from 1958–67 to 1967–77, and for 20% of the TFP growth recovery in this sector from 1967–77 to 1977–87. Changes in R&D intensity and embodied R&D are relatively unimportant in explaining movements in manufacturing TFP growth over these three periods.  相似文献

The paper examines the importance of interindustry technology flows in finnish manufacturing in the 1980s and early 1990s. An attempt is made to distinguish between embodied technology flows and spillovers, so clarifying the spillover concept.Embodied technology covers intermediate goods and capital equipment. The embodied technology data that have been used are partly based on input—output analysis, while the spillover estimates presented are based on measures of technological distance based on the industry-specific distributions of R&D expenditures. Econometric analysis of the effects of the various technology inputs on total factor productivity implies that technology embodied in foreign machinery, domestic spillovers and, to some extent, the firms' own R&D have been the most important technology sources on average.  相似文献

This paper examines the role of external service linkages in the innovation and market peformance of small manufacturing firms (SMFs). Survey data from a technological cross-section of 146 Western New York SMFs are summarized. The data suggest a helpful role for consultants in the product development efforts of innovative firms, especially those that serve foreign export markets. Several multiple discriminant models are presented, each of which suggests an interactive connection between SMF commercial performance, externa) technical links, innovation propensity and in-house R&D. It is argued that innovative SMFs that exploit specialized technical services perform significantly better than comparably sized firms that rely solely on in-house resources. It is also argued that the quality of a region's producer service environment may have a significant bearing on the growth potential of its SMF population. The paper concludes by discussing the main academic and public policy implications that flow from the empirical results.  相似文献

Public procurement is increasingly viewed as having important potential to drive innovation. Despite this interest, numerous barriers prevent the public sector from acting as an intelligent and informed customer. This paper seeks to understand how barriers related to processes, competences, procedures and relationships in public procurement influence suppliers? ability to innovate and to reap the benefits of innovation. We address this by exploiting a dedicated survey of public sector suppliers in the UK, using a probit model to investigate the influence of structural, market and innovation determinants on suppliers? perception of these barriers.  相似文献

This paper shows that R&D subsidy policies at the European Union (EU) and national levels stimulated labor productivity in Central and Eastern European countries (CEEC) in the years after their entry to the EU. However, the average impact of national funding on labor productivity was higher for countries in the Western control group than in the CEEC sample. EU R&D subsidies compensated the CEEC in part for the greater innovation impact of Western economies. Although they crowded out some R&D subsidies by local governments at the country level, the EU subsidies crowded in many national and local subsidies at the firm level. Local/regional state innovation aid to enterprises encouraged no increase in labor productivity in all but one of the sample CEEC countries. These impacts are assessed in a sequential structural econometric model estimated using Eurostat’s collection of Community Innovation Surveys covering the years 2006–2014.  相似文献

In this paper, we measure the effect of internal R&D and various spillover concepts on productivity growth, using a database for France that covers the period 1978–92. Three spillover concepts are distinguished: rent spillovers related to investment goods; rent spillovers related to intermediate goods; pure knowledge spillovers. When production is measured by gross output, all three spillover concepts yield positive and statistically significant coefficients. Each concept has a measurable effect on technological progress at the sectoral level.  相似文献

This paper estimates the contributions of R&D spillovers to four high-tech industries in Japan—general machinery, electrical machinery, transportation machinery and chemicals—by estimating the trans-log cost and share functions that include the R&D stock variables of own and spillover-source industries. The candidates for spillover- source industries are selected on the basis of large R&D flow or R&D proximity. The R&D flow measures the spillover embodied in purchased intermediate goods using input–output coefficients. The R&D proximity measures the extent of similarity between a pair of industries of the distribution of R&D expenditures across research fields, and is expected to show the likelihood of spillover at the R&D stage. The results suggest that electrical machinery benefited from R&D in the chemical industry, through the purchase of intermediate goods, whereas general machinery and transportation machinery benefited from R&D in the metal products industry, through R&D proximity. There was no evidence of the chemical industry benefiting from R&D spillovers. These results clearly imply that the contributions and the channels of R&D spillovers are diverse, casting doubt on earlier studies that used weighted sums of R&D expenditures (or their stocks) of other industries as aggregate spillover variables.  相似文献

Economists have managed to find a positive impact of R&D efforts on productivity. However, the empirical results of their studies have not explained the observed sectoral differences in this important impact. With due reference to three global industries, namely, chemical, computer, and electrical/electronic, the objective of this study is to evaluate the impact of technological opportunity on the productivity of R&D activities. Technological opportunity refers to the ease of achievement of innovations and technical improvements, which could be jointly represented by the intensities of knowledge spillovers, inter-firm research overlap and scope of research. In this study, the degree of technological opportunity is quantified by patent statistics. The empirical findings confirm a positive relationship between technological opportunity and the productivity of R&D effort, and the estimated rate of return falls within the range as reported by past studies.  相似文献

This paper investigates whether the Yale Technology Concordance (YTC) succeeds in identzbing technology flows between sectors. As a test, total factor productivity (TFP)-R&D regressions based on the YTC matrix are compared with regressions using technology flow data constructed fram input–output matrices and randomly created interindusty linkages. Because results based on the YTC do not dzffer markedly from the other estimates, one cannot easily infer @om the empirical evidence whether the YTC matrix appropriately captures interindusty technology flows or not.  相似文献

In this article, a Tullock contest success function is used to model an innovation contest with endogenous innovation height. We can prove stability for this endogenous prize contest. The winner of the contest gains a monopoly rent, which has two dimensions. In the first dimension the winning firm influences the innovation height. The second dimension is the life span of the temporary monopoly. This life span is determined by the contest designer, who can be asocial planner or the consumers. We find interior solutions in both cases, whereas consumers prefer a monopoly life span below the social optimum. Furthermore, the optimal number of firms in the contest is two.  相似文献

The papers in this issue are directed towards the development of invention input–output (I(IO)) coefficients. They discuss the procedures for creating I(IO) coefficients using the Yale Technology Concordance, which assigns patented inventions to the industry of manufacture and sector of use, utilizing the International Patent Class system. Tests of reliability of the I(Io) coefficients and their use in economic studies are reported.  相似文献

The aim of this paper is twofold. First, we estimate production functions for the Mexican manufacturing sector and for 14 comprehensive groups, allowing us to construct various measures of multifactor productivity. Second, we analyse some of the determinants of productivity growth. We find that, on the one hand, there is a positive relationship between market concentration and technology adoption; on the other hand, both technology adoption and human capital promote productivity, whilst market concentration exerts a negative influence on it. Our results suggest that, once controlling for the effect on technology adoption, more concentration impacts negatively productivity growth.  相似文献

Using data from the decennial US Censuses of 1950, 1960, 1970, 1980, 1990, and 2000, I construct matrices of employment by 267 occupations and 64 industries and then aggregate the occupations into four categories: (i) knowledge producers; (ii) data processors; (iii) service workers; and (iv) goods-processing workers. I find that information workers (the sum of the first two categories) increased from 37% of the workforce in 1950 to 59% in 2000. Then, using an input–output decomposition analysis, I find that the growth in information workers was driven not by a shift in tastes toward information-intensive goods and services (as measured by the composition of final demand) but rather by a roughly equal combination of the substitution of information workers for goods and service workers within the structure of production of industries and the unbalanced growth effect (from differential rates of industry productivity growth). Finally, on the basis of regression analysis, I find that R&D expenditures and computer investment are positively associated with the growth in knowledge workers but negatively associated with the growth of data workers.  相似文献

This paper assesses the relative eco-efficiency changes in the electricity and gas sector (E&G)' production and consumption chains in 28 European countries. We propose a novel robustness assessment for the productivity index, specifically adjusted to value-based data envelopment analysis. Overall, results indicate that total factor productivity gains have been mainly driven by the catch-up effect across all chains of the E&G sector. When a more demanding perspective concerning negative environmental externalities is adopted, we find that the number of European countries that achieved productivity gains across all chains decreases. Besides, results depict the existence of lower productivity gains for the direct production chain when compared with the direct and indirect supply chains of the E&G sector. Germany, Luxembourg, and Belgium were consistently viewed as innovators across all chains, according to the environmental perspective. Several Eastern Europe countries usually viewed as policy laggards that resisted adopting the ambitious European decarbonization targets, showed total factor productivity gains in the supply chain of the E&G sector under a more environmental demanding perspective. Czechia was the only country with productivity losses across all chains, due to increasing coal-fired electricity generation in the time horizon assessed. The current partial return to coal as a source of electricity, due to the geopolitical tensions between Russia and Europe, brings additional challenges to the enhancement of the eco-efficiency of the European E&G sector.  相似文献
