本文采用永续盘存法,系统地估计了中国31个省级行政单位1990—2014年各年末的R&D资本存量。在估计过程中,对部分R&D内部支出和科技人员劳务费部分缺失数据进行了处理,并对基期R&D资本存量、折旧率和R&D投入价格指数的选择进行了研究。本文与现有文献估计的R&D资本存量增长趋势基本一致,但略微低于现有文献的估计结果。笔者发现,中国R&D资本存量在1990—2014年间经历了快速增长,年均增长率为13.66%。但R&D资本存量的省际差异较大,东部地区的R&D资本存量占GDP比重显著高于中西部地区,而且还有进一步拉大的趋势。因此,中西部地区转变经济发展方式的重要路径之一在于加大R&D投入力度。 相似文献

永续盘存法是测度资本存量的常用方法,但其在军事资本中的应用还处于起步阶段。本文利用永续盘存法对我国的军事资本进行了测度。结果表明,我国军事资本总体上呈现上升趋势,但军事资本的增长速度要落后于总资本的增长速度。因此,要在考虑经济承受力的情况下,逐步增加我国的军事资本,保证我国良好的经济发展环境和国家主权不受侵犯。 相似文献

This paper examines the impact of foreign management as a separate input in a competitive economy open to both international trade and international movement of productive capital. Three inputs (capital, labor, management) are used to produce two final goods in a model characterized by competition, homogeneous products, and full employment. This model provides a simple starting point for the study of multinational firm activity, building on the fundamental competitive factor proportions model of production and trade. A clear distinction arises between international movements of capital and management, and international movements of the two inputs are linked. [F 11, F 23] 相似文献

We revisit the widely discussed contribution of investment in ICT to economic growth, focusing on differences in productivity and quality of ICT across countries and time. In a growth accounting approach, we look at the way rates of return and rates of asset price decline measure these aspects. Conducting a sensitivity analysis with data from the EU KLEMS database for the years 1990–2007, we introduce a constant rate of return and a constant rate of ICT price decline. Both alternative measurements somewhat downplay the role investment played relative to growth in multifactor productivity in the U.K. and the U.S. during 1995–2000. Moreover, we show that more than half of the ICT contribution to labor productivity growth results from changes in capital quality and composition rather than from quantity. 相似文献

The relative roles of factor inputs and productivity are estimated in explaining the level of economic development. For a large sample of countries, it is shown that international differences in factor inputs account for between two thirds and three quarters of international differences in output per worker if alternative identifying productivity assumptions and a quality-adjusted measure of human capital are employed. For a sample of OECD countries, it is found that all differences in output per worker can be attributed to differences in factor inputs, leaving no role for international productivity differences. This result supports the reasoning of a traditional neoclassical growth model. 相似文献

We use the normalized quadratic cost function, introduced by Diewert and Wales (1987), to measure and analyze the rate and biases of technical change at the sectoral level in eleven major U.S. industries — manufacturing, construction, mining, agriculture, finance, health, wholesale, transportation, education, hospitality, and utilities — using annual KLEM (capital, labor, energy, and intermediate materials) data from the World KLEMS database, over the period from 1947 to 2010. We extend the work in Feng and Serletis (2008), by taking a new approach to econometric modeling, merging the econometric approach to productivity measurement with recent state-of-the-art advances in financial econometrics. In particular, we relax the homoskedasticity assumption and instead assume that the covariance matrix of the errors of the flexible interrelated factor demand systems is time-varying. We also pay explicit attention to theoretical regularity, treating the curvature property as a maintained hypothesis, thus achieving superior modeling in the context of a parametric nonlinear factor demand system that captures certain important features of the data. 相似文献

根据城乡生产函数差异的特征事实构建了城乡收入差距模型,利用我国各省1997—2009年数据研究城乡劳动力比、固定资产比、人力资本比、农业中间品投入、工业化和第三产业规模对城乡收入差距的影响。结果显示,我国城乡要素生产率与城乡要素配置的差异对城乡收入差距具有决定性作用;城乡劳动力比的增长明显有助于缩小城乡收入差距,而城乡人力资本比、固定资本投入比、农业成本、以及相邻地区间的相关性都导致了城乡收入差距的扩大。缩小城乡差距的重要途径是加快农村劳动力的城市化、增加农村教育投入、提高农业生产率、增加农村的物质资本投入,各省缩小城乡收入差距的努力对邻近省份也会产生积极影响。 相似文献

This paper links data on continuous training from the EU Labour Force Survey (LFS) to information on skill levels and earnings from the EU KLEMS growth and productivity accounts, to examine the relative magnitudes of continuous workforce training versus human capital formation through the general education system in the European Union. The measurement methodology draws from the literature on measuring intangible investments by firms and sources of growth in an accounting framework. The results suggest that in the EU15 group of countries, intangible investments in continuous training represent just under 2 percent of GDP or about 35 percent of expenditure on general education. The share of GDP accounted for by training is less than a third as large in the new member states. A growth accounting method is employed to show that failure to account for continuous training leads to an underestimate of the impact of human capital on output growth in the EU. 相似文献

本文报告了根据 Jorgenson 方法所做的中国与美国的制造业分行业的全要素生产率的国际比较,以及中国制造业1985—1994年间全要素生产率的增长率。比较发现,就资本生产率和全要素生产率来说,中美之间的差距相对比较小,而就劳动生产率的差距来说,中美之间的差距相当大。美国制造业劳动生产率大约是中国制造业劳动生产率的17.67倍,但是美国制造业的全要素生产率大约是中国制造业全要素生产率的5倍。而中国制造业全要素生产率在1986—1994年间的平均增长实际有0.67%的减退。 相似文献

In the twenty-first century, the Spanish textile and apparel industries have faced substantial challenges, resulting in declining sales and employment. This study concentrates on the apparel industry, since its economic challenges and opportunities differ from those of the textile industry. The analysis employs a transcendental logarithmic cost function to investigate the presence of scale economies and the interrelationships among inputs of domestic capital, labour and intermediate goods as well as outsourced intermediate products for the Spanish apparel industry and discusses the implications for its future competitiveness and the demand for domestic inputs. The results are consistent with diseconomies of scale or, in the case of one model, possibly constant returns to scale, indicating that some contraction of the industry due to international competition will not raise unit costs. All of the inputs except for capital and intermediate goods were found to be substitutes. An important finding is that the cross elasticity values of both labour and domestic intermediate goods with respect to the price of outsourced goods have risen over time, indicating an increased sensitivity of the quantity demanded of these home-country inputs to the price of imported intermediate goods. It follows that domestic input markets will be more substantially affected by international prices for outsourced inputs as the industry tries to maintain its competitiveness in the global environment. 相似文献

France faces substantial challenges as the economic integration of Europe and the international economy continues. This article uses a dynamic aggregate translog cost function with inputs of capital, labor, and imports to examine the likely impact of closer world economic ties on France. This technique allows one to estimate short- as well as long-run direct price elasticities of demand for the inputs and cross-price elasticities for each respective input pair. The findings of the article include that (1) the French economy is becoming more sensitive to changes in import prices and (2) all the inputs are substitutes for one another. These results suggest that continuing international economic integration will present substantial challenges to the French economy. The short-run estimates of direct and cross-price elasticities are consistent with the Le Châtelier principle, except for the cross-price elasticities between capital and labor. Some possible reasons for the latter result are discussed in the article. (JEL F14, O10, O12) 相似文献

The Spanish textile and apparel manufacturing sectors have been badly impacted by the global recession as well as the removal of quotas that were in place with the Agreement on Textiles and Clothing (ATC). This study employs a cost function to investigate the presence of scale economies and the interrelationships among inputs of domestic capital, labor, and intermediate goods as well as outsourced (imported) intermediate products for the Spanish textile industry in a global environment that has become increasingly competitive. While there is evidence of scale economies at low output levels, there is also some evidence consistent with diseconomies of scale at the highest output levels. All of the inputs appear to be substitutes for one another except for domestic capital and outsourced intermediate goods. An important finding is that the demands for both labor and domestic intermediate goods have become increasingly sensitive to the prices of outsourced inputs. The estimated coefficients of dummy variables indicate that reduced international trade restrictions have put downward pressure on unit cost for the industry in recent years. These results suggest that the Spanish textile industry and its domestic suppliers will be increasingly challenged by international competitive pressures. 相似文献
