To analyze how capital mobility affects economic growth and convergence, this paper will use the analytical solution to the neoclassical growth model with a constant saving rate, beginning with the closed-economy Solow growth model. An introduction to international capital flows will follow. In an open economy, free capital mobility assures an instantaneous convergence in interest rates that, under a perfect competence situation, implies the instantaneous convergence in income levels among homogeneous countries. Taking into account this question and to reconcile these results with empirical evidence, that is, with the gradual convergence observed, the assumption is introduced that in spite of free capital mobility, there are international credit restrictions. In this case, we will show how the rate of convergence depends on the international capital inflows received. The authors would like to thank Maria Isabel Abradelo for her help in translating this paper.  相似文献

As a needed methodological complement to the existing large-scale complex policy modelling for energy technology diffusion, this paper contributes to an analytical exposition of the fundamental mechanism of international technology diffusion (ITD) for energy technological progress. We offer two different and complementary perspectives to explore the dynamics of energy technology diffusion and progress. We first develop a Solow-type efficiency-improving model of energy technological progress which is described by improvements in primary energy-augmenting efficiency. We further provide a Romer-type variety-expanding model of energy technological progress which is represented by the expansion of differentiated varieties of primary energy technology blueprints. Analysis based on two different models reaches consistent results: there are potential forces in the world economy – working through ITD – that pull individual countries to advance energy technology, ensuring a cross-country convergence in the growth rates of energy technology in the balanced growth path. While ITD plays a role in a cross-country convergence in technological growth rates, cross-country differences in the efficiency of undertaking indigenous research and the capacity of absorbing foreign technology spillovers would lead to a cross-country divergence in the absolute levels of energy technology.  相似文献

Long run convergence implies that the convergence hypothesis will be rejected if the income differential is not stationary. However, this definition is valid only if the catching-up process between the two countries is already over. If we take into account catching-up dynamics, then poorest countries should obtain a faster growth than developed countries. Thus, income gaps should integrate decreasing time trends. We formalise this hypothesis theoretically using a stochastic neoclassical growth model with heterogeneous technology. We then apply this model to the issue of per-capita GDP catching-up of eight MENA countries towards the level of income in Europe. We approximate the nonlinear deterministic trend by a linear function with breaks and apply panel unit root tests with breaks. The analysis reveals firstly that the periods of divergence outnumber the periods of convergence. Secondly, since the year 2000 all countries but Syria have been converging toward the European per-capita income level.  相似文献

This paper presents an extended model of cumulative growth inwhich the effects of innovation and catching-up are considered.Innovation adds another source of cumulative growth to thatof traditional models and allows a consideration of the importanceof non-price determinants of international competitiveness.Catching-up is the major force leading to convergence in productivityowing to the effect of the diffusion of technology. The modelallows one to analyse whether cumulative forces may lead tostable growth and whether this solution generates convergencein productivity levels. The structural model is tested for aset of OECD countries over the period 1965–94.  相似文献

Abstract.   The convergence hypothesis for tourism markets is based on the tenet that when tourism markets are converging the difference between total international visitor arrivals to a country and international visitor arrivals from a particular country will be stationary. We argue that if this is true, then convergence can also be tested through examining whether total visitor arrivals and visitor arrivals from a particular market are cointegrated. We test the convergence hypothesis by examining visitor arrivals to Fiji from eight tourist source markets, using both unit root and cointegration tests. We find strong statistical evidence that Fiji's tourism markets converge.  相似文献

全球大部分技术来源于少数发达国家,在经济全球化背景下,技术通过各种渠道在世界范围内的扩散,对各国的技术水平和经济发展产生了重要影响,国际技术扩散日益成为经济增长理论关注的核心问题之一。本文从三个方面对国际技术扩散的文献进行了梳理和总结,包括技术扩散度量的方式、技术扩散的途径及影响技术扩散的因素。相关研究文献表明,在数量上更精准地度量国际技术扩散已经取得了重要进展;通过国际贸易实现的技术扩散能够提高几乎所有国家的生产效率,但是与FD I流入相联系的技术扩散溢出效应却在发达国家和发展中国家之间呈现出显著的差异;一国的地理距离、技术差距、要素禀赋以及政治制度等若干因素为理解这一现象提供了解释。  相似文献

The increasing diversity of average growth rates and income levels across countries has generated a large literature on testing the income convergence hypothesis. Most countries in South-East Asia, particularly the five founding ASEAN member countries (ASEAN-5), have experienced substantial economic growth, with the pace of growth having varied substantially across countries. Recent empirical studies have found evidence of several convergence clubs, in which per capita incomes have converged for selected groupings of countries and regions. This paper applies different time series tests of convergence to determine if there is a convergence club for ASEAN-5, as well as ASEAN-5 and the USA. The catching up hypothesis states that the lagging country, with low initial income and productivity levels, will tend to grow more rapidly by copying the technology of the leader country, without having to bear the associated costs of research and development. Given the important effects of technological change on growth, this paper also examines whether ASEAN-5 is catching up technologically with the USA.  相似文献

对外贸易、金融改革和经济增长:来自中国的证据   总被引:1,自引:0,他引:1       下载免费PDF全文
本文根据技术扩散模型阐释,中国的技术进步取决于它对先进技术的吸收能力和可吸收的世界先进技术集合的乘积。金融改革通过消除经济扭曲提升我国的吸收能力。如果国际先进技术通过对外贸易扩散到中国,那么对外贸易和金融改革在增长中就存在相互促进的作用。利用中国改革开放后的数据,我们没有发现对外贸易(出口或进出口)和金融改革在促进经济增长中有显著的互补作用。该结论在控制条件收敛、其他经济增长因素、分省和时间效应后成立,并在解决贸易的内生性后仍然稳健。将该结论和我们已发现的金融改革和外商直接投资在促进经济增长中有显著的互补作用的结果相对照,可见,与国际贸易相比,国际先进技术更可能通过外商直接投资扩散到中国。  相似文献

This study proposes a quantitative method for investigating the structure of international technology diffusion. By using network analysis, this study defines the structural configuration of each country within the international diffusion network by measuring its degree, closeness, and betweenness centralities. In addition, this study distinguishes between embodied technology diffusion, measured by multilateral trade, and disembodied technology diffusion, measured by patent citations, in individual countries. This study empirically tests a sample data set of international technology diffusion taken from 48 countries. The empirical results show that the structural configuration of countries exhibits similar patterns in both embodied and disembodied diffusion networks. Significant global stratification patterns exist in the capability of national international technology exportation and brokerage advantages. Moreover, this study distinguishes four blocks of countries that play different roles in international technology diffusion: the leading countries provide a source of technological knowledge; an intermediate group diffuses the knowledge acquired from the source; a third group is in the process of initiating the export of technological knowledge; and a final group of countries absorbs technological knowledge without reciprocal exportation. Finally, this study identifies two types of catch-up strategies that newly industrialized or developing countries can use to move up the international technology stratification.  相似文献

Research Frontiers in the Economics of Climate Change   总被引:1,自引:1,他引:0  
Academic and policy debates over climate change risks and policies have stimulated economic research in a variety of fields. In this article I briefly discuss eight overlapping areas of current research in which further effort is particularly warranted. These areas include decision criteria for policy; risk assessment and adaptation; uncertainty and learning; abatement cost and the innovation and diffusion of technology; and the credibility of policies and international agreements. Further analysis in these areas not only will advance academic understanding but also will provide insights of considerable importance to policymakers.  相似文献

Technology transfer plays a key role in global efforts to reduce greenhouse gas emissions. In this paper, we characterize the factors that promote or hinder the international diffusion of climate-friendly technologies using detailed patent data from 96 countries for the period 1995–2007. The data provide strong evidence that lax Intellectual Property regimes have a strong and negative impact on the international diffusion of patented knowledge. Restrictions on international trade and foreign direct investment also hinder the diffusion of climate-friendly technologies. Surprisingly, local technological capabilities tend to discourage transfers. While broad indicators of technology capabilities are expected to facilitate transfers, this latter result stems from our technology-specific definition of local capabilities, which makes it possible to capture a substitution effect between local and foreign inventions.  相似文献

Diffusion of new technology is an important driver of economic growth. In this paper, diffusion of mobile telephony in India is studied. There is a vast diffusion potential in this country which needs to be exploited efficiently and in a rational way. This paper investigates the social, technological, economical and political (STEP) factors that have influenced the diffusion process of mobile telephony especially the diffusion speed. The epidemic model, which is widely employed in the diffusion studies of mobile telephony, is used for the study. The data is fitted into logistic, gompertz, and bass models by nonlinear least squares and it is found that gompertz model best describes the diffusion process of mobile telephony in India. The study reveals that competition and government intervention played a significant role in accelerating the diffusion speed of mobile telephony by making the technology affordable. It is found that mobile telephony is a substitute for fixed line telephony in India. The findings will be useful in taking managerial decisions with respect to factors in forecasting and controlling the diffusion process of emerging technologies.  相似文献

Despite a well-developed literature on implications of multimarket contact among firms for performance in domestic markets, only recently has theoretical and empirical work turned to similar issues in international trade. In this paper, I consider the possibility that exporters meeting rivals in multiple markets will be reluctant to enter (via exports) the home markets of those rivals. Empirical results using trade data (during 2007–2010) for the fats and oils industry support this hypothesis.  相似文献

新技术的扩散总是涉及到时间和空间两个尺度,相当一部分技术扩散研究只研究时间这一尺度。相比而言,空间的扩散过程及机理的研究就困难得多,这不仅因为数据难以获得,而且因为在空间尺度上影响扩散的因素也相当复杂。文章利用文献计量方法获得有关GIS技术在中国教育科研机构的基本数据,为技术的时空扩散研究提供了难得的数据资源。该数据的特点在于同时具有时间和空间两维尺度。数据表明,无论是在时间还是在空间尺度上,技术的扩散都表现为经典的S型增长路径。在数据的基础上分析了影响GIS扩散的主要因素,包括地区文化教育和科研状况、地区经济发展以及地区信息与网络状况等。在此基础上,利用主体模型对时空扩散过程加以模拟,模拟的结果比较令人满意,表明对于影响因素的分析是可靠的。  相似文献

提高创新效率和人力资本投资效率,采取渐进式技术进步以及经济危机的爆发和环保要求的提高等等,都可以激励企业家创新和劳动者的人力资本投资,使人力资本与技术进步形成一个良性循环,这决定了技术进步型经济增长的实现。随着创新和人力资本投资的不断进行,生产模式将不断更新,那么前后相继新旧生产模式的生产曲线的包络线就构成了经济增长的路径。发展中国家依靠技术模仿,可以发挥"后发优势"而实现短期高速增长,但是这种增长模式很难持续。采用技术模仿与技术创新相结合的技术进步方式,才是发展中国家实现长期增长和经济赶超的最佳策略。  相似文献

Abstract. In this paper we test the homogeneity of the technological parameters among OECD countries, which is the maintained hypothesis in most of the empirical growth literature. We first identify differences in the constant term of the convergence equation estimated for the OECD 1960/1990 sample using a fixed- effects estimator. Then we provide a formal test of the homogeneity of technological parameters across groups of countries. We identify at least two different groups within the OECD, with significantly different technologies. Convergence within each group is fast, supporting the notion of club convergence. Nevertheless, the implausible parameter values obtained for the leading technology club casts some doubts on the validity of the Solow model to account for the long run behaviour of this group of countries.  相似文献

The paper proposes a distinction between the two dimensions of convergence—within and between countries—when analyzing the impact of cross‐border outsourcing on real wage rates in the EU‐15 and the CEEC. In the CEEC, international outsourcing has not affected the adjustment of average real wage rates at the manufacturing industry level, but it has led to a closure of the gap within a typical EU economy. Between‐country convergence is likewise fostered by cross‐border outsourcing, supporting the hypothesis that outsourcing facilitates international factor price equalization.  相似文献
