中国进口与经济增长关系的区域差异分析

利用面板数据对中国东、中、西部的进口额和GDP增长关系进行的实证研究。在短期内，GDP增长对进口额影响最小是中部地区，在长期，西部GDP增长对进口额影响最大。中国经济增长对拉动世界经济增长起了十分重要的作用，中国经济增长减速也会影响全球经济。     

Addressing the growth failure of the oil economies: The role of financial development

The oil exporting countries have experienced a relatively continuous fall in GDP per capita over the last 30 years. This is in spite of benefiting from a more than average of the rest of the world investment rate. The findings of this paper, report a lower level of financial development for the oil economies when compared with the rest of the world. We will show in this paper that the higher rate of investment of the oil economies can be explained mainly by the oil revenues and surprisingly, financial development has a net dampening effect on investment for these economies. The paper also shows that the weakness of financial institutions, contributes to the poor performance of economic growth of the oil economies and the weakness of financial institutions might be associated with the dominant role of government in total investment and the weakness of private sector.     

Are Venture Capitalists a Catalyst for Innovation?

In this paper we test two hypotheses concerning the presence of innovation in venture capital investments and the growth of innovative venture backed firms. To examine these hypotheses we considered sample of 37 Italian venture backed firms that went public on the Italian Stock Exchange between 1995 and 2004 and by a statistical matching procedure we picked 37 twin firms among the non‐venture backed IPOs for the same period. Our evidence shows that innovation is an important factor during the selection phase but once the investment is made, the company does not promote continued innovation and concentrates all efforts to improve other economic and managerial aspects.     

浅谈假日经济对中国经济的长期拉动效应

假日经济已成为国民经济的重要组成部分,并在国民经济中发挥着日益重要的作用。但在假日经济的发展过程中,也出现了一系列的负面效应,影响了假日经济的持续发展。文章就如何发挥假日经济的长期拉动效应,提出了相应的对策。     

经济增长、要素投入与发展战略选择——对我国经济增长的长期机制的实证分析

中国经济增长的长期机制问题一直以来都是理论界研究的热点问题。文章通过对1953—2004年与经济增长相关因素的统计数据的回归分析,并结合其他学者的研究成果,认为支撑我国经济增长的长期动力主要来自于要素投入,而要素投入的效果却与经济发展战略制定的一些非经济因素有关。     

现代服务业：上海经济增长的新动力

本文通过经济增长弹性与就业弹性两个指标,对上海"十一五"规划中提出将优先发展的现代服务业及其主要子行业在上海经济增长中的作用进行了研究。分析认为目前上海第二产业与第三产业对经济的拉动力相当。而现代服务业的拉动力大于传统服务业。近年来,现代服务业的就业弹性均值较大,同时弹性的波动变化很大,这是上海GDP就业弹性近几年波动增大的主要原因。同时,通过对现代服务业中主要子行业的分析,发现现代服务业子行业间就业弹性的变动有着高度的正相关,这将增加现代服务业就业弹性波动对于上海GDP就业弹性波动的影响。     

教育、人力资本投资与经济增长——广东省和四川省的比较研究

人力资本在社会经济发展中具有基础性、战略性的作用。而教育是人力资本投资,提高人力资本质量的重要途径。本文利用生产函数分析比较广东省和四川省经济增长过程中人力资本投资对经济增长的产出弹性以及贡献率,实证了人力资本是经济增长的重要决定因素,并对教育和经济发展的关系做出较为全面的解释,对四川省的经济发展提出政策建议。     

Productive Efficiency of the Swine Industry in Hawaii: Stochastic Frontier vs. Data Envelopment Analysis

Improving productive efficiency is an increasingly important determinant of the future of the swine industry in Hawaii. This paper examines the productive efficiency of a sample of swine producers in Hawaii by estimating a stochastic frontier production function and the constant returns to scale (CRS) and variable returns to scale (VRS) output-oriented DEA models. The technical efficiency estimates obtained from the two frontier techniques are compared. The scale properties are also examined under the two approaches. The industry's potential for increasing production through improved efficiency is also discussed.     

An Average Derivative Estimation of Stochastic Frontiers

This paper utilizes the average derivative estimation of Stoker (1986) and the pesudo-likelihood estimation of Fan, Li, and Weersink (1996) to estimate a semiparametric stochastic frontier regression, y = g(x) + , where the function g(.)is unknown and is a composite error in a standard setting. The proposed semiparametric method of estimation is applied to data on farmers' credit unions in Taiwan. Empirical results show that the banking services of the farmers' credit unions is subject to economies of scale, but high degree of cost inefficiency in operation.     

Localized Innovation and Productivity Growth in Asia: An Intertemporal DEA Approach

Recent contributions to growth theory stress the importance of localized innovation for the performance of more backward countries. In earlier papers, analyses by means of DEA techniques confirmed this intuition. In this paper, we extend this type of analysis by relaxing the macroeconomic viewpoint adopted until now. New databases on output, labor and capital input in the agricultural and manufacturing sectors are developed for 40 countries. Using intertemporal DEA, it is found that changes in the global production frontier are localized at high levels of capital intensity. This result is stronger in agriculture than in manufacturing. Further, a decomposition of labor productivity growth in eight Asian countries for the period 1975–1992 into the effects of capital intensification, learning and innovation is made. The results suggest that there is a particular development path in which increases in capital intensity appear to be a prerequisite to benefit from international technology spillovers.JEL Classification: O14, O30, O40, O47
