“比较优势陷阱”与中部地区经济增长

就地区经济增长而言,丰裕的自然资源既存在比较优势的促进作用,又存在比较优势弱势化的约束作用。因而自然资源对中部地区经济增长的影响,不仅要看到其促进作用,更要关注其约束作用。中部地区既要充分发挥自然资源的比较优势,更要消除其约束作用,促使经济健康快速发展。

Is There a ＂Middle-income Trap＂？ Theories, Experiences and Relevance to China

Through review of relevant studies and analysis,this article indicates that the "middle-income trap " is in line with the framework of the mainstream economic growth theories, and,therefore,it is a useful concept through which we can analyze economic growth phenomena in specific economic growth phases.The empirical experiences of many countries also indicate that at specific middle-income stages,economies with high rates of growth tend to encounter economic slowdown or even stagnation.The article shows that China is facing the challenge of determining how to move smoothly beyond the middle-income stage of economic development,while taking into account the shifting population structure,changing resource endowment and growth patterns.The article,drawing on international experiences, puts forward several policy suggestions relating to improvement in total factor productivity, expansion of human capital accumulation and deepening of system and government function reforms.

Agricultural Productivity Growth and Escape from the Malthusian Trap

Industrialization allowed the industrialized world of today to escape from the Malthusian regime characterized by low economic and population growth and to enter the post-Malthusian regime of high economic and population growth. To explain the transition between these regimes, we construct a growth model with two consumption goods (an agricultural and a manufacturing good), endogenous fertility, and endogenous technological progress in the manufacturing sector. We show that with an exogenous increase in the growth of agricultural productivity our model is able to replicate stylized facts of the British industrial revolution. The paper concludes by illustrating that our proposed model framework can be extended to include the demographic transition, i.e., a regime in which economic growth is associated with falling fertility.     

规模经济、产品差异化与中国入境旅游空间结构的变动

本文研究了1986年至2005年中国入境旅游空间结构的变动情况,并对两类入境旅游集中的典型地区的旅游发展路径进行了剖析.研究认为,中国入境旅游在总体趋于分散的背景下,也存在着两个明显的集聚现象.第一,长期以来入境旅游在传统旅游热点地区高度集聚;第二,云南成长为新的集聚中心.对于前者的解释是,良好的旅游基础设施和接待设施、较高的知名度使传统旅游热点地区在改革开放之初就进入了一个动态的、自我发展的良性循环.对于后者的解释是,极具地方特色的差异化旅游产品的开发与营销以及政府主导下的大规模的旅游基础设施建设使云南旅游成功地实现了从"低水平陷阱"向"自我发展的良性循环"的"惊人一跃".     

A green Lewis development model

This paper develops an environmental extension of a Lewis dual economy model, in which the interaction between environmental quality and economic growth, in one of its several dimensions, is explicitly modeled to explore long-run effects of a pollution abatement rule in developing economies. The government requires the modern sector to dedicate a fraction of its output to pollution abatement, with such profitability-reducing fraction being endogenous to the level of environmental quality. Meanwhile, the level of environmental quality positively affects labor productivity, profits and, therefore, savings, which has a positive impact on capital accumulation. It is shown that this pollution abatement requirement, by affecting profitability in the modern sector both negatively and positively, makes for the emergence of an ecological development trap from which a developing dual economy, if left to the free play of its structural forces, never escapes. Fortunately, however, this economy can be released from such a trap not only through a standard Big Push, in the spirit of Rosenstein-Rodan, but also by means of what we call an Environmental Big Push.     

Can East Asia rise again?

In recent times, the economies of East Asia have been confronted by two major economic recessions, the first caused by the East Asian financial crisis, and the second by the slump in the ‘new economy.’ The causes of these two recessions, their scope and their influences differ significantly and during these periods of economic downturn the economies affected have adopted various monetary policies aimed at reducing interest rates and tax rates, and pursuing the expansion of government expenditure. However, these policies have obviously not yet been as effective as expected.This paper sets out to determine those factors affecting the possibility of East Asia rising again from the recent economic slump, a slump which has stemmed from excessive investment in the electronics and information industries. The paper begins with an overview of the East Asian economy, with particular reference to the recent serious decline following the steady recovery from the East Asian financial crisis and a review of the measures taken to counter it. Proposals are then made with regard to a number of lessons to be learned from the recent slump.There are three major issues involved in the question of whether East Asia can rise again from the current economic slump. First of all, many of the economies of East Asia have tried their utmost to upgrade their industrial structures from labor- to technology-intensive, or towards a knowledge-based economy and, to some extent, have actually been quite successful in achieving their goals. Secondly, almost all of the East Asian economies have paid particular attention to educational development, with many families having sent their children to foreign countries to receive advanced education in the hope that when they return they can make a substantial contribution to the progress of their home economies—examples of this trend are provided by Taiwan and India. Thirdly, there are abundant natural resources in East Asia along with rich sources of manpower with a hard-working spirit; these two factors can create comparative advantages and strengthen the competitiveness of these economies.In view of the recent developments towards regionalism, it is imperative for the economies of East Asia to form an East Asian Community in the near future, and many of the economies in this region are currently endeavoring to realize this vision, despite many obstacles still facing East Asia which will ultimately need to be overcome.     

论技术创新驱动经济发展效率决定的国家经济状态

从技术创新与进步促进投资效率的角度,建立一个经济增长与技术进步相互促进的微分方程组模型,求解后可以得到持续经济增长以及低、中、高收入陷阱的产生条件。结果表明：对于研发效率、研发投入占国民收入的比重以及研发成果驱动经济效率较高的国家,其经济更容易实现持续增长;而对于无法满足持续增长条件的国家,其国民收入存在理论的最大值,这意味着其经济发展最终将会陷入停滞并陷入对应的经济增长陷阱。
