试论我国出口市场多元化战略实施

出口市场多元化应包括四个方面的内涵:首先,市场多元化是指区域多元化,即出口市场应全方位、多角度分布于世界各地,而不仅仅聚集于少数市场;其次是指商品多元化,因为商品是市场的核心内容,一国对外贸易,不单单是点多、面广,而且商品品种、规格、档次等都要多样化,才能符合不同消费层次的需求;第三,出口市场多元化应包括经营手段的多样化,即开拓海外市场要采取灵活多变的方式、方法。

Different Roles of Land in Rural-Urban Migration： Evidence from China＇s Household Survey

This paper explores the influence of land holding on rural–urban migration using China's 2008 household survey data. It shows that the contradictory findings of existing published literature can be explained by introducing a migration distance variable. The empirical studies show that land holding plays a different role in short‐distance and long‐distance migration. Land holding has a U‐shaped curve association with the probability of short‐distance migration and has an inverted‐U‐shaped association with the probability of long‐distance migration. Therefore, the government needs to provide more job information and migration subsidies to farmers who have little land to overcome difficulties in the process of migration so as to reduce rural–urban inequality.

地区间主义的两种形式——基于欧盟与中国对非地区间合作经验的分析

地区间主义研究的核心问题是地区间制度设计在促进合作上的适用性。制度化与论坛化是当前地区间合作中的两种主要形式,这两种制度选择的区别体现在结构平衡、施动方向、互动结果以及由此所决定的制度适用性上。作者提出:在制度化的地区间合作中,强势的一方因为缺乏足够的回应或制衡,将导致其倡议和政策制定主要从自身角度出发,这在很大程度上削弱了政策和举措的适用性。而在论坛化的地区间合作中,平衡和双向的互动以及合作的意愿能够增加最后的政策和举措的适用性。欧盟推动的对非制度化地区间合作与中非合作论坛推动的论坛化地区间合作是当今地区间主义比较有代表性的案例。通过对欧盟与中国的对非地区间合作的比较研究发现,适用性的制度设计应该建立在地区间结构平衡、双向互动和强烈的政治意愿基础之上。     

China＇s ApprOach to Rebalancing： A Conceptual and Policy Framework

This article seeks to develop a conceptual and policy framework for understanding China’s role in the global economic imbalances.China’s contribution to these imbalances via recurrent trade and financial surpluses corresponds with a phase of deepening structural risks to China s economic growth and development.These structural challenges include:the composition of growth resulting from China’s dynamic internal transformation,China’s trade orientation,the trajectory of resource use and Commissions,welfare problems relating to distribution and international constraints.This article develops a conceptual framework for examining the relationship between the processes of long-run structural transformation in China,its economic imbalances,and the role of institutional reform in dealing with these structural challenges.As such,economic policy should extend beyond short-term macro management to pursue an institutional reform agenda to facilitate broader structural change to mitigate constraints to future growth and to improve economic welfare.     

China＇s Economic Growth： International Spillovers

China's economic development since 1978 is one of the most significant events in recent history. Many aspects of this development have been extensively analyzed in the published literature. However, the implications of China's growth for other countries have been relatively neglected. The present paper attempts to fill this gap in the literature. The paper first presents some facts on China's role in the world economy, and then measures the impact of China's growth on growth in the rest of the world in both the short term and the long term. Short‐run estimates based on vector autoregression and error correction models suggest that spillover effects of China's growth have increased in recent decades. Long‐term spillover effects, estimated through growth regressions based on panel data, are also significant and have extended in recent decades beyond Asia. The estimates are robust to the effects of global and regional shocks, changes in model specification, and sample period.     

对制定外贸出口产业政策的方针、原则和重点的探讨

<正> 所谓产业政策,是指政府对产业的均衡及其发展所采取的政策。产业政策是以产业结构的高层次化和合理化为基本目标,这说明产业结构政策在产业政策体系中处于核心地位。出口产业政策涉及生产出口商品的这部分产业。一国的外贸政策取决于该国的出口产业政策,也就是说,外贸政策的制定,必须与出口产业政策互相保持协调和一致;而出口产业结构和贸易结构的确定又必须首先考虑国际市场需求结构的变化。从二次大战后日本、南朝鲜等国家和地区对出口商品结构及其
