China's Economic Prospects and Sino-US Economic Relations

引用

China & World Economy 2006年第2期14卷 45-55页

作者： Pingfan Hong Principle Economic affairs officer and Chief for Global Economic Monitoring Department of Economic and Social Affairs United Nations.

A better comprehension of the mixed sentiment in the rest of world towards the rapid rise of the Chinese economy will depend on the understanding of some key features of the Chinese economy, such as those associated with its size, structure and institution. To further sustain its high growth, China is facing more challenges than it has encountered in the past 2 decades, including a gamut of material constraints. Although polices and technological progress might alleviate many of these constraints, the ultimate solution will still lie in continued institutional reform. China＇s recent move towards a more flexible exchange rate regime is in line with its broad reform and in accordance with the progress of its development. However, such a move will have limited immediate effects on the prodigious US trade deficit, which itself is a problem rooted in the flawed international reserve system, far beyond a Sino-US trade issue.

Trade Balance: Numbers Can be Deceiving

引用

China & World Economy 2006年第3期14卷 54-70页

作者： Yuefen Li Senior Economic affairs officer United Nations Conference on Trade and Development （UNCTAD）

Trade disputes have become more prevalent and acute in recent years. Almost all center on bilateral trade balance and/or market access of certain merchandise or services. However, since at least the mid 1980s, affiliate sales have become a more direct and more powerful form of market access than the traditional cross-border commercial transactions for developed countries, whereas developing countries still rely predominantly on traditional trade. The importance of the international production supply chain is increasing with a bias against downstream producers. The current data collection and compilation system of trade balance can not reflect these changes in the world economic environment. It overstates exports of developing countries and understates their imports. None of the countries in the world can illustrate the weakness of the conventional system better than China.
