China＇s Regional Disparity and Its Policy Responses

The fruits of China＇s rapid economic development over the 3 decades have not been distributed fairly across different regions. Using data from a sample of 815 Chinese listed firrns during 1998-2004, our error-correction investment model showes evidence of different financial constraints on firms＇ investment in different regions. We argue that China＇s regional development policies have contributed greatly to the regional inequalities. To control the rising inequality, China has shifted its focus from the coast to the interior regions. However, it is becoming increasingly difficult for the government to direct the economy, as market mechanisms now have afar greater influence on the economy than the government does. The people-centered approach of the current leadership has meant that substantial attention has been placed on regional development disparities in an attempt to build a ＂harmonious society. ＂ China needs further extensive reforms if all the measures for reducing regional disparity are to be effective.

The Political Economy of Exchange Rate Regimes: Evidence from Hong Kong and Taiwan

This paper investigates whether the macroeconomic performance of a small- open economy depends on the choice of exchange rate regimes. Hong Kong and Taiwan - two economies with many similar macroeconomic characteristics, but different in their choices of exchange rate regimes - provide a good setting to study the relation between the choice of exchange rate regime and macro-economic performance. We examine the basic facts of growth and inflation and the coefficients' stability of their vector autoregression (VAR), as well as cyclical characters of other aggregate variables in Hong Kong and Taiwan. Our empiric finding indicates that macroeconomic performance is not systematically related to exchange rate regimes.

美投资银行的竞争优势及对内地投资银行业的冲击——基于波特钻石理论和动态企业能力论视角

在金融业全面对外开放的条件下,中国脆弱的投资银行业面临新一轮的挑战,被外国投资银行攻城掠地的场面是否会在中国继续上演?对此,波特的钻石理论提出了使一个国家具备产业竞争优势的六个因素,但真正使一个国家产业具备竞争优势却在于企业内部的组织学习和创新.美国投资银行业基于长期对生产要素的投资和积累形成了全球性的竞争优势,占据了投资银行高端业务并有进一步争夺中国投资银行业务的趋势.面对冲击,国内投资银行应立足自身优势,发展壮大自己,而政府也应在产业规制和健全宏观环境上下功夫.
