This title was first published in 2001. The 1980s and 1990s were not only a period in which many developing countries adopted a series of major economic policy reforms, but also an era in which all socialist countries undertook varying degrees of radical reforms in their Soviet-style central-planning economic management systems. This volume examines the performance of China's industrial reform and open-door policy during the period of 1980-1997 through conducting a case study on one of its Special Economic Zones (SEZs), Xiamen. It adopts an analytical approach - examining Xiamen's performance from the perspective of three important interactions: between the country's general economic reform policies and the Special Policy implemented in the SEZs; between the Xiamen SEZ and the vast Chinese hinterland; and between foreign (especially Taiwanese) direct investment and local industrial transformation.

Much work went into preparing a program of high quality. We received about 972 submissions. Every paper was reviewed by 3 program committee members, about 382 were selected as regular papers, representing a 39% acceptance rate for regular papers. The CCCM conferences serve as good platforms for the engineering community to meet with each other and to exchange ideas. The conference has also stroke a balance between theoretical and application development. The conference committees have been formed with over two hundred committee members who are mainly research center heads, faculty deans, department heads, professors, and research scientists from over 30 countries. The conferences are truly international meetings with a high level of participation from many countries. The response that we have received for the congress is excellent. This volume contains revised and extended research articles written by prominent researchers participating in the conference.

This paper investigates the impact of political interventions made by Beijing and Taipei in recent years on the development of cross-Straits economic relations. The study finds little evidence that either the missile firings carried out by Beijing in 1995 and 1996 or the mainland policy review conducted by Taipei since 1996 has slowed down the growth of trade and investment activities between mainland China and Taiwan. In fact, the trade dependence ratios for the two economies have continued to increase since 1995. Although the level of Taiwans committed investment in the mainland has dropped considerably in recent years, it has moved largely in line with the general trend of total FDI in China. The synchronism between Taiwan investment and other foreign investment suggests that the Taiwan investors, like other foreign investors, responded mainly to macroeconomic conditions and policies in the mainland, rather than to the directives from the Taiwan authorities, when they made their investment decisions. This is due to the fact that the economic logic of pursuing cross-Straits economic activities is so powerful that Taipei's restrictive policy toward investment in the mainland has often been ignored or diluted by the Taiwanese private business community.
