The common goal of all the reforms now underway in the CAS system is to promote the S&T cause. As the external situation of the S&T development in China changes, it becomes necessary for the CAS to adopt counter-measures to respond accordingly. This article gives an overall exposition, ranging from a review of the significance of the current drive towards structural readjustment in the CAS, to its main contents, expected targets, principles and the selection of possible options, in addition to a number of concrete suggestions and tentative ideas aired by the author of this article for the on-going drive.Based on the deepening development of the current and full-scale reform drive in the Academy, the CAS leadership had put forward a plan for carrying out a structural readjustment program across the CAS system. To promote this new move, here I would like to offer some of my personal opinions and tentative ideas. 展开更多

At present,China is facing rapid economic and social development as well as the shortage of land for construction. In fact,various countries and regions are faced with similar problems in the process of urbanization and industrialization,and the land readjustment is often adopted for construction land consolidation to promote economical and intensive land use and solve the supply and demand conflict of construction land. Based on the land readjustment experience of Germany,Japan,China Taiwan and South Korea,we perform a comparative analysis on the implementation background,concept,purpose,procedures and core principles,and borrow ideas from their experience,in order to provide a reference for China to adopt suitable land readjustment tools during construction land consolidation. 展开更多

Since the disintegration of the former Soviet Union, the United States and Rus-sia have gone through a tortuous road in forging their post-Cold War relation-ship. At present, they are neither bipolar rivals, nor strategic partners as initiatedin early 1990s. They have instead turned from maintaining amicability into copingwith the reality. Their discrepancies in terms of strategies and bilateral relationshave emerged one after another in recent years and became intensified especially af-ter Operation Desert Fox against Iraq by the United States and Britain 展开更多
