Conclusions of the research are summarized as follows: (1) the arable land had been continuously de-creasing from 1996 to 2005, with a loss of 1,708,700 hm 2 and an average decrement of 170,900 hm 2 per year; (2) land for construction increased 1,373,700 hm 2, with an average increment of 153,200 hm 2 per year; (3) total area of encroachment on arable land for con-struction between 1996 and 2005 was 1,053,100 hm 2, accounting for 34.03% of the arable land loss in the same period, the percentages of which used for industrial land (INL), trans-portation land (TRL), rural construction land (RUL) and town construction land (TOL) are 45.03%, 15.8%, 15.47% and 11.5%, respectively; and (4) the fluctuation of the increase of construction land and encroachment on arable land in the area were deeply influenced by the nation’s macroscopic land-use policies and development level of regional economy. The growth of population and advancement of technology promoted the rapid industrialization, construction of transportation infrastructures, rural urbanization and expansion of rural set-tlements in the eastern coastal area, and therefore were the primary driving forces of land-use conversion.Keywords: urban-rural harmonious development; rural urbanization; new countryside construction; arable land loss; the eastern coastal China1 IntroductionWhile urbanization is a necessity in the process of modernization, it should not be the ulti-mate objective of rural social and economic development. Instead, to transform the “dual track” structure and realize urban-rural integration should be the long-term goal of China’s new socialist countryside construction and urban-rural balanced development (Wang, 2004). Since land resource is the physical base of social and economic development, land supply, a major tool of the government to regulate the land market and macro economy (Shi and Qu,
