Abstract: This paper approached the correlating mechanism between economic development and land consolidation projects based on the system analysis of the land consolidation project implementations and the spatial differentiation in Chongqing City. Results indicated that according to the different newly increased cultivated land rate, land consolidation projects on the district or county level could be divided into four categories: land consolidation, cland consolidation and exploitation, land development and consolidation, land development. While according to the investment per unit area on newly increased cultivated land, it could also be divided into four categories: high investment, reasonable investment, partial low investment and low investment. Correlating curve type among the investment per unit area in newly increased cultivated land, average annual growth rate of GDP and average annual growth rate of per capita GDP was a compound one. Correlations among newly increased cultivated land investment per unit area and annual growth rate of per capita GDP, annual growth rate of per capita GDP and other economic development indexes showed an “S” changing tendency curve. The construction standards of the land consolidation projects on district or county level investment were not well linked with its economic development, and the growth speed of the investment quantity on newly increased cultivated land was reduced. The implementation scale of land consolidation project on agricultural land and basic farmland was increased while the investment on newly increased cultivated land was reduced. This paper studies the correlating rule between the development of Chongqing economic and the land consolidation for enhanced and sustainable development of Chongqing land consolidation theory.
