The study is to assess the economic efficiency of land use types and evaluate the land suitability as a basis for land use change in Cai Rang district. The methods of household interview, soil survey and land evaluation (FAO, 1976 & 2007) were used to implement this study. The result showed that the studied area had 4 land use types such as: double rice crops (LUT 1); rice upland crops (LUT 2); upland crops (LUT 3); fruit trees (LUT 4). The land evaluation has determined that in the studied area there are 21 land mapping units and 8 suitable zones for land use types. About physical evaluation, excepting zone VIII was non suitable for all LUTS, other zones were marginally suitable to highly suitable for all LUTS, in which zone I, II were highly suitable for all LUTS. However, if the acid sulphate soils were improved, almost zones were moderately suitable to highly suitable for all LUTS. The result of economic evaluation indicated that the upland crop and fruit trees had higher benefit than double -rice crops. About quantitative land evaluation, only LUT 1 had marginally suitable to non suitable on benefit and cost benefit for all zones, almost LUTS were moderately suitable to highly suitable on benefit and cost benefit. Proposals are that double - rice crops should be placed at zones III, VI, VIII; rice - upland crops should be placed at zones V, VII; upland crops should be placed at zones IV, VII and fruit trees should be placed at zones I, II, IV, VI, VIII
