Abstract
Taking 18 cities of Henan Province as research samples,the evaluation index system of urban land use efficiency was built,using data envelopment analysis (DEA) model,the land use efficiency in 18 cities in 2009,2012,2015 was studied.The results showed that:regional mean of land use efficiency in 2009,2012,and 2015 were 0.957,0.961,0.976,indicating that the efficiency of land use of Henan Province overall level is higher and the difference is not significant.Many factors influence efficiency of land use,among which,the fixed assets investment and construction land area exists input redundancy,high-centralized industry practitioners are spending too much,environment is output benefit relatively insufficient.Most of the city scale was in a state of decline in 2009,the number of cities in scale increasing stage was gradually increase during 2012-2015.The urban land use spatial distribution present central high edge low efficiency,the pattern of the western region of northeast high low,and the effect of small scale level.Rational allocation of inputs improvement loose inefficient way of land use is very important to improve the efficiency of land use of Henan Province.关键词
