Abstract: Proceeded from significance of industrial structure adjustment and water use efficiency control to the Hydrosocial-Cycle regulation, the present work, takes Yancheng City, a typical area in Jiangsu Coastal District as case study region where the nonlinear programming model is proposed by using Logarithmic Mean Divisia Index approach and mathematical programming method to study regional socio-economic water consumption regulation strategy. The model contains the constraints on total water-use quantity limit, water-use efficiency and quantization equations of driving factors decomposition effect. It also takes full account of socio-economic development at present situation and plan, water resources utilization strategy and target plus saving-water society construction planning. For analysis period of 2010 to 2016 year, the rational scheme on Yancheng City's socio-economic development size, industrial structure proportion and water resources utilization efficiency is obtained by solving the model. According to computation results corresponding to water utilization, industrial structure, economic development level and population scale, the characteristic of driving factors effects are analyzed, as well adjustment policy of the primary industry, secondary industry and tertiary industry, and water consumption regulation measures were drawn out
