This study intends to assess operation and maintenance (O&M) performance of irrigation infrastructure of 8/11 provinces of Red River Delta by using the input-orientation model of non-parametric data envelopment analysis (DEA) with hypothesis of constant return to scale (CRS) and variable return to scale (VRS). Data of 8 input variables is O&M cost categories and an output variable is irrigation areas converted to paddy areas from 2014 to 2016. The study estimated optimal efficient scores of CRS and VRS being 0.86 and 0.98 in respectively, similar to much waste of financial cost resources by 14% and 2% in respectively. Concurrently, input cost slacks are obtained from CRS and VRS calculation and then determining the efficient input target (EIT) for optimal cost structures estimation. In which, the labour cost is the highest percentage, occupied 48,97% and 47,70% by models. Allocation of financial cost by these optimal structures according EIT-CRS or VRS will also positively impact on improvement of O&M efficiency of irrigation works per a cost unit by 148.7% and 105.03% in respectively. These are the significant base for recommending policies of irrigation subsidy and incentive the private participation partnership in irrigation sector.
