[摘　要]　对全国历年城市市政公用设施固定资产投资情况、城市道路和桥梁情况、乡公用设施情况、村庄公用设施建设和投资情况进行了实证比较，由此发现：城市市政公用设施固定资产投资规模和城市市政公用设施的实物存量，近年来都呈现明显增加的态势；乡级道路桥梁的实物存量呈现下降态势；村庄公用设施的资金投入呈现增加态势，但村庄道路桥梁的实物存量变化不大。结论是：我国基础设施建设和资金投入的城乡二元特征明显，须对农村基础设施建设加大投入力度，并提升资金使用效率。

Abstract: This paper studies inventory status and investment in urban, township and village infrastructure, and makes a comparison. It is found both the scale of investment and the actual inventory of urban public infrastructure have trended up significantly; the actual inventory of township's roads and bridges has trended down; the investment in village's public infrastructure has increased significantly, while the actual inventory of village roads and bridges has not increased obviously. The dualization characteristic between urban and rural area is apparent, it is urgent to increase the investment scale in rural infrastructure, and to improve investment's efficiency.
