摘　　要：运用行业集中率指数和赫芬达尔指数计算我国城市水务产业的集中度,结果表明,目前我国城市水务产业集中度相对较低。从产权视角分析了计算结果:①我国城市水务产业集中度相对较低,这主要是由于市场划分的视角不同造成的,认为以全国市场为视角分析我国城市水务产业集中度更为合理;②国有水务企业依靠规模竞争力获取的市场份额,更多的是来自于政府的扶持;③产业集中度不仅依赖于企业规模,还需要依靠企业的竞争实力;④我国城市水务产业处于国有企业主导的垄断竞争市场,但国有企业规模优势产生的市场垄断地位正在逐步削弱。The concentration degree of the urban water industry in China was calculated by use of the industrial concentration ratio index and the Herfindahl index.The results show that the concentration degree of the urban water industry in China is relatively low.From the perspective of property rights,(1) it is mainly caused by different perspectives of market segmentation,and it will be more reasonable to analyze the concentration of the urban water industry from the perspective of the whole China's market;(2) the market share of state-owned water companies depending on their competition scale mainly comes from the government support;(3) the industrial concentration degree depends on the scale and the competitiveness of enterprises;(4) in China the urban water industry is in state-owned enterprises-leading monopolistic competition market,but the market dominance produced by the scale advantages of state-owned enterprises is gradually reduced.
