為配合政府檢討自來水事業民營化第一階段工作之解除管制，本研究以省水公司與北水處為對象，探討「我國自來水市場解除管制可行性」。研究結果顯示，國內主要二個自來水事業單位為台灣、省自來水股份有限公司 (省水公司) 及台北自來水事業處 (北水處)，其組織型態相異，分屬國營會之公司法人及台北市政府一級事業機關。北水處須經台北市議會同意且自來水事業屬地方公共事務，故北水處不願意參與市場結構重組。國外自來水事業僅英國採拋售股權於全國實施民營化。美國、澳洲、日本等國業皆尚未於全國實施民營化，以大都市採公有民營、公民合營方式 (非氏營化)，以提高經營效率、服務品質及減少政府財政負擔。 自來水事業上游 (水源開發、取水) 乃以公營為主，中、下游則可導入公有民營、公民合營或全面民營化。自來水事業解除管制之第一要務為水價合理化，以利於推動中、下游之公有民營、公民合營或全面民營化。此外，應依自來水水法第十三條，考慮水源流域與經濟規模分析，重新條檢討國內分區經營之劃定，以增進競爭機制。我國自來水事業於近、中程應檢討並擴大委託民間經營管理之業務範園，可先推動公有民學或公民合營方式，研訂其相關管理監督辦法，視其成效再決定推動全面民營化時機。

To coordinate with the government in its review of the first phase in the privatization of the water industry which is deregulation, this research is undertaken by the Taiwan Water Supply Corporation and the Taipei Water Department to probe into the Feasibility Study on the Deregulation of the Public Water Industry Market in Taiwan”. The former is a state-operated corporation under the control of the state-operated corporation, while the latter is subordinated to the Taipei Municipal Government. Thus, any action on the part of the Taipei Water Department requires the approval of the Taipei City Council because the water industry is considered a local public affair; as far as its benefits are concerned, unlike the Taiwan Water Supply Corporation which has a financial deficit, the Taipei Water Department is unwilling to participate in reforming the structure of the market. With reference to experiences from other countries, a British enterprise, for instance, is the only water supplier that sells in large quantities to the whole nation, and it has been bringing privatization into effect. Other countries, like the USA, Australia, and Japan, have not yet started to do so, but they are have, nevertheless, begun to adopt measures such as Build-Operate- Transfer (BOT) or the collaboration of the government and local people operating together to increase operating efficiency and the quality of service, and reduce government expenditures. There, the upper courses of the water industry (water resources development) are mainly operated by the government, but the mid- and lower courses might be led by the BOT, which is the collaboration between the government and private companies, or the Build-Own-Operate (BOO) system. However, as their first mission in deregulation, it is required that the water industry consider making the price of water reasonable. In addition, according to Article 13 of the Water Supply Law, the analysis of the basins of water sources and economic scale should be taken into consideration, and the plan for domestic regional operations should be reviewed so as to improve the mechanism of competition. In the short and mid-term, the local water industry should either review and expand the scope of the business authorized to private companies, or further develop the BOT system, or the government should cooperate with private companies, drawing up relevant means of management and supervision, and in the end, deciding on the optima Timing-- depending on the effects-- to encourage privatization.
