自然垄断产业内的民营化改革是一个制度创新的过程,其目标是通过民间资本参与自然垄断产业的投资和经营,增加自然垄断产业的投资,增强产业内的竞争性,提升自然垄断产业企业经营效率和改善产业分配效率。我国城镇自来水产业从20世纪90年代开始了民营化改革,但改革取得的成效如何还缺乏系统和定量的研究。本文从静态效率和动态效率两个方面,采用C-D生产函数检验了广东省自来水产业内不同产权类型企业的绩效差异,结果表明,对自然垄断产业的民营化改革应以打破垄断、促进竞争和产权改革并举,才能取得明显的成效。

Its goal is to increase the investment in the natural monopoly industries, increase the competitiveness in the industry, and improve the operation of natural monopoly industries through private capital participation in the investment and management of natural monopoly industries Efficiency and efficiency of industrial distribution. China’s urban tap water industry started the privatization reform in the 1990s, but there is a lack of systematic and quantitative research on the effectiveness of the reform. This paper examines the performance differences of enterprises with different property rights in tap water industry in Guangdong Province from two aspects of static efficiency and dynamic efficiency. The results show that the privatization reform of natural monopoly industries should break the monopoly and promote competition and property rights Only if reform is carried out can we achieve obvious results.
