在缺陷市场条件下,政府边界模糊、社会组织缺乏承接力以及购买程序化不公平等问题的存在,导致当前政府购买公共服务缺乏必要的竞争。本文分析了这些竞争性难题的表现、性质、成因和影响,指出缺陷市场带来的竞争问题要靠完善市场来解决,但政府购买是有限的市场化,有自己的边界,政府更应该注重培育社会力量的承接能力,发挥社会志愿机制对竞争性的促进作用。 Under the imperfect market conditions, the government has ambiguous boundaries, the lack of acceptability of social organizations and the unfairness of purchase procedures. As a result, the government currently lacks the necessary competition to purchase public services. This paper analyzes the performance, nature, causes and effects of these competitive problems. It points out that the competition brought by the defective market depends on improving the market. However, government purchases are limited to marketization and have their own boundaries, and the government should pay more attention to cultivating The ability to undertake social forces, giving play to the role of social voluntary mechanisms in promoting competition.
