“坚持绿色发展理念，打造生态宜居城市建设”，景区的建设和管理与城市生态环境的优化有密切联系，是城市环境的重要组成，更是为市民提供休憩、娱乐、健身的公共空间，是改善和提高市民生活环境和生活质量的公共产品，是城市建设不可或缺的。随着中国经济的快速发展，城市的发展迎来了春天，景区的发展也随之进入了快车道。现代化建设的深入也使得景区获得了大的发展，无论从数量上还是规模上都有了大的增长，品质也不断得到提升。但囿于发展的时间短，对景区的管理运营上仍较为欠缺，出现功能弱化，设施更新不及时等问题导致社会、游客质疑声音越来越大。不仅如此，景区在经营管理过程中选择了不适宜的模式，不仅对生态资源不能起到保护作用，更不用提促进景区发展了。因此，寻求科学合理的景区管理运营模式，不仅可以解决景区的资源保护问题，也可以解决景区的可持续发展问题，这是一项非常重要的课题。 本文以门城湖景区为例，探究其公共产品供给效率。门城湖为免费的开放式景区，随着连年的运行和管理，政府和社会的不满和质疑越来越严重，供给效率明显下降。为提高门城湖景区公共产品的供给效率，本文通过介绍研究背景、分析国内外相关研究成果，最终确定了研究目标、研究意义和研究方法。 以“公共产品”为理论基础，通过对背景资料的解读，结合景区概况、产品特性、组织情况和投入构成，结合国内外研究成果，探讨了公共产品、供给效率和景区公共产品供给效率等理论的研究成果和研究现状，为改善门城湖景区产品及供给现状提供理论支持。 其次，结合理论与实际，分别对门城湖景区投入和产出两方面进行阐述，确切地找出解决问题的切入点。通过分析，门城湖景区投入由政府全部提供，其投入仅满足景区的刚需，提高或降低门城湖景区的投入都无法作为提高效率的有效手段。因此，需要以提高景区的产出作为解决门城湖景区公共产品供给效率问题的突破口。社会、游客作为景区的消费者、使用者和受益者，其评价最真实的反映了景区的产出情况。通过模糊综合分析法反映出门城湖景区的公共产品产出评价并不高，亟需提高。 最后，根据门城湖景区的公共产品产出评价结果，分析影响其供给效率的原因并提出有助于门城湖景区长期发展的方法与建议，也为其他景区的管理提供了新思想。

“Persist in the concept of green development and build ecological livable cities”, while scenic area construction and management has close relation with optimization of ecological environment in cities, which is the important component of urban environment, provides public spaces for citizens to have a rest, entertain themselves and have exercise, is the public product to improve life environment and life quality of citizens and inevitable in urban construction. With rapid development of China’s economy, urban development has ushered in a spring and scenic area development has also become rapid accordingly. Increasing modernization construction has also allowed scenic areas to obtain a large development in quantity and scale as well as quality. But owing to short development time, scenic area operation and management are still insufficient, involving the problems of weakened functions and untimely facility updating, which causes doubts of the citizens and tourists. Unsuitable operation and management mode of scenic areas will not only do harm to ecological resources but also hinder the development of scenic areas. Therefore, exploring scientific and reasonable scenic area operation and management mode can not only solve the problem of resource protection in scenic areas but also can realize sustainable development, which is a very important research topic. This paper takes Mencheng Lake scenic area as an example to explore the supply efficiency of public products. Mencheng Lake is a free and open scenic area, but it has aroused increasing doubts and dissatisfaction from the government and the public owing to its poor operation and management, therefore, the supply efficiency of public products has declined gradually. In order to improve supply efficiency of public products in Mencheng Lake, this paper finally determines the research objective, research significance and research method through analyzing the research background and related domestic and overseas research achievements. Firstly, this paper takes “public products” as theoretical foundation, analyzes related background materials, bases on the scenic area profile, product characteristics, organizational situation and investment composition and combines with the domestic and overseas research achievements to explore the research achievements involving public product, product product supply in scenic area and supply efficiency as well as the current research situation thus to provide theoretical support for public product improvement in Mencheng Lake and the current supply situation. Secondly, this research combines theory with practices to expound the investment and output of Mencheng Lake scenic area respectively, and finds out entry points for problem-solving practically. It can be seen based on analysis that Mencheng Lake is supported by the government for meeting with its rigid demands, therefore, increasing or reducing investment in Mencheng Lake can not be taken as effective means to improve efficiency. Therefore, enhancing output of scenic area can be a break-through for improve supply efficiency of public products in Mencheng Lake. The public and tourists are the consumers, users and beneficial owners of the scenic area, therefore, their evaluations can truly reflect the output situation of the scenic area. The evaluation on public product output of Mencheng Lake based on fuzzy comprehensive analysis method is not high, which should be enhanced urgently. Finally, this paper bases on the evaluation result of public product output in Mencheng Lake to analyze the reasons for influencing supply efficiency and propose effective method and management mode for long-term development of Mencheng Lake scenic area, which also provides new idea for management of other scenic areas.
