摘要:
生态控制线是生态空间管控的重 要举措之一,也是保护城市生态环境和提升 生态环境质量的有效手段。但是,由于复杂 的产权纠纷和历史遗留问题,它的划定在实 际操作过程中面临着诸多挑战。妥善处理生 态线内已建社区和合理进行社区改造已成 为重要议题。本文以深圳市为例,系统梳理 生态线内社区的特征,并引入交易成本的概 念,分析生态线内社区改造过程中政府、社 区、居民和开发商等利益主体的成本与收 益,指出生态线内社区改造的难点在于交易 成本过高以及收益与成本缺口巨大,并在此 基础上提出一系列针对性的改造策略,以期 更好地推进生态线内社区改造,逐步完成生 态修复工作,更好地实现生态价值与社会经 济价值,并为其他城市提供借鉴和参考。

Abstract:
Ecological control line is a crucial tool for ecological space management. It is also an effective measure for environmental conservation and improvement in urban areas, preventing cities from expanding beyond their pre-set boundaries. China pioneered its ecological control line in Shenzhen in 2005. Since then, seamless integrations of this technique into urban planning has received ever more spotlights. However, ecological control lines are hard to scientifically designate. Mishandling would lead to government-resident disputes. Worse still, property rights and historically unresolved problems further add to complexity of the issue. So, practicing the technique is quite challenging. Thus, proper ways to handle and renovate the built environment of urban communities within ecological control areas has become a focus in academic research. The study applies the concept of transaction cost to the analysis of Shenzhen’s case. Gaming behaviors and policy responses during the transformation of communities within ecological control lines are studied closely. Several features of the communities within ecological control area are summarized, including fragmented spatial structure, complexed social structure, and simplifi ed economic structure. Using the transaction cost theory, our analysis covers holistically costs and benefi ts for community transformation. This is followed by a detailed account of costs and benefi ts for different stakeholders(i.e., government, developers, and residents). The study highlights that excessive transaction costs and pessimistic income prospects contribute to diffi culties of refi ning ecological control lines. Based on this reasoning, the study recommends a reform strategy for urban transformation, environmental recuperation, and maximization of social and environmental welfare. It provides a valuable reference for other cities which implement similar policies.
