城市规划在可持续中国城市发展中的作用

Abstract

可持续发展理论讨论的基本共识集中在经济效率、社会公正、环境可持续,以及为达到前述三目标的制度安排。城市规划究竟能够在市场经济引导下的城市可持续发展中起什么作用？城市规划作为制度可以在城市土地开发竞争中起降低交易成本的功能,从而促进城市的经济效益;城市空间规划能够与生态技术结合为创建生态城市作出有效的贡献;但是规划本身不具备机制能够积极地改善社会公正。除此之外,规划完全有能力在睿智发展和紧凑城市的两个领域推动中国可持续城市发展。

Sustainable development focuses on economic efficiency,social equity,ecological environment,as well as institutional arrangement for achieving those three objectives.How can urban planning help to achieve sustainable cities under the market economy? Urban planning as an institution can reduce transaction costs in the game of competitive land development,thereby enhancing urban economies.Land use planning can probably incorporate ecological technologies(such as clean energy and green buildings) and develop eco-cities.However,urban planning does not have an effective mechanism to deal with social inequality positively.Smart growth and compact city should be the two paradigms for China's urban sustainability that urban planning can make a significant contribution.
