Land use Controls: The Case of Zoning in the Vancouver Area
研究温哥华都会区三个地点的重新区划与房产价值变化的关系，发现重新区划不一定改变土地用途和价值，且未发现不相容土地使用导致显著负外部性的证据，质疑已开发城区继续使用区划的合理性。
This paper explores the relationship between rezoning and changes in observed property values and the ability of zoning to mitigate externalities. Three separate methodologies are used in three locations in metropolitan Vancouver to examine these issues. Our results imply that rezoning does not necessarily lead to changes in land use and value. Further, no evidence was found to support the assertion that there are significant negative externalities due to incompatible land uses in residential property markets. Based on these results, we feel it is reasonable to question the continued use of zoning in developed areas of urban regions.
