London Plan Business Improvement Districts

A Business Improvement District (BID) is a defined area within which local businesses are required to pay an additional levy. The collected tax will be invested locally to fund projects within the district's boundaries. The BID is often funded primarily through the levy but can also draw on other public and private funding streams. There are currently 70 London BIDs with new ones being developed every year.

Note: The dataset was created by the GLA's GIS team through digitisation of maps published by the BID creators. These original mapsvary in quality and scales of resolution, as a result the GLA cannot guarantee the exact boundary locations.

There is an inconsistency between the number of BID polygons and number of BIDs, this is due to some BID polygons having multiple BID types e.g. Town Centre, Property and Industrial.

商业改善区（Business Improvement District，简称BID）系指特定区域内，当地企业需缴纳额外税费的一种组织形式。所征收的税费将用于资助该区域范围内的各项建设项目。商业改善区通常主要通过征收税费获得资金支持，但也可能利用其他公共或私人资金来源。目前，伦敦地区共有70个商业改善区，且每年均有新的商业改善区正在开发中。

备注：该数据集由大伦敦管理局（Greater London Authority，简称GLA）的地理信息系统团队通过数字化BID创建者发布的地图所构建。这些原始地图的质量和分辨率尺度各异，因此大伦敦管理局无法保证边界位置的精确性。

BID多边形数量与BID数量之间存在不一致性，这是由于某些BID多边形包含多种BID类型，例如市中心、物业和工业区等。
