BCL教师节献礼｜他们竟然将全国网格的多维度城市活力数据都共享了！

已有城市设计对经济活力影响的定量研究多基于一个城市或小部分城市，并不能代表所有城市。龙瀛及CC HUANG通过在286个城市构建1km*1km的地理单元网格，深入分析城市设计（特别是地块尺度）对经济活力的影响，并结合新数据探究城市形态指标的影响。近期，为了让大家更好地理解该研究，并有机会更充分利用研究数据，作者将其研究的数据（中国全国网格尺度的多维度城市活力和影响因子）进行了共享，数据分享在“北京城市实验室”网站上。好奇的你可以通过访问文末链接或点击“阅读原文”获取免费数据源！

我们希望这一资料将促进中国城市活力的相关研究，同时更多的研究与更好的决策将致力于提高城市活力，增加城市魅力。

数据概述：全国范围内1km*1km网格尺度的城市活力及影响因子数据，包括微博密度、房价、POI密度、人口密度、土地混合度、可达性等。

数据格式：ESRI的ArcGIS10.x中，Shape Files格式

Does block size matter? 

The impact of urban design on economic vitality for Chinese cities

Abstract

The influence of urban design on economic vitality has been analyzed by a number of researchers and is also a key focus of many planning/design theories. However, most quantitative studies are based on just one city or a small set of cities, rather than a large number of cities that are representative of an entire country. With the increasing availability of new data, we aim to alleviate this gap by examining the impact of urban design upon economic vitality for the 286 largest cities in China by looking at a grid of geographical units that are 1 km by 1 km. We use these units and a set of new data (emerging big data and new data that reflecting urban developments and human mobility) to look at the impact of urban form indicators, such as intersection density (urban design), level of mixed use, and access to amenities and transportation, on economic vitality represented by activities using social media data. Our results show that these urban design indicators have a significant and positive relationship with levels of economic vitality for cities at every administrative level. The results contribute to a holistic understanding of how to improve economic vitality in cities across China at a detailed level, particularly at a time when China’s economic growth will depend largely on growth of the service sector in urban areas. We think these results can help decision makers, developers, and planners/designers to improv eeconomic vitality in cities across China.
