企业更替耦合土地发展的城市更新策略——以广州海丝城为例

Urban Renewal Strategies Coupling Enterprise Turnover with Land Development:A Case Study of Haisi City,Guangzhou

基于企业发展与土地整备来推动城市空间有效更新是重要的实践和学术议题。研究基于“问题—对策”的分析框架,以广州海丝城为研究范围,利用ArcGIS和营商主体大数据分析技术,对企业更替状况、行业发展趋势和土地资源配置进行量化分析。研究发现:区域内在业企业年龄结构较年轻,但整体企业生命周期与土地供地期限不匹配;诸如数字经济试验区和开发区等政策型区域的企业迭代趋势显著;总部经济的集聚对区域发展产生多重外溢效应;用地空间破碎和国有集体权属混杂使城市更新的难度加剧。基于企业和土地数据的分析模型,提出基于企业生命周期灵活化土地出让、构建总部生态圈、鼓励土地混合利用和建立差异化土地供应机制等城市临港区域更新策略。

Promoting effective urban spatial renewal through corporate development and land consolidation is an important practice and academic issue.The study,based on a'problem-countermeasure'analytical framework,focuses on Haisi City,employing ArcGIS and big data analysis technology to conduct a detailed quantitative analysis of enterprise turnover situations,industry development trends,and land resource allocation.The findings reveal that:a relatively young corporate age structure stands in the region,yet there is a mismatch between the overall corporate life cycle and the land supply duration.Areas under policies such as digital economy pilot zones and development zones show significant trends in corporate iteration.The agglomeration of headquarters economy generates multiple spillover effects on regional development.Land space fragmentation and the mingling of state-owned and collective ownership complicate urban renewal efforts.Based on the analysis model of corporate and land data,the study proposes urban renewal strategies for the port area,including flexible land lease based on the corporate life cycle,building a headquarters ecosystem,encouraging mixed land use,and establishing a differentiated land supply mechanism.
