地铁对沿线写字楼租金影响的空间效应分析——以西安地铁2号线为例

Analysis on Space Impact of Metro on Office Rent——Taking Xi 'an Metro Line 2 as an Example

以西安地铁2号线沿线的出租型写字楼为研究对象,在综合考虑影响写字楼租金的各种内外部因素的基础上,运用BP神经网络模型定量分析西安地铁2号线对沿线写字楼租金的空间效应。结果表明:西安地铁2号线对沿线出租型写字楼的租金有显著的影响,在距离地铁口800米内的平均影响力为10.5%,在100到300米内,写字楼租金随着距离的增加逐渐增加,在300到800米之间,则随着距离的增加逐渐降低,且降幅越来越大。最后就优化土地资源利用提出建议,以期为地铁周边土地合理利用提供决策支持,为开发商科学选择写字楼区位提供参考。

With the rental offices along Xi＇an Metro Line 2 as the research object, considered various kinds of inter- nal and external factors that impact on office rents, quantitatively analyzed the spatial effect caused by Xi＇an Metro Line 2 on the nearby office rents by BP neural network model. The results show that Metro Line 2 has significant in-fluence on the rental offices alongside. The average influence index 800 meters away from the subway entrance is 10.5%. Within the 100 to 300 meters, the rent becomes higher when the distance got farther. On the other side, be-tween 300 to 800 meters, the rent would become lower as it got farther, and the decline extent would be increasingly sharper. Finally, it proposes some practical suggestions, which can provide some decision supports for the rational use of land surrounding the subway and some references for developers to locate offices.
