以生态文明先行示范区作为一项准自然实验,利用2006—2019年城市面板数据,建立双重差分模型,考察生态文明先行示范区政策对城市碳排放效率的影响及其机制。研究发现,生态文明先行示范区政策能够显著提高城市碳排放效率,该结论在经过平行趋势检验、安慰剂检验和排除其他政策干扰等一系列稳健性测试后仍然成立。异质性分析结果显示,对于老工业基地城市、非资源型城市、大城市以及行政等级较高城市,生态文明先行示范区政策的增效降碳效果更显著。作用机制检验结果表明,生态文明先行示范区政策主要通过推动产业结构升级和绿色技术创新促进了城市碳排放效率的提高。

通勤问题一直是城市研究的重点。由于普查数据缺少工作地信息,长期以来通勤研究依赖问卷调查,信息和通讯技术的发展为该问题的研究提供了新的数据、思路和方法。利用2014年上海市某两周的手机信令数据,以张江高科技园区、金桥经济技术开发区和陆家嘴金融贸易区为例,对其就业与居住、通勤时空间特征及地铁通勤进行分析。结果表明,张江的职住比最低,内部通勤比例最高,居住与就业靠近,是自我平衡类型;金桥园区内部缺乏居住,是单一生产类型;虽然陆家嘴是就业居住高密度聚集区,但就业者的居住地分布在中心城区,是城市互动类型。最后,分析了区位、轨道交通、规模、产业及园区内外用地六个因素对不同模式就业区形成的影响,并提出了相应规划建议。
