海西经济区城镇化效率与经济发展水平时空耦合关系研究

Spatio-temporal Coupling Relationship Between Urbanization Efficiency and Economic Development Level in West-straits Economic Zone

【目的/意义】经济发展与城镇化之间的关系一直是经济研究的热点话题,探究两者之间的关系有助于推进我国城市与社会的可持续发展。【方法/过程】基于海峡西岸经济区2011—2017年的数据,利用MaxDEA 8.0软件构建产出有界的SBM—DEA窗口模型计算城镇化效率,利用熵值法计算经济发展水平,在这基础上进一步分析二者耦合协调性的动态关系。【结果/结论】海西经济区城镇化效率、经济发展水平及其耦合度均有向好的趋势。在研究期间内,城镇化效率平均值由0.851上升至0.860,平均经济发展水平由0.218上升至0.388,耦合度由0.772上升至0.906。可以看出,经济发展水平对耦合度呈现倒“U”型分布关系,经济发展水平与城镇化效率也存在倒“U”型分布关系。

【Objective/Meaning】The relationship between economic development and urbanization has always been a hot topic in economic research.Exploring the relationship between the two is conducive to promoting the sustainable development of cities and society in C hina.【Methods/Procedures】Based on the data of the west-straits economic zone from 2011 to 2017,MaxDEA 8.0 software was used to build the SBM—DEA window model with bounded output to calculate the urbanization efficiency,and the entropy method was used to calculate the economic development level.On this basis,the dynamic relationship of coupling coordination between the two was further analyzed.【Results/Conclusions】The urbanization efficiency,economic development level of the west-straits economic zone and their coupling degree all had positive trend.During the research period,the average urbanization efficiency increased from 0.851 to 0.860,the average economic development level increased from 0.218 to 0.388,and the coupling degree increased from 0.772 to 0.906.It could be seen that the economic development level presented an inverted U shape distribution relation to the coupling degree*and there was also an inverted U shape distribution relation between the economic development level and urbanization efficiency.
