摘要
通过构建三江平原垦区基础设施和城镇化评价指标体系,运用主成分分析法,建立垦区基础设施评价函数和城镇化评价函数,分析了垦区的基础设施和城镇化发展现状。结果显示,垦区的基础设施水平和城镇化水平自2000年起呈现波动上升趋势,并且二者的协调性不断提高,最终围绕平衡状态上下波动。为检验垦区基础设施建设对城镇化的影响,将研究区域划分为基础设施建设超前型和滞后型,并对两组样本的基础设施水平和城镇化水平进行回归分析,发现垦区的基础设施对城镇化有较大的推动作用,并且基础设施超前型区域的推动效果更强。最后从基础设施建设的角度提出促进三江平原垦区城镇化发展的具体对策。
Reclamation towns have formed a special urban settlement pattern. With the development of economy and society, urbanization is an inevitable trend and urgent requirement in reclamation towns. There are many factors that affect the urbanization process. In order to measure the effects of infrastructure on urbanization in the reclamation area; the article selected a reclamation area in Sanjiang Plain as the study object. Firstly, the article constructed infrastructure and urbanization evaluation index systems. Then infrastructure evaluation function and urbanization evaluation function were established by principal component analysis. By analysis of the present situations of infrastructure and urbanization, we found that the level of infrastructure and urbanization grew steadily; the coordination between infrastructure and urbanization improved continuously. Thirdly, we divided the area into advanced type and lagged type by subtracting the infrastructure level and urbanization level, and we conducted regression analysis to examine the relationships between infrastructure level and urbanization level of both types. The model built in this article can explain more than 90% of the variation of urbanization at more than 95% confidence level. The result reveals that infrastructure affects the urbanization greatly, especially, when the infrastructure level is higher than urbanization level. Finally, we put forward the suggestion for the improvement of the quality of urbanization from infrastructure aspect in the reclamation area in Sanjiang Plain.
