中国建设用地利用效率的空间关联及影响研究

Study on Spatial Correlation and Effect of Utilization Efficiency of Construction Land in China

利用社会网络分析法和QAP方法,测度中国31个省份城市建设用地利用效率的空间关联特征及其影响因素。结果表明:建设用地利用效率的网络密度不断提高,网络结构较为稳定,联系较为密切;东部沿海地区对建设用地利用效率关联及溢出关系具有较强的影响;板块间具有明显的梯度效应,环渤海地区属于双向溢出板块,东部沿海地区属于主受益板块,东北及西部地区属于净溢出板块,中部地区属于经纪人板块;办公楼价格、地均财政支出、单位利用外资差异等因素对建设用地利用效率关联具有显著影响。

Spatial correlation and influencing factors of utilization efficiency of urban construction land in 31 provinces of China were measured based on social network analysis and QAP.The results show that network density of utilization efficiency of construction land is continuously increasing,and the network structure is relatively stable and closely related;the eastern coastal areas have a strong influence on the relation between correlation and overflow of utilization efficiency of construction land;there is an obvious gradient effect of block,bohai rim is bilateral overflow block,the eastern coastal areas belongs to the main beneficiary block,northeast and western areas belong to net overflow block;the factors such as the price of office buildings,fiscal expenditure of land per square kilometer,and the difference of using foreign capital of organization have a significant influence on correlation utilization efficiency of construction land.
