摘要
从空间视角研究鸡蛋价格波动的空间分布对稳定鸡蛋市场,协调产业区域均衡发展有重要意义。文章基于我国19个省份2011年8月至2018年6月鸡蛋交易价格的月度数据,构建经济距离矩阵来弥补地理权重矩阵的不足,运用空间模型对鸡蛋价格的空间相关性进行验证。结果表明:中国鸡蛋价格集聚效应显著,且以"H-H"和"L-L"型集聚为主;从时间上来看,邻接省域鸡蛋价格同步性明显,从空间上看,鸡蛋价格波动存在明显跨区域的空间溢出效应;产业集聚对鸡蛋价格波动的影响较大,两者之间表现出"U型"关系。
Studying the spatial distribution of egg price fluctuation from the perspective of space is of great significance for stabilizing the egg market and coordinating the balanced development of industrial regions. Based on the monthly data of egg transaction prices in 19 provinces from August 2011 to June 2018, this paper constructs an economic distance matrix to make up for the deficiency of geographical weight matrix, and also uses spatial model to verify the spatial correlation of egg price. Results show that the agglomeration effect of egg price in China is significant, with "H-H" and "L-L" agglomeration dominated;from the perspective of time, the egg price in the neighboring province is obviously synchronous, and from the perspective of space, the egg price fluctuation has obvious spatial spillover effect across regions. Industrial agglomeration has a great influence on egg price fluctuation, and there is a U-shaped relationship between the two.
