本文基于浙江省1990—2011年69个县和2004—2006年1 215个乡镇的面板数据,利用实际交通时间的倒数设定空间权重矩阵,通过空间Durbin模型考察经济集聚对农民收入的直接影响和空间溢出效应。结果表明:经济集聚对农民收入有显著的直接提升作用,而其他区域的经济集聚与经济距离共同作用,产生了对农民收入正向的空间溢出效应。本文发现,传统上未考虑空间溢出效应的模型设定,高估了当地经济集聚对农民收入的影响,而低估了经济集聚对农民收入的总体效应。
This paper studies the direct and spillover effect of economic agglomeration on farmer's income with the spatial Durbin model. The results show that economic agglomera- tion has a significant positive direct effect on farmer's income. Economic agglomeration from other areas, together with the economic distance, has a significant positive spatial spillover effect on farmers' income. The total effect of economic agglomeration is also positive and sig- nificant. Compared to the spatial Durbin model, the traditional model not considering the spatial spillover effect overestimates the direct effect of economic agglomeration on local farmers' income but underestimates the total effect
