【摘要】 在剔除三部门重合地理标志农产品后，基于2010—2018年中国30个省份(因数据缺失，未包括西藏和港澳台地区)的面板数据，构建空间杜宾模型和面板门槛回归模型，实证研究地理标志农产品对城乡收入差距影响的空间溢出效应和非线性影响。研究结果显示，城乡收入差距的空间集聚特征明显，且具有显著的正向空间自相关性；地理标志农产品能够抑制本省域及邻近省域城乡收入差距的扩大；随着经济发展水平的提高、交通基础设施水平的提升，地理标志农产品缩小城乡收入差距的作用逐渐增强。更多还原

【Abstract】 Based on the panel data of 30 provinces(due to the lack of data, the statistical data mentioned here do not include the Tibet Autonomous Region, the Hong Kong Special Administrative Region, the Macao Special Administrative Region and Taiwan Province) in China from 2010 to 2018, the spatial dobbin model and the panel threshold regression model were constructed to empirically study the spatial spillover effect and non-linear effect of geographical indication agricultural products on the urban-rural income gap after removing the overlapping geographical indication agricultural products. The results show that the spatial agglomeration of urban-rural income gap is obvious and has significant positive spatial autocorrelation; geographical indication agricultural products can inhibit the widening income gap between urban and rural areas in this province and neighboring provinces; with the improvement of economic development and transportation infrastructure, the role of geographical indication agricultural products in narrowing the income gap between urban and rural areas has gradually increased.更多还原
