1978-2017年中国区域农业经济发展差距与结构特征

Structural characteristics and development gap of regional agricultural economy in China from 1978 to 2017

改革开放以来,中国农业经济实现了持续较快的增长,但区域间农业发展不平衡问题仍较为突出。基于1978—2017年31个省区市的农业劳动力投入和经济产出数据,利用泰尔指数从南北方、东中西部2个维度测度中国区域农业经济发展差距及其结构特征。结果表明:从区域间发展差距看,改革开放以来,中国南北方农业经济发展差距不断缩小,东中西部的发展差距是现阶段中国农业经济发展差距的主要来源;从区域内部看,南方地区内部省际农业经济发展差距较大,西部地区内部省际发展差距大于中部和东部地区。

Since the reform and opening up,China s agriculture has achieved rapid growth,but the problem of uncoordinated agricultural development among regions is still outstanding.Based on the panel data of labor input and economic output of the first industry in 31 provinces(autonomous region,municipality)from 1978 to 2017,the Theil index was introduced to measure the regional development gap of agricultural economy and its structural characteristics.It was shown that,from the perspective of regional development gaps,the development gap in agricultural economy between the north and south of China has been shrinking since the reform and opening up.The development gap within the east,central and west is the main source of the development gap in China s agricultural economy currently.The inter-provincial development gap in agricultural economy in the south is larger than that in the north,and the development gap within the west region is larger than that within the central and east regions.
