利用1980-2010年29个省份的播种面积数据，计算农业区域专业化系数，发现整体上专业化水平显著且稳定提升，但不同农产品和省份间存在差异。
This paper calculates the regional specialization coefficient of China's 29 provinces and six kinds of main agricultural products from 1980 to 2010 by using panel data of sown area,and analyzes the characteristics and changing trends of agricultural regional specialization degree from views of industry and region.This study's results show that,the regional specialization coefficient of agriculture presents a trend of consistent rapid rising from the calculated result of industrial view and regional view,this indicates that the level of agricultural regional specialization presents a trend of significant and steady improvement on the whole.From the industrial view,within six kinds of agriculture products,except the vegetable,the degree of regional specialization of agricultural production of the other five products expresses a significantly increased trend but a noticeable distinction in this trend.From the regional view,the degree of regional specialization of agricultural production presents a enhancement trend on the whole in various provinces,division of regional specialization make further strengthen.
