| 中文摘要: |
| 改革开放以来，我国种植业的空间布局发生了深刻变化。空间布局的演变是趋于专业化还
是分散化，直接影响农业比较优势的发挥。文章选取了12 种主要农作物，以1978—2009 年的省级面板
数据对我国种植业区域专业化进行了实证研究，结果表明，第一，自1978 年以来，全国平均种植业区域
专业化指数呈先降后升的明显趋势，个别年份出现波动，可能与当时的政策或经济环境有关; 第二，各地
种植业区域专业化指数及其变化趋势存在较大差异，农产品结构单一和经济较发达的地区往往专业化
指数较高，而且大都呈上升趋势，而传统农业大省的专业化指数一般较低，且大都呈下降趋势。 |

| The spatial distribution of China's crop production experienced great changes since 1978． Whether this distribution
tends to specialization or decentralization directly influences the effect of agriculture comparative advantage． In this paper，
authors analyze the regional specialization of China's crop production by using a provincial panel data including 12 different
crops during the period from 1978 to 2009． The results indicate that，firstly，the national average index of regional
specialization rose at beginning and then declined，and its fluctuation in different years may be related with the temporal
policy and economic environment． Secondly，there are big differences within regional specialization indices as well as their
variation trends in different regions． High indices belong to the areas with developed economy or single agricultural products
structure and mostly show an ascending trend． While specialization indices of traditional agricultural provinces are generally
low and tend to descend． |
