| 目的 掌握糖料生产布局规律，引导并支持糖料生产向优势主产区转移，将能够在一定程度上提高中国糖料的市场竞争力。方法 利用1980—2015年13个省（区）的面板数据，采用描述性统计和固定效应模型，文章重点对中国糖料生产布局变动、区域比较优势及其影响因素进行了分析。结果 改革开放后中国糖料品种逐步向甘蔗集中；甘蔗生产逐渐向华南的广西和西南的云南集中；甜菜生产逐步向西北的新疆和内蒙古聚集。从区域比较优势看，现行中国糖料生产布局是符合生产规律的。此外，研究还发现比较效益、农户粮食安全供给水平、有效灌溉面积和农业机械化水平对中国甘蔗生产布局具有显著的正向影响；有效灌溉面积、受灾程度和临时收储政策对中国甜菜生产布局具有正向促进作用。结论 建议从做好全国糖料生产区域规划、精准给予糖料生产支持政策及提高政策支持成效三方面下功夫。 |

| Abstract: |
| Using panel data from 13 provinces between 1980 and 2015, and descriptive statistics method and fixed-effect models, this paper focused on the analysis of changes in China's sugar production layout, regional comparative advantages, and influencing factors. Results showed: The layout of sugar varieties in China was gradually concentrated to sugarcane after the reform and opening up. In the regional distribution, China's sugar cane production was gradually concentrated to the south and southwest regions, especially in Guangxi and Yunnan province; sugar beet production was gradually concentrated to the northwest area, especially in Xinjiang and Inner Mongolia provinces. From the perspective of regional comparative advantage, China's sugar production layout was analyzed in depth and the regularity of production changes in the distribution of sugar was confirmed. In addition, this paper also found that comparative profit, farmer food security supply level, the effective irrigation area, and the level of agricultural mechanization had significant positive effects on the distribution of sugar cane across China. Moreover, effective irrigation area, the degree of disaster, and temporary purchasing and storage policy had positive effects on the change of Chinese sugar beet production. It is recommended that sugar production should be done well from the aspects of the national sugar production regional planning, the accurate provision of sugar production support and the improvement of policy support. |
