摘要:

［目的］把握区域农产品质量竞争力不仅是促进区域农产品富有竞争力的积极方法，也是稳步提升农产品质量安全的重要做法。［方法］文章运用生态位态势理论，构建了以区域为评价主体的农产品质量竞争力评价体系，并从两个层面对浙江省各地级市农产品质量竞争力进行研究。在纵向层面上，测算了各地级市农产品质量竞争力生态位宽度，对各地级市农产品质量竞争力状态进行了评价和排序。在横向层面上，测算了各地级市农产品质量竞争力生态位重叠度，对各地级市农产品质量竞争力的合作程度进行了评价与区分。最后整合运用生态位协同、生态位扩充等理论，提出浙江省各地级市提升农产品质量竞争力发展策略。［结果］通过区域农产品质量竞争力生态位宽度研究发现，杭州和宁波的农产品质量竞争力较强，其生态位宽度分别为0103 6和0103 2，而丽水和舟山农产品质量竞争力相对居后，其生态位宽度分别为0079 0和0075 6； 通过区域农产品质量竞争力生态位重叠度研究发现，可将全省划分为西北平原区域、东南部沿海区域和西南部山地区域等3个区域，各区域内部地级市可通过协同合作提升农产品质量竞争力。［结论］根据各地级市生态位宽度和生态位重叠度的差异，应采取生态位扩充、生态位协同、生态位分离的策略，从而因地制宜提升区域农产品质量竞争力。

Abstract:

To grasp the quality competitiveness of regional agricultural product is not only a positive method to promote the competitiveness of regional agricultural products, but also an important approach to steadily improve the quality and safety of agricultural products. In the paper, the evaluation system of quality competitiveness of agricultural products was constructed by using the ecological niche theory based on the region as the main body of evaluation, and the quality competitiveness of agricultural products in each city of Zhejiang province was studied from two aspects. On the vertical level, the paper calculated the niche breadth of the quality competitiveness of agricultural products in each city, and the quality competitiveness of agricultural products was evaluated and sorted. On the horizontal level, the paper calculated the niche overlap of the quality competitiveness of agricultural products in each city，and the degree of cooperation of quality competitiveness of agricultural products was evaluated and distinguished. Study on the niche breadth through the quality competitiveness of regional agricultural products, the quality competitiveness of agricultural products in Hangzhou and Ningbo was strong, the niche breadth was 0.1036 and 0.1032, while quality competitiveness of agricultural products in Lishui and Zhoushan was relatively low, the niche breadth was 0.0790 and 0.0756; Study on the niche overlap through the quality competitiveness of regional agricultural products can be found, the province was divided into the northwest region, southeastern coastal plain area and southeast coastal areas, each region within the prefecture level city through cooperation can enhance the quality competitiveness of agricultural products. According to the difference of niche breadth and niche overlap degree, the strategy of niche expansion, niche coordination and niche separation should be adopted so as to improve regional agricultural product quality competitiveness.
