摘要
运用基于DEA的Malmquist指数方法和油菜成本收益数据,笔者对长江流域油菜主产区油菜生产效率的变动轨迹进行了实证分析,并指出油菜生产效率分布及其影响因素的差异。结果表明:影响长江流域油菜全要素生产率的主要因素是技术进步,深入推进技术进步、提高技术效率及技术管理水平对油菜的指导作用将成为未来该区域油菜发展的新动力。而具体到每个省(市),油菜未来可持续性生产发展的侧重点各有差异。
Based on the Malrnquist index method of DEA and oilseed rape cost-benefit data, the authors analyzed the changes of oilseed rape production efficiency in the main producing areas of Yangtze River Basin, and clarified the distribution of oilseed rape production efficiency and its influencing faetors. The results showed that teehnology progress was the key faetor that affeeted the total faetor productivity of oilseed rape in Yangtze River Basin, the guiding role of technology advaneement, improvement of technieal efficiency and technical management eould become the new power of oilseed rape development. While, the focus of future sustainable development of oilseed rape produetion varied aeeording to local eonditions.
