Abstract Poland depends on imports for its transportation fuel supply and EC renewable energy policy encourages rapeseed conversion into biodiesel. This paper discusses changes in winter rapeseed production following changes in sugar policy, decreased dependence on potato use as feed and food, and the EU 2007–2009 support program for production of oil seeds as biofuel feedstock. We examine whether farm cost efficiency scores differ across Poland's 16 regions between those growing rapeseed and all other farms using Farm Accounting Data Network (FADN) data. Farms growing rapeseed are more cost efficient in all regions, and while regions with long experience in growing rapeseed still dominate the production, rapeseed production is expanding into new areas. Subsidies offered under the EU support program likely initiated expansion and the expansion continues after the program expired. Less efficient farms can be encouraged to enter rapeseed production through farm outreach services and competitive prices in relation to other crops since the available land permits further expansion of this biodiesel feedstock production.

波兰油菜籽生产和生物柴油生产的扩大和变化的种植模式

摘要 波兰的运输燃料供应依赖进口，欧盟可再生能源政策鼓励将油菜籽转化为生物柴油。本文讨论了随着糖政策变化、减少对马铃薯用作饲料和食品的依赖以及欧盟 2007-2009 年将油籽生产作为生物燃料原料的支持计划，冬季油菜籽生产的变化。我们使用农场会计数据网络 (FADN) 数据检查波兰 16 个地区种植油菜籽的农场和所有其他农场之间的农场成本效率得分是否不同。种植油菜籽的农场在所有地区都更具成本效益，虽然具有长期油菜籽种植经验的地区仍占主导地位，但油菜籽生产正在扩展到新的领域。欧盟支持计划下提供的补贴可能会启动扩张，并且在计划到期后扩张仍在继续。由于可用土地允许进一步扩大这种生物柴油原料的生产，因此可以通过农场外展服务和与其他作物相比具有竞争力的价格鼓励效率较低的农场进入油菜籽生产。
