Abstract

This study analyses the technical efficiency of the forestry sector in Europe which comprises 40 countries. The novelty of this study is the stochasticity of the data and the existence of contextual variables in the two-stage production process of the forest sector. We first developed a two-stage chance-constrained data envelopment analysis model in which the forestry and exploitation stages occur at country-specific levels within the European forest production sector. It was found that the forest management stage is generally more efficient than the exploitation stage and total production at the country-specific level. Contextual variables have a significant impact on efficiency scores, which means that efficiency calculations in the subsequent stage need to be adjusted to take these influences into account. By mitigating these contextual effects, the study improved technical efficiency scores, highlighting top performers like the Russian Federation (DMU31 in North zone), Switzerland (DMU37 in Central-West zone), and Iceland (DMU16 in North zone) with TE scores of 1.0322, 1.0209, and 1.0198 respectively, while also identifying areas for enhancement in countries such as Turkey (DMU38 in South-East zone), Slovakia (DMU33 in Central-East zone), and Romania (DMU30 in Central-East zone) which fall into the lowest three ranks based on their performance with TE scores of 0.5583, 0.5058, and 0.4482 respectively. An important conclusion is that these findings are crucial for policymakers and stakeholders in Europe when developing strategies to improve efficiency and sustainability in the forest sector.

探索欧洲林业部门的技术效率:两阶段机会约束数据包络分析
本研究分析了由40个国家组成的欧洲林业部门的技术效率。本研究的新颖之处在于数据的随机性和森林部门两阶段生产过程中上下文变量的存在。我们首先开发了一个两阶段的机会约束数据包络分析模型,其中林业和开发阶段发生在欧洲森林生产部门的具体国家层面。研究发现,在具体国家一级,森林管理阶段一般比开发阶段和总产量更有效。上下文变量对效率得分有显著影响,这意味着后续阶段的效率计算需要进行调整,以考虑这些影响。通过减轻这些背景影响,该研究提高了技术效率得分,突出了俄罗斯联邦(北部地区DMU31)、瑞士(中西部地区DMU37)和冰岛(北部地区DMU16)等表现优异的国家,其TE得分分别为1.0322、1.0209和1.0198,同时也确定了土耳其(东南部地区DMU38)、斯洛伐克(中东部地区DMU33)等国家需要提高的领域。罗马尼亚(DMU30在中东部地区)的TE得分分别为0.5583、0.5058和0.4482,处于表现最低的三个等级。一个重要的结论是,这些发现对于欧洲的决策者和利益相关者制定提高森林部门效率和可持续性的战略至关重要。

期刊介绍: Forest Policy and Economics is a leading scientific journal that publishes peer-reviewed policy and economics research relating to forests, forested landscapes, forest-related industries, and other forest-relevant land uses. It also welcomes contributions from other social sciences and humanities perspectives that make clear theoretical, conceptual and methodological contributions to the existing state-of-the-art literature on forests and related land use systems. These disciplines include, but are not limited to, sociology, anthropology, human geography, history, jurisprudence, planning, development studies, and psychology research on forests. Forest Policy and Economics is global in scope and publishes multiple article types of high scientific standard. Acceptance for publication is subject to a double-blind peer-review process.
