Spatio-Temporal Analysis of Game Harvests in Sweden
利用动态空间面板数据模型，分析了人类狩猎和食肉动物捕食压力对瑞典有蹄类动物狩猎价值的影响，发现空间效应显著改变了猞猁对狍子狩猎价值的影响，并证实了通过增加狩猎减少野猪种群的政策效果。
Abstract The benefits and costs of wildlife are contingent on the spatial overlap of animal populations with economic and recreational human activities. By using a production function approach with dynamic spatial panel data models, we analyze the effects of human hunting and carnivore predation pressure on the value of ungulate game harvests. The results show evidence of dynamic spatial dependence in the harvests of roe deer and wild boar, but not in those of moose, which is likely explained by the presence of harvesting quotas for the latter. Results suggest the impact of lynx on roe deer harvesting values is reduced by 75% when spatial effects are taken into account. The spatial analysis confirms that policymakers’ aim to reduce wild boar populations through increased hunting has been successful, an effect that was only visible when considering spatial effects.
