我国渔业燃油补贴对渔业资源的影响分析——以山东省日照市为例

The impact of fishery fuel subsidy policy on fishery resources: based on double-log linear panel model

如今越来越多的国家和国际组织开始专注渔业补贴对渔业资源可持续利用的影响。2006年以来,我国渔业燃油补贴的实施有效缓解了柴油价格上涨所带来的渔业生产压力,但有学者认为燃油补贴可能会引发过度捕捞。为了研究渔业燃油补贴对渔业资源的影响,本文首先利用Gordon-Schaefer模型进行了理论分析,然后基于柯布-道格拉斯生产函数的基础上,建立了双对数线性模型。对2007-2013年山东省日照市的渔业燃油补贴等面板数据,分别采用单向固定效应和双向固定效应的回归方法,并使用以区县为聚类变量的聚类稳健标准差,对渔业燃油补贴与捕捞总量之间的数量关系进行了实证分析。结果表明,渔业燃油补贴对捕捞总量有显著的正向影响,其弹性系数为0.561。

Since the fishery fuel subsidy policy was carried out in 2006, it has effectively relieved the contradiction between diesel prices rise and the fishery production, meanwhile, the number of fishing vessels is increasing. But some people believe that the fishery fuel subsidy could lead to overfishing and then lead to the gradual degradation of the fishery resources and the deterioration of the ecological environment. In view of this, this paper first analyses the changes in Gordon-Schaefer model with the fishery fuel subsidy to explain the impact on fishery resources, and secondly establish double Log-linear models based on Cobb-Douglas production function. Then we use the fishery fuel subsidies panel data of Rizhao from 2007 to 2013 to empirical analysis the effects of fishery fuel subsidy on fishery resources with one-way fixed effect and two-way fixed effect model. Results show that fishery fuel subsidy was significantly and positively correlated with the output of fishing and the elasticity coefficient is 0.561. It means fishing production will increase by 0.561% when fishery fuel subsidies increase by 1%. Finally, we have made some suggestions about the fishery fuel subsidy policy. We can adjustment fishery subsidies coefficient for calculating oil and strengthen the publicity and guidance of fishery fuel subsidy policy to eliminating misunderstanding.
