论水资源费的超额负担

On the Excess Burden of Water Resource Charge

运用哈伯格三角分析了水资源费超额负担的存在以及计量,阐述了其产生的原因,即商品相对价格变化与替代效应。征收水资源费虽然会造成效率损失,但从用水的眼前利益与长远利益角度看,两害相权取其轻,水资源费又不得不征。文章提出了水资源费的优化征收方法,既保证水资源费的征收,又尽可能避免或减少征费超额负担。

Using the method of Harberger triangle,the article points out the existence and measure of excess burden of water resource charge.Then it analyses the causes of excess burden,that is,the relative price of goods and substitution effect.Although collecting water resource charge will realize in loss of efficiency,it has no alternative choice,due to the benefit,over not executing the charge,which will be gained from the collection and use of the water resource charge in the long run.The article puts forward measures for water resource charge optimization under condition of ensuring the collection of the charge and avoiding increase of excess burden.
