青岛市工业与农业部门间潜在水权交易规模测算

Estimation of potential transaction scale of water right between industrial and agricultural sectors in Qingdao City

利用山东省17地市2007—2011年工业部门和农业部门的面板数据估计2个部门的生产函数,并利用生产函数的参数估计值测算青岛市农业部门和工业部门之间的潜在水权交易规模。研究结果表明:水资源对2个部门的产出产生了显著影响;水权交易均衡状态下工业部门与农业部门间水资源边际收益差异越小,潜在水权交易规模越大;2007—2011年潜在水权交易规模总体上在逐渐加大。

The production function of the industrial and agricultural sectors is estimated by using their panel data of 17 cities in Shandong Province from 2007 to 2011. The potential transaction scale of water right between the two sectors is measured by means of the estimated parametric values of the production function.The results show that the water resources have significant effect on the production of both the industrial and agricultural sectors. The smaller the marginal revenue difference between the two sectors under water right transaction equilibrium,the larger the potential transaction scale of water right. The potential transaction scale of water right generally increases during the period from 2007 to 2011.
