摘要:传统国民经济核算体系忽略了对自然资源的核算,不能全面反映区域经济发展的真实水平。在2010—2018年江西省水资源水质实物量核算的基础上,利用恢复成本法核算其价值量。结果表明:2010—2018年江西省水资源Ⅰ类水质占比及水量日趋减少,水质等级降低后主要以Ⅱ类和Ⅲ类水为主;除Ⅱ类水外,其他类型的水质价值量总体呈下降趋势。2010—2015年江西省以水资源折旧调整的EDP比GDP平均下降了5.7%,说明以GDP为核心的现行国民经济核算体系指标过高估计了江西省的经济发展水平。2011—2014年江西省水资源价值平均损失为当年GDP总量的4.5%以上,说明“十二五”期间江西省经济增长是以消耗水资源换取的。2015年后江西省由水资源价值损失所取得的GDP增长率大幅下降,水资源水质价值量不断上升,说明江西省在GDP增长的同时存在水资源的正外部性。根据以上分析结果,有针对性地提出了江西省水资源保护的相关政策建议。关键词:恢复成本法;水资源水质价值核算;江西省Abstract:Traditionalnationaleconomicaccountingignoresnaturalresourcesaccounting,whichcannotfullyreflectthereallevelofregionaleconomicdevelopment.BasedonthecalculationofphysicalquantityofwaterqualityforJiangxiProvincefrom2010to2018,restorationcostmethodwasusedtoaccountingthevaluequantityforwaterquality.TheresultsshowedthattheproportionanditsamountofClassIwaterquantitywasdecreasingfrom2010to2018,andafterthewaterqualitygradewasreduced,wasdominatedbyClassIIandClassIIIwaterinJiangxiProvince;thevaluequantityforotherclassshowedadecreasedtrendduringthewholecourse,exceptforClassIIwater.From2010to2015,adjustedEDPbywaterresourcedepreciationdecreasedby5.7%onaveragethanGDPinJiangxiProvince,indicatingthattoGDPasthecoreofthecurrentnationaleconomicaccountingsystemindicatorsoverestimatedthelevelofeconomicdevelopmentofJiangxiProvince.From2011to2014,thevaluelossofwaterresourcesinJiangxiProvincewasmorethan4.5%oftotalGDPofthatyear,showingthattheeconomicgrowthofJiangxiProvinceduringthe12thFive-yearPlanPeriodwasinexchangeforthedestructionofwaterresources.Since2015,theGDPgrowthrategainedfromthevaluelossofwaterresourceinJiangxiProvincehaddecreasedsignificantly,andthevalueofwaterqualit...
