山东省与江苏省造纸行业的生态效率比较研究.

Background-- China is Lhc largesL producer and consLimcr of paper and paperboard in Lhc world. WiLh Lhc rapid devclopmcnL of Lhe paper indnsLry, cnvironmcnLal polluLion，especially waLcr consumpLion and waLer polluLion, is also accompanied. ITie fresh waLcr consumpLion acconnLs for abouL 8. 6% 〜8. 9% of Lhe na- Lional indiisLrial waLcr consumpLion, and iLs sewage discharge Lakes up abonL 13% 〜14% of Lhe naLional industrial was Lc waLer. Methods-- Based on Lhe panel daLa of paper indusLry in Shandong Province and Jiangsu Province from 2008 Lo 2017，Lhc sLaLic ecological efficiency of Lhc Lwo provinces is analyzed by using Lhe SBM-DEA model of LinexpccLcd oiiLpiiL, and Lhc driving facLors of LoLal producLiviLy growLh in Lhc paper indiisLi'y arc dynamically analyzed by using Lhc ML index. ITicsc daLa arc mainly from China paper Yearbook (2008-2017). Results-- The rcsulLs show LhaL:①The average sLaLic ecological efficiency of paper indnsLry in Shandong Province and Jiangsu Province arc 0. 91 and 0. 41 in Lhc pasL 10 years，which shows LhaL Lhe ecological efficiency of paper indnsLry in Shandong Province is significanLlv higher Lhan LhaL in Jiangsu Province. In addiLion, paper industries in Shandong have done a good job in boLh reducing cnvironmcnLal polluLion and improving economic onLpiiL. iLs high sLandard of cnvimnmcnLal rcgiilaLion leads Lo high ecological efficiency. Moreover, Lhc improv emenL poLenLial of Lhc five indie aLors of paper indiisLi'ics in Shandong is less Lhan 1%, which indicaLcs LhaL Lhc polluLion emission has been well conLmlled. llowcvcr，Lhc reasons for Lhc low ecological efficiency of paper indiisLi'ics in Jiangsu Province arc noL only Lhc excessive consumpLion of resources and Lhc discharge of pollii- LanLs，bnL also Lhe insufficiency of economic oiiLpnL, among which Lhe excessive discharge of COD and AM is Lhc primary i nil nene ing facLor.② The TFP of paper indnsLries in Shandong Province is obviously higher Lhan LhaL in Jiangsu Province. The gmvvLh of LoLal producLiviLy in Shandong paper indnsLries is due Lo Lhe improv emenL of MLTEC11, and mosL of Lhc paper cnLerpriscs in Shandong Province choose cnvironmcnLally sound Lcchnologv Lo achieve cnvironmcnLal rcgidaLions, and Lhcsc Lechnological innovaLions effeeLively improve Lhe ecological efricicncy of enLerprises. However， Lhe low TFP of paper indnsLries in Jiangsu is due Lo Lhc decline of MLTEC11. In reccnL veal's, some paper enLerprises in soiiLhcrn Jiangsu arc gradually shifLing Lo norLhern Jiangsu. Compared vviLh soiiLhcrn Jiangsu, which has more perfeeL polluLion conLrol faciliLies, Lhc paper indiisLry in JNorLhern Jiangsu is hound Lo form a larger cnvimnmcnLal polluLion load. Conclusions and Discussions-- This paper provides Lhe following Lhree siiggcsLions for Lhe dcvclopmcnL of paper indiisLi'y in Jiangsu Province. FirsLlv, Lhc paper indnsLry in Jiangsu Province should sLrengLhen Lhc supervision of Lhe discharge sLandards of paper-making wasLewaLer in Lhe norLh of Jiangsu Province, and Lhe en- Lcrpriscs should be rcgiilaLed according Lo Lhc rules LhaL fail Lo meeL Lhc discharge sLandards Lo rccLify or shiiL down in Lime. Secondly, Lhc paper indiisLi'y in Jiangsu Province should speed up Lhc pace of indLisLrial res Lr Lie Luring ,achieve scale effeeL and inLernalizc Lhe cosL of polluLion conLrol. And Lhc problem of raw maLerials in papermaking indnsLry should be paid more aLLenLion Lo. FnrLhermorc, Lhe access Lhreshold for enLerprises Lo enLer Lhc paper indnsLry and snpporL merger or rcorganizaLion needs Lo be enlarged. Thirdly，cleaner proclncLion Lechnologv Lo improve Lhe ecological efficiency of paper indiisLi'y should be vigorously promo Led in Jiangsu Province. Papermaking enLerprises need Lo be cncoLiraged Lo conLinnc Lo increase invcsLmcnL in cnvironmcnLal pro Lee Lion, research and devclopmcnL, and innovaLion of cleaner prodhcLion Lcchnologv.
