基于SBM－Malmquist模型的云南林业生态效率测算及时空差异性研究肖永茂，龙勤*(西南林业大学经济管理学院，云南昆明650224)摘要运用SBM－Malmquist模型对2011—2020年云南16个州市的林业生态效率进行空间和时间测度。结果表明:云南林业生态效率整体水平较高，呈波动上升趋势，但未达到稳定的最优水平;规模效率是制约云南林业生态效率的关键要素;林业生态效率的静态效率值(TC)呈现出滇东北＞滇中＞滇南＞滇西北的特征;林业生态效率的动态效率值(Mg)大部分时间为低促进水平，林业技术进步效率有待加强;各区域林业生态效率的动态效率波动大，且区域间存在明显差异。最后，提出了促进云南林业生态效率高水平发展的建议。关键词林业生态建设;生态效率测度;SBM－Malmquist模型;云南中图分类号F326．2文献标识码A文章编号0517－6611(2023)07－0142－04doi:10．3969/j．issn．0517－6611．2023．07．033开放科学(资源服务)标识码(OSID):AnalysisonForestryEco-efficiencyinYunnanProvinceBasedonDEA-SBMandMalmquistModelXIAOYong-mao，LONGQin(SchoolofEconomicsandManagement，SouthwestForestryUniversity，Kunming，Yunnan650224)AbstractBasedonSBM-Malmquistmodel，calculatestheforestryecologicalefficiencyvalueanddynamicindexof16prefecturesandcitiesinYunnanfrom2011to2020，andanalyzesthespace-timechangesofforestryecologicalefficiencyinYunnan．TheresultsshowedthattheoveralllevelofforestryecologicalefficiencyinYunnanwashigh，showingafluctuatingupwardtrend，butdidnotreachthestableoptimallevel;scaleefficiencyisthekeyfactorthatrestrictstheecologicalefficiencyofYunnanforestry．ThestaticefficiencyofforestryecologicalefficiencyshowedthecharacteristicsofNortheastYunnan＞MiddleYunnan＞SouthYunnan＞NorthwestYunnan．Thedynamicefficiencyvalueofforestryeco-logicalefficiencyislowinmostofthetime，andtheefficiencyofforestrytechnologicalprogressneedstobestrengthened．Thedynamicefficien-cyofforestryecologicalefficiencyfluctuatesgreatlyineachregion，andthereareobviousdifferencesamongregions．Finally，somesuggestionsaregiventopromotethehighleveldevelopmentofforestryecologicalefficiencyinYunnan．KeywordsForestryecologicalconstruction;Eco-efficiencymeasurement;SBM-Malmquistmodel...
