基于时滞网络DEA的我国省域林业系统资源优化配置研究基于时滞网络DEA的我国省域林业系统资源优化配置研究

摘要：

林业作为我国国民经济和社会发展的重要产业之一，早已成为以林业资源为基础的多种产业和社会事业的支撑。由于省域林业系统资源配置存在着很多的非线性和时滞特性，使得优化配置变得十分复杂和困难。本文基于时滞网络DEA（Dataenvelopmentanalysis）模型，以我国典型省域林业系统为例，从经济、社会、生态等多个方面出发，探究如何实现省域林业系统资源的优化配置。首先提出了时滞网络DEA模型的基本原理，在此基础上对模型进行了改进，建立了基于量化和非量化指标的林业系统资源配置模型。通过模型求解，得到了典型省域林业系统的资源配置效率和效益指标，分析了优化配置后的影响和实质意义。最后，进一步探讨了优化配置实践中面临的挑战和研究方向，为推动省域林业系统的可持续发展提供了参考和借鉴。

IndicatorsofProvincialForestrySystem

Theindicatorsoftheprovincialforestrysystemaredeterminedbasedonthecharacteristicsandgoalsoftheforestryindustry.Ingeneral,theindicatorscanbedividedintothreecategories:economicbenefits,ecologicalbenefits,andsocialbenefits.

EconomicBenefits

Economicbenefitsrefertothecontributionoftheforestryindustrytoeconomicdevelopment.Themainindicatorsofeconomicbenefitsincludetheoutputvalueofforestryindustry,theincomeofforestryworkers,andtheprofitsofforestryenterprises.

EcologicalBenefits

Ecologicalbenefitsrefertothecontributionoftheforestryindustrytotheprotectionandimprovementoftheecologicalenvironment.Themainindicatorsofecologicalbenefitsincludeforestcoveragerate,carbonsequestrationcapacity,andbiodiversity.

SocialBenefits

Socialbenefitsrefertothecontributionoftheforestryindustrytosocialdevelopment.Themainindicatorsofsocialbenefitsincludeemploymentopportunitiescreatedbytheforestryindustry,theimprovementofinfrastructureinforestryareas,andthepromotionofruraldevelopment.
