经济集聚对上市企业绿色创新的影响研究张万里,杨斯悦(西北工业大学公共政策与管理学院,陕西西安710072)摘要:文章基于要素禀赋理论对中国地级市和所有工业行业进行要素密集度分类,选取2010—2019年中国上市公司数据衡量分地区分行业产业多样化和专业化指标,通过PSTR模型研究引入中介变量研发投入后,研究分地区分行业产业多样化和专业化对上市公司绿色创新产出的非线性影响,并得到如下结论:产业多样化随着研发投入的变化对企业绿色创新产出的影响为非线性的;当研发投入不断变化时,产业专业化对企业绿色创新产出的作用也为非线性的;不同要素密集度地区下不同要素密集度行业产业多样化和专业化随着企业研发投入的变化对绿色创新产出的影响不同,部分地区行业的影响为负,继续在当地发展该行业不利于企业绿色创新;研发投入过高或过低,也会影响产业集聚对企业绿色创新产出的正向作用,企业应适当进行研发投入。关键词:专业化;多样化;要素密集度;企业绿色创新中图分类号:F270文献标识码:A文章编号:1004-292X(2023)02-0067-06ResearchontheImpactofEconomicAgglomerationonGreenInnovationofListedEnterprisesZHANGWan-li,YANGSi-yue(PublicPolicyandAdministration,NorthwesternPolytechnicalUniversity,Xi'anShaanxi710072,China)Abstract:Basedonfactorendowmenttheory,thispaperclassifiesChineseprefecture-levelcitiesandallmanufacture-industries.ThepaperusesthedataofChineselistedfirmsfrom2010to2019tomeasureindustrialdiversificationandspecializationindifferentregionsandsectors.ItalsousesPSTRmodeltostudythenon-linearrelationshipofindustrialagglomerationandgreeninnovationoutput.Thefollowingconclusionsaredrawn:Theimpactofindustrialdiversificationonenterprisegreeninnovationoutputisnon-linearwiththechangeofR&Dinput;WhenR&Dinputisconstantlychanging,theroleofindustrialspecializationonenterprisegreeninnovationoutputisalsonon-linear;WiththechangeofenterpriseR&Dinput,theimpactofindustrydiversificationandspecializationongreeninnovationoutputisdiscrepantindifferentfactor-intensiveareaswithdifferentfactor-intensiveindustries.Someareasevenappearnegative.Contin-uingtodeveloptheindustrylocallyisnotconducivetoenterprisegreeninnovation;ToohighortoolowR&Din...
