摘　　要：以产业集群理论为基础,构建林业产业集群水平指标体系,测算林业产业集群指数,探究林业产业集群时空分布特征,并运用固定效应SDM模型分析溢出效应影响因素及不同城市群衰减边界特征。结果表明:中国林业产业集群呈现出局部集中、整体分散,东南沿海-西南-东北集中、中部地区分散的空间格局;集聚明显的城市群包括哈长城市群、山东半岛城市群、东南沿海城市群以及桂东南城市群;中国林业产业集群水平的空间溢出效应明显,林业产业发展对地理区位、资源禀赋、交通条件的依赖性较强,但尚未突破地理边界;各城市群林业产业集群水平的溢出效应衰减边界清晰,不同城市群溢出效应随距离衰减趋势、阈值有所差异。因此,为了整体提高中国林业产业集群水平,应该积极引导培育更多的林业产业核心城市,在城市群内形成双核心或多核心的发展模式,推动城市群格局由链式集群向片式集群发展,最终向区域集群格局转变。⑴Background——Developing forestry industry is an important way to broaden farmers employment channels,promote farmers income increase,and realize rural industry revitalization.Promoting the development of forestry industry clusters is an important development directions of forestry industry.The functions of scale economy,knowledge and technology spillover effect and technological innovation of forestry industry clusters can solve the key problems in the development of forestry industry.Many scholars have analyzed the realization paths,growth models and cluster motivation of industry clusters,and thought that resource endowment,scale economy,labor market,regional economic development level,infrastructure and other factors have an important impact on forestry industry clusters.However,these studies lack empirical support.⑵Methods——In this paper,175 cities in 21 provinces(except Hong Kong,Macao,Taiwan,Xizang,Beijing,Shanghai,Tianjin,Gansu,Qinghai and Inner Mongolia),which are among the top 95%of forestry industry output value in 2022,are taken as the research samples.Based on the theory of forestry industry cluster,this paper firstly constructs the index system to measure the level of forestry industry clusters.Then,using the sample data from 2005 to 2020,the index of forestry industry clusters is calculated to explore the temporal and spatial distribution characteristics of forestry industry clusters.Finally,the fixed effect SDM model is used to analyze the influencing factors of spillover effects and the attenuation boundary characteristics of different urban agglomerations.⑶Results——The forestry industry cluster in China presents the spatial distribution of partial concentration,overall dispersion,southeast coastal-southwest-northeast concentrated,and central dispersed,and forms the forestry industry clusters represented by Harbin-Changchun urban agglomeration,Shandong Peninsula urban agglomeration,southeast coastal urban agglomeration,southeast Guangxi urban agglomeration.The spatial spillover e
