我国茶销售市场的空间布局与影响因素研究

对我国茶销售市场进行空间分布特征的研究,有助于茶产业的供需平衡。本文利用地理集中指数和GIS技术,从空间分布类型、均衡性和分布密度3个方面来分析我国茶销售市场空间分布特征。结果表明,我国茶类经营点整体呈集中化分布,但集聚性稍弱,全国范围内高密度核心地区包括广州、南京和郑州等为核心的周边部分城市,而西部等地区大多未形成相对规模密集区。以地理探测器为研究工具对影响因素进行单体因素驱动力和影响因素交互作用研究确定,人口因素、经济因素、居民生活水平及茶种植和生产分布区域对茶销售市场空间布局影响较大,固定人口和国内贸易水平是主导影响因子,居民收入水平与气候影响力较弱。但是居民收入水平、气候与居民保障水平等指标与其他指标的交互作用效果突出,异质性作用明显。

Research on Spatial Distribution and Influencing Factors of Tea Sales Market in China

The research on the spatial distribution characteristics of tea sales market is helpful to the balance of supply and demand of tea industry.Using geographic concentration index and GIS technology,this paper analyzes the spatial distribution characteristics of tea sales market in China from three aspects of spatial distribution type,equilibrium and distribution density.The results show that the distribution of tea business sites in China is centralized as a whole,but the agglomeration is weak.The high-density core areas in China include Guangzhou,Nanjing and Zhengzhou,while most of the western regions do not formed relatively large-scale intensive areas.Using geographical detector as the research tool,the driving force of individual factors and the interaction of influencing factors were studied.It is determined that population factors,economic factors,living standards of residents and tea planting and production distribution areas have great influence on the spatial distribution of tea sales market,fixed population and domestic trade level are the leading influencing factors,and residents'income level and climate influence are weak.However,the interaction effect of residents'income level,climate and residents'security level with other indicators is prominent,and the heterogeneity effect is obvious.
