本研究通过区位熵、核密度和社会网络分析方法，厘清了西藏天然饮用水空间分布格局及其效应。研究发现：（1）西藏天然饮用水企业分布呈现出显著的马太效应特征，拉萨市、日喀则市和山南市是高密度区；（2）注册资金在500万人民币以上的企业经营范围除了生产、销售矿泉水、纯净水外，还包含矿泉水研发、塑料瓶生产、自来水管网安装及维修，茶具和茶叶销售是西藏水企业业务的延伸。本研究以西藏冰川矿泉水有限公司为例给出了企业的控股情况：共控股21家企业，其中，100%控股的四家公司都与5100产品系列相关，该公司控股的企业主要是西藏的本地天然水生产、包装企业，也有少部分上海、北京和广州的营销管理公司。

The spatial distribution pattern of natural drinking water enterprises in Tibet was clarified by means of the methods of location entropy, kernel density and the social network analysis, and its effect study was conducted. The findings are as follows: (1) The distribution of water enterprises in Tibet is characterized by significant Matthew effect, and Lhasa, Shigatse and Shannan are the high-density areas; (2) In addition to producing and selling mineral water, the business scope of enterprises with registered capital of more than 5 million RMB also research and development of mineral water, production of plastic bottles, installation and maintenance of water pipe network, and tea sets and tea sales are the extensions of Tibetan water enterprises.
