中国土地出让市场网络特征研究——基于社会网络分析

The Research on Network Characteristics of China’s Land Conveyance Market——Analysis based on the Social Network

土地作为核心生产要素之一,其空间流动性及配置优化对于经济发展具有重要意义。基于社会网络分析法,利用中国土地市场网2007-2016年土地交易数据研究土地出让市场的网络特征。研究发现:土地市场具有非常明显的市场分割特性;无论是省间网络还是城市间网络,商服用地和居住用地市场的出强度排名序列都较为相似,而工业用地市场的出强度排名序列则自成体系,这表明工业用地市场和商服用地、居住用地市场是两个独立性较高的不同市场;工业用地市场受到地理临近因素的影响远小于商服用地和居住用地市场,这证明工业企业具有更强的区位流动性,区位转移也较为容易;各城市在居住、商业、工业方面的对外吸引力和开放包容程度各不相同,北京、上海、深圳、广州等大城市的企业在外地获取土地最多。

As one of the core production factors,land's spatial mobility and optimal allocation are very important to the economic development.Using the social network analysis method and the 2007-2016 land transaction data from China land market website,we studied the network characteristics of land conveyance.We find that:(1) The land transfer market has very distinct market segmentation characteristics.(2) Regardless of the inter-provincial network or the inter-city network,the degree of openness ranking for commercial land use and residential land use are ranked similarly,while the degree of openness ranking for the industrial land market is self-contained.Industrial land market and commercial and residential land market are two separate markets with high independence.(3) Industrial lands are affected by geographic proximity factors far less than commercial and residential land markets,thus demonstrating that industrial enterprises have stronger locational mobility and easier location shifts.(4) Each city has different attractiveness,degree of openness and tolerance in residential,commercial and industrial land market.
