广州城市产业用地供应规模和结构时空特征及机制

根据2007—2020年广州土地供应结果，利用数理统计和空间分析等方法探讨了城市产业供地规模和结构时空特征及机制。研究发现：(1)供地规模和存量用地占比上升，供地向重点开发区集聚。(2)第二产业供地比重下降，制造业下降明显。(3)第三产业供地比重上升，流通和社会公共需求服务部门上升明显。(4)46种行业供地比重变化可分持续下降、持续上升、先降后升、先升后降、波动类型。(5)各圈层供地结构存在差异，但均以房地产为主。(6)供地组合可分5大类，10个亚类，以生产和生活服务部门为主。(7)供地受政策工具、土地市场、集聚扩散、产业互动、产业生命周期和特殊城市本底等方面影响。

SPATIAL-TEMPORAL CHARACTERISTICS AND MECHANISM OF SCALE AND STRUCTURE OF URBAN INDUSTRIAL LAND SUPPLY IN GUANGZHOU

Land resource is an important carrier to support industrial development. The scale and structure of urban industrial land supply reflect the changes of economic development mode, functional orientation, and urban spatial structure. This paper uses Python to obtain the announcement of Guangzhou's land supply results from 2007 to 2020, and uses mathematical statistics and spatial statistics to explore the spatial-temporal characteristics and mechanisms of scale and structure of urban industrial land supply in Guangzhou. The main findings are as follows: 1) Urban industrial land supply and the proportion of inventory construction land has increased. 2) The proportion of land supplied by secondary industry has dropped overall, while the proportion of land supplied by tertiary industry has changed oppositely. 3) From the perspective of three major sectors in secondary industry, the proportion of land supplied for manufacturing industry significantly decreased. 4) Trends in the proportion of land supply in 46 sub-industries can be divided into five main types: Continuous decline, continuous rise, first decrease and then increase, first increase and then decrease, fluctuation. 5) In central urban, suburbs and outer suburbs, real estate land supply accounted for the highest proportion. 6) The combination of industrial land supply can be divided into five categories and ten sub-categories, among which the number of sub-districts with production and living service sector as the main supply type is the largest. 7) Urban industrial land supply is comprehensively influenced by policy tool guidance, land market, agglomeration and diffusion, industrial interaction, industry life cycle, special urban background.
