摘要土地空置是一个世界性的现象。然而，很少有研究使用定量方法来关注导致小城镇土地空置的微观驱动因素。通过对浙江省N县2014年高分辨率影像的目视检查，确定了该地区闲置土地的有序利用状况，并利用有序逻辑回归分析确定了土地持续闲置的微观驱动因素。研究结果表明，N县2006 - 2012年新供应的农用地转为城镇用地，到2014年仍有57%未利用或未充分利用。微观层面的驱动因素，包括海拔，距离工业园区的距离，在附近的城市土地单位的数量，空置年数，积极影响城市土地利用率。与此相反，坡度、离水源的距离和离建筑区的距离则有负面影响。为解决空置土地持续存在的问题，N县应优先考虑积极土地利用的微观驱动因素，并加强土地供应后的监管。本研究为研究我国小城镇闲置土地的成因提供了微观视角，并为小城镇土地供应方案的制定提供了决策框架。
Abstract The existence of vacant land is a worldwide phenomenon. However, few studies have used quantitative methods to focus on the micro-level drivers that cause land to remain vacant in small towns. In this study, we determined the ordered utilization status of vacant land in N County of Zhejiang Province, China, via visual inspection of high-resolution images captured in 2014, and identified the micro-level drivers of continued land vacancy using ordinal logistic regression. The results show that 57% of the newly supplied land, converted from agricultural land to urban land, released between 2006 and 2012 in N County was still unutilized or underutilized in 2014. Micro-level drivers, including elevation, distance to the industrial park, number of urban land units within the neighborhood, and the vacant years, positively affected the utilization rate of urban land. In contrast, the slope, distance to water, and distance to built-up areas had a negative effect. To address the continuing prevalence of vacant land, N County should prioritize the micro-level drivers of positive land use and strengthen post-land-supply supervision. This study provides a micro perspective for studying the drivers of vacant land prevalence and a decision-making framework in small towns of China to formulate land-supply schemes.
