基于地理探测器的就业结构对土地开发度影响研究

The impact of employment structure on land development degree in China based on geographical detector

利用地理探测器揭示就业结构对土地开发度的影响及其区域差异,旨在为新常态下差别化就业支持政策与建设用地规模合理控制提供政策依据。结果表明,①2000—2016年,中国第一产业就业人口及其比例不断下降,第二产业就业人口及其比例呈先增加再缓慢下降的趋势,第三产业就业人口及其比例持续增长,东、中、西地区3个区域就业结构变动有所差异。②2009—2015年,全国第一二三产业就业人口对土地开发度均有显著影响。东部、中部、西部地区3个区域土地开发度的主导驱动因素有所差异,东部地区第二三产业就业人口对土地开发度影响较显著,中、西部地区第二产业就业人口对土地开发度有显著作用。劳动力不同就业行业对土地开发度的影响也存在区域差异。

Using geographic detector to reveal the impact of employment structure on land development degree (LDD) and its regional differences,which provides mechanistic information for formulating different employment support policy and rational control of construction land scale. The results showed that, during 2000-2016, the number and proportion of the first-class are declining continuously, the number and proportion of the second-class employees are increasing at first and then slowly declining, and the number and proportion of the third-class employees is increasing steadily, and it shows a significant growth after 2012. There are differences in the changes of employment structure among the three regions of the east, the middle and the west. During 2009-2015, employees in the first, second and third industries all have a significant impact on LDD in China. The dominant driving factors of LDD in the three regions are different. The employment population of the second and third industries in the eastern region has a significant impact on LDD, and the second industry practitioners in the central and western regions have a significant effect on LDD. There are also regional differences in the impact of different employment sectors on LDD.
