Abstract: 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.
