It can be seen from Figure 2 that in 2009, only five provinces, including Zhejiang, Beijing, and Shanghai, reached or went beyond the intermediate level of coordination development. Eight provinces, including Xinjiang, Qinghai, and Guizhou, were at the very low coordination level of development, and the rest of the provinces were at the primitive level of coordination development. In 2012, the number of provinces that reached or went beyond the intermediate level of coordination development increased to nine, and the newly added provinces included Guangdong, Fujian, Jilin, and Liaoning. By contrast, the number of provinces at the very low coordination development stage was reduced to five (e.g., Xinjiang, Yunnan, and Shanxi), and the rest of the provinces were at the primitive level of coordination development. In 2015, there were eight provinces at the intermediate or higher level of coordination development, among which Liaoning and Guangdong were withdrawn while Hubei was added. The number of provinces with a very low level of coordination development increased to eight, and the newly added provinces included Gansu, Qinghai, and Hebei.
