There are many reasons, such as backward education, limited resources and single economic structure, but I think the most important reason is that the state does not attach importance to Hainan. There are almost no investment projects of more than 100 billion in Hainan, such as the cross-sea bridge that has been dragged on for so many years, which shows that the state does not attach importance to Hainan at all. In addition to the so-called "international tourist island" that swindles money, house prices have gone up, and prices have also gone up, but the lives of local people are still not so good. If this trend continues, Hainan will not develop at all.
