How Do Land Policies Trigger Land Violations?
Our country is the strictest in the world in implementing a land management system, yet in real life, land violations still occur frequently in some places. Why? Over the past two years, the author visited a number of land violation cases in multiple locations and found that the main cause of land violations is that some local officials collude with relevant leaders of the land and resources departments, using various land policies as a pretext to deceive higher-level governments and farmers. Because these violators not only reap huge profits after the land violation but can also evade legal liability, and some even use this to advance their careers. This has led to a vicious cycle between land violations and political achievement "construction."
