矿业用地是直接从市场上获取农村集体所有的土地,这打破了国家垄断的建设用地市场,导致了市场权利结构的改变。对国家所有权的约束就是对集体土地权的解放和扩展,但是又必须对被解放和扩展的新权利设定边界。集体土地权人获得新的权利和自由以后,集体土地用途的保障问题更加突出。在矿业用地的经济利益驱动下,为防止擅自将农业用地改变为建设用地,必须强化农村集体土地的用途管制,严格控制建设用地指标,合力保护耕地面 Mining land is directly from the market access to rural collective-owned land, which broke the monopoly of the construction land market, leading to changes in the market power structure. The constraint on state ownership is the liberation and expansion of collective land rights, but it must also set the boundaries for the new rights to liberation and expansion.
