粮食安全关乎国运民生。当前,我国农村乱占耕地建房问题突出,对粮食安全造成一定威胁,国务院及其相关部门虽多次加大对农村乱占耕地建房的执法力度,但执法效果仍存在较大提升空间。文章通过对筛选的400个农村乱占耕地建房典型案例进行实证分析,认为当前农村乱占耕地建房执法仍存在执法权横向划分不明确、基层执法权纵向配置不合理、综合执法力度不足、执法队伍业务水平不高等问题,并提出明确划分执法权限、推进部门综合执法、下放行政执法权、提高执法队伍业务水平是突破农村乱占耕地建房执法困境、守牢耕地红线、夯实粮食安全根基的因应之策。

宅基地使用权依托农房转让的制度沿革、司法裁判与实践创新

宅基地使用权依托农房转让的制度沿革经历了从允许到限制的转变,体现了政府政策的强制驱动和利益诱导的结合。宅基地使用权依托农房转让的司法裁判具有明显的被动性,农户在集体经济组织外部转让农房时,法院一般会认定该转让合同无效,但司法政策又为宅基地改革预留了政策空间,体现了原则性与灵活性的统一。在宅基地使用权依托农房转让的实践创新中,国家并没有直接废除宅基地使用权依托农房限制转让的既有路径,径行允许转让,而是秉持审慎原则,独辟蹊径。试点地区宅基地使用权依托农房转让下受让人范围拓展,与集体经营性建设用地入市衔接,与宅基地资格权退出耦合及与宅基地入股、合作打通,均体现了对宅基地使用权权能受限的克服。
