中文摘要：

以河南省焦作市为例,基于问卷调查法和综合分析法分析了不同土地承包权调整模式下（3—5年、5—10年、10—20年、30年和长久不变）农户的投入意愿和选择取向。研究结果表明：（1）研究区域农户对土地承包权调整相关政策的认知和了解度较高。（2）无论是经营自家承包地还是租用他人承包地,随着承包期限（或租用期限）的延长,农户的投入意愿逐渐提高。（3）受访农户总体上希望土地承包期限延长,但仍有近50%的农户希望定期调整土地承包权。研究结论表明,提高农户对现行农村土地承包权期限、承包方的责任和义务的了解和认知度,有利于激励农户对农地的投入意愿;土地承包权的稳定性是影响农户对农地投入的决定性因素。国家应进一步保持农村土地承包权的总体稳定性,强化农地承包权的用益物权属性;不同类型的农户对土地承包权调整模式的选择取向具有较大差异性,反映出土地承包权稳定性下正效应（促进农户投入,提高农地集约度）和负效应（较大比重农村人口＂生而无地＂的不公平性）的共存性,应在保持土地承包总体稳定的基础上,考虑家庭人口变动和农村人口迁移进行土地承包权的局部调整。
