民事执行担保制度是我国执行程序中一项重要的制度，既有利于保障申请执行人的利益，又可以兼顾被执行人的利益，具有重要的功能和作用。但在理论界与实务界，民事执行担保制度的某些规定和做法存在争议，不利于发挥其应有的作用，有违执行担保的立意。本文结合新出台的司法解释《执行担保规定》，对我国民事执行担保制度进行了较为系统的分析，并提出了相关的完善建议。本文除绪论与结论外，共分四个章节。 第一章阐述了我国民事执行担保制度的法理基础，即概念和性质。文章总结了理论界 关于执行担保概念的不同观点，对比了执行过程中的其他担保，明确我国民事执行担保制度仅指《民事诉讼法》第231条中的担保。文章还探讨了理论界关于执行担保性质的不同观点，指出我国民事执行担保制度是一种具有公私两重性特点、以公法属性为主的复合型法律关系。 第二章阐述了我国民事执行担保制度的构成要件，分为实质要件与形式要件两方面。在实质要件方面，首先需要被执行人申请与申请执行人同意，即双方当事人的合意。其次 是提供执行担保。文章认为，执行担保是向法院提供的担保，且有明确的担保范围和担保方式。最后是法院决定。在形式要件中，首先要有符合法律规定的担保书。文章分析了担保书的内容并认为担保书不属于担保合同。其次是在公司作为担保人的情况下，要有符合法律规定的公司章程、董事会或股东（大）会决议。最后是申请执行人的书面同意意见。为了完善现有法律规定，文章首先建议丰富申请执行人的信息来源，以便申请执行人科学决策，具体措施包括法院积极行使释明权、赋予律师一定的调查权并建立保证人财产申报制度。其次，严禁不恰当地扩大执行担保的范围，并将暂缓执行期间的债务利息纳入执行担保范围。最后，应明确法院审查的范围，对执行担保进行形式上和内容上的全面审查。 第三章阐述了我国民事执行担保制度的法律效果，包括对担保财产进行权利限制、暂缓执行和恢复执行。文章指出，可以通过担保物权公示和查封、扣押、冻结这两种方式对 担保财产进行权利限制。文章还探讨了暂缓执行期限的确立以及与担保期间的关系，认为暂缓执行期限独立于担保期间。文章接着探讨了申请执行人申请恢复执行的条件和方式，认为将担保人变更、追加为被执行人不符合我国执行当事人变更、追加制度的理论基础。文章还分析了担保期间的起算与确立、届满的法律后果以及性质。为了完善现有法律规定，文章首先建议完善执行担保情形下办理担保物权公示手续的相关规定。其次，建议赋予法院依职权查封、扣押、冻结担保财产的权力和在一定情形下依职权恢复执行的权力。此外，文章认为应当严格区分执行担保与第三人自愿代履行。最后，文章建议明确多种担保方式情形下的执行顺位和担保期间的最长期限。 第四章阐述了我国民事执行担保制度的救济程序和惩戒措施。文章认为，鉴于法院在 执行担保的设立中具有最终决定权，应当赋予当事人对该决定申请复议的权利以便于救 济。文章分析了执行标的异议，认为担保人在执行担保中仅适用执行行为异议，并探讨了通过另行起诉的方式对被执行人追偿的合理性。文章还探讨了现有的惩戒措施，认为应当通过完善罚款金额与拘留期限、信用惩戒措施的相关规定来增加惩戒力度，以起到威慑作用。
