内容摘要：合同形式，是指当事人合意的外在表现形式，是合同内容的载体。合同形式从种类上分，有口头形式，书面形式；从法律形态上分，有法定形式和约定形式两种。合同形式的制度使命，就是要在社会经济发展的同时充分保证交易的安全，维护交易秩序、促进交易效益并最大化地兼顾合同当事人和社会公共利益的平衡。合同形式对合同的成立至关重要。在合同自由主义下的合同形式欠缺表现出的是违背当事人的意愿，从而导致合同的效力受到影响；在我国国家规定的合同形式强制下的合同形式欠缺虽然不会导致合同不成立，但是由于违反了“应当使用某形式”的指导性规范，亦会使合同效力受到影响，需要通过之后的补偿行为才能得到治愈。处理实际问题时既要注重合同形式又要兼顾合同当事人和社会公共利益的平衡。我们在处理合同形式欠缺的问题上要辨清合同形式的性质，理解合同形式欠缺对于合同成立的影响，妥善处理合同强制和合同自由之间的关系，完善司法者对于处理合同形式欠缺的手段，使我们在处理合同形式欠缺时对合同成立实际问题时更得心应手。
