《法国民法典》代表了自由竞争时期资本主义社会最典型的法律渊源。《法国民法典》物权变动的模式采债权意思主义,物权变动规则反映了该法典所确立的自由和平等原则、财产所有权无限制原则及契约自由原则。对《德国民法典》物权变动规则的社会经济原因分析发现,其具有以下特点:第一,物权变动的模式采物权形式主义。第二,注意平衡不同的利益。第三,更加重视交易安全。第四,动产交付规则更加便捷。 The French Civil Code represents the most typical source of law in the capitalist society during free competition. The model of change of real right of “French Civil Code” takes claims of doctrine of meaning and the rules of change of real right reflect the principle of freedom and equality established by the Code, the principle of unlimited ownership of property and the principle of freedom of contract. The analysis of the socio-economic causes of the change rule of the German Civil Code shows that it has the following characteristics: First, the mode of property change takes the formalism of property. Second, pay attention to balancing different interests. Third, pay more attention to transaction security. Fourth, the chattel delivery rules are more convenient.
