Abstract The contracts are the indispensable legal instruments for any economic transaction. The international sale contract is the main legal instrument by which international commerce is carried out and through which the movement of goods from producer to consumer is ensured within cross-border relations. The sale contract in international commerce is the legal act by which the parties, the seller and the buyer, belonging to different states, commit each other to transfer the property of a good in return for payment of a price. Regarding the general rules applicable to the contract of international sale of goods, they are regulated by the “United Nations Convention on Contracts for the International Sale of Goods from Vienna”. The Convention has adopted uniform rules to govern the international sale of goods contract, if the parties have not chosen expressly for the application of other rules. In this study I present the effects of international sale of goods in the light of the rules of the Vienna Convention of 1980.

国际货物买卖合同的效力

摘要合同是任何经济交易必不可少的法律手段。国际销售合同是进行国际贸易的主要法律工具，通过该法律工具可以确保跨境关系中商品从生产者到消费者的转移。国际贸易中的买卖合同是一种法律行为，属于不同国家的当事方，买卖双方相互承诺转让商品的财产，以换取价格。关于适用于国际货物销售合同的一般规则，由“联合国维也纳国际货物销售合同公约”规范。该公约采用了统一的规则来规范国际货物销售合同，如果当事方没有明确选择适用其他规则。在这项研究中，我根据1980年《维也纳公约》的规则介绍了国际商品销售的影响。
