Legal analysis: unequal. In business dealings between ordinary individuals, it is best to sign by yourself, and signature and seal cannot replace personal signature. However, in business activities between companies, it can replace the signature, because in business activities, in order to save time and cost, it is impossible for legal persons to participate in every activity; At the same time, contracts signed between companies are generally stamped with the special seal or official seal of the contract, and signing is only a supplementary cooperation.

Legal basis: Article 490 of the Civil Code of People's Republic of China (PRC). If the parties enter into a contract in the form of a contract, the contract shall be established when the parties sign, seal or press their fingerprints. Before signing, sealing or fingerprinting, one party has fulfilled its main obligations, and the contract is established when the other party accepts it. A contract shall be concluded in written form as stipulated by laws, administrative regulations or agreed by the parties. If the parties do not do this in writing, but one party has fulfilled its main obligations and the other party accepts it, the contract is established.
