Market supervision and industry and commerce are both departments responsible for supervising the market economic order, but they are different departments. The industrial and commercial department refers to the State Administration for Industry and Commerce, which is mainly responsible for the management of registration, filing, alteration and cancellation of enterprises, as well as the supervision and investigation of unfair competition in market economic activities. The market supervision department refers to the State Administration of Market Supervision and its subordinate market supervision departments, which is mainly responsible for supervising and investigating all kinds of illegal acts in the market economy, including infringing on consumers' rights and interests, manufacturing and selling fake and shoddy goods, illegal prices, trademark infringement, etc. Although the responsibilities of the two departments are different, they both exist to maintain market economic order, ensure fair competition and protect consumers' rights and interests.
