What level is the fourth-level state-owned enterprise?

County-level companies or district-level companies. The higher the level of state-owned enterprises, the larger the enterprise scale, the wider the business scope, the greater the assets and the more employees. Four-level state-owned enterprises usually refer to subsidiaries or branches with smaller scale, narrower business scope, smaller assets and fewer employees, similar to small enterprises such as county-level companies and district-level companies.
