Besides PetroChina, Sinopec and CNOOC, why are there local enterprises in Shaanxi?

There are no political reasons, there are historical reasons. Now that oil seems to be making money, everyone has an idea. In fact, it used to be the same as other state-owned enterprises, nothing special. At that time, there were many local oil production and refining enterprises, and the local oil production and refining enterprises in Shaanxi also developed before. Later, the state integrated oil refining enterprises and integrated oil enterprises in other places into state management. The predecessor of Shantuo was also included, but at that time, the enterprise was very small and backward, and the local state-owned oil enterprises were unwilling to bring it into management, thinking it would be a drag, so they treated it negatively. To put it bluntly, they are unwilling to accept it. After a while, it was forgotten, and no one cared about it anymore, so it leaked. Later, the oil was a little hot, and both PetroChina and Sinopec wanted to collect it. At this time, the local government saw the benefits and Shaanxi withdrew. So there's nothing we can do. It also caused the present situation.
