When did the supply and marketing cooperative give up the refined oil business?

In the 1990s, all kinds of shops opened by individuals mushroomed in remote towns and villages, which brought great impact to supply and marketing cooperatives with little operating pressure and motivation. Supply and marketing cooperatives began to reform. The core of the restructuring is contracted management, and a few contracted employees continue to operate the original supply and marketing cooperative stores, which is under operational pressure. Employees who are not contracted can only be laid off and receive meager wages. Almost overnight, all the employees of the supply and marketing cooperatives were laid off and became private enterprises of contractors. A considerable number of supply and marketing cooperatives have given up their traditional business in the fierce market competition, and a considerable number rely on property and rent to maintain. At the turn of the century, the national supply and marketing cooperatives can be said to be in ruins, and more than 90% of the companies affiliated to cooperatives at all levels have died.

Along with refined oil, there are traditional businesses of agricultural machinery and agricultural materials.
