Evidential Basis with 根据 in Chinese
根据
The preposition 根据 introduces the information, rule, evidence, or authority on which a conclusion or action is based. Its object forms a complete prepositional phrase before the main predicate. 根据 may also function as a noun meaning basis, but the preverbal construction cannot be split by aspect markers or detached from its object.

Read the structure
The preposition 根据 introduces the information, rule, evidence, or authority on which a conclusion or action is based. Its object forms a complete prepositional phrase before the main predicate. 根据 may also function as a noun meaning basis, but the preverbal construction cannot be split by aspect markers or detached from its object. Keep the model 根据 + Basis + Predicate visible while you compare each sentence.
根据记录，他昨天没来。
According to the record, he did not come yesterday.
Choose the right context
Use 根据 before evidence supporting a conclusion. Use 根据 before a rule or document guiding an action. Place the complete 根据 phrase before the main predicate.
我们根据规定处理这件事。
We will handle this matter according to the rules.
Respect the boundary
Do not put perfective 了 between 根据 and its object. Do not move the basis noun between the main verb and its object. Do not leave preverbal 根据 without an expressed basis.
我们根据了规定处理这件事。
(We handled this matter according to the rules.)
Repair the pattern
Aspect marker splits preposition and object: Prepositional 根据 cannot take 了; perfective 了 attaches to the main action 处理. Basis phrase splits main verb and object: The complete basis phrase 根据规定 precedes the main verb; it cannot interrupt 处理这件事.
我们根据规定处理了这件事。
Use the repaired structure without changing the intended meaning.
