摘要：根据投诉时效决定是否受理工程招投标的投诉，需正确适用法律依据，并准确认定起算时间“知道”或者“应当知道”之日。目前对投诉时效的规定并不严格，实践中有必要弱化“投诉时效”的概念。起算时间因实际投诉情况而异，无统一时间，应根据不同情况和相关证据通过论证确定。实践中存在未严格论证投诉时效起算时间即决定不予受理投诉的做法，争议较大，有被复议和诉讼的风险。

Abstract：Whether to accept complaints regarding engineering bidding is determined based on the statute of time limitations for complaints. It requires the correct application of legal provisions and accurate determination of the starting point，which is the date when the complainant "knew" or "should have known." Currently，the regulations on the statute of time limitations for complaints are not strict，and it is necessary to weaken the concept of Complaint Time Limit in practice. The starting point varies depending on the actual circumstances of the complaint and lacks a unified standard. It should be determined through argumentation based on different situations and relevant evidence. In practice，there are instances where the statute of time limitations for complaints is not rigorously examined before deciding to reject the complaint，leading to significant disputes and risks of reconsideration or litigation.
