China's economy is in a stage of steady development, and the country has also formulated a transition policy from a manufacturing power to a manufacturing power. This policy has reflected the quality requirements put forward on the one hand with social phenomena and the increasingly affluent conditions in time. This contradicts the quality level of China's manufacturing industry. The standard is an important factor that restricts the product quality assurance process, and whether the role it plays can be recognized by the public and consumers. Therefore, we put forward relevant research questions. Can this standard be used as a signal of product quality to influence consumers' purchasing decisions? If so, whether there are other influencing factors?This study will take the average consumer as the research object, and see the criteria used in the purchase of daily necessities as the premise. Based on this, this study explores whether consumer's cognition of product execution standard affects their purchase decision behavior. If there is a correlation, we will further study whether consumers' differences of standard cognition will affect consumers' trust in product quality, thus affecting consumers' purchasing decision behaviors. This study verifies whether trust plays a mediating role, whether communication behaviors between enterprises and consumers affect consumers' standard cognition and trust of product quality. Based on the literature review and empirical analysis, this study will provide suggestions and countermeasures on how to effectively use product standards and how to make standards more acceptable to consumers.
