The purpose of this study is to discuss whether people’s behaviors would change after the government expanded the range of applying the plastic limitation policy on January 1, 2018. In the beginning, we assumed people’s environmental awareness and action of being eco-friendly would not be affected by the policy. However, according to the questionnaire, it could not be told whether the policy is effective since there are no big differences on the frequency from consumers’ point of view. In addition, according to the strategy that people should spend one dollar buying per plastic bag, consumers actually would choose not to buy plastic bags because they cost money. Moreover, according to the interviews, from the four shop owner’s aspects, all of them believe that the frequency of consumers bringing their own shopping bags does increase. To conclude, people’s environmental awareness and action of being eco-friendly do increase from both consumers and shop owners’ point of view. Therefore, the final finding is that the plastic limitation policy is effective.
