2.8 Methodological limitations
The limitation of this thesis is mainly disported into three aspects. Although some literature reviews have recorded the information about green logistics, most of them actually focused on industrial and other aspects, instead of supermarkets. The authors have to find more information through the interview because of the lack of literature.
The two supermarkets are both large-scale companies in Sweden and China, so there is no direct information from small-scale supermarkets in this thesis. The simple representativeness is the second limitation.
Qualitative method and quantitative method are two research methods mainly used in scientific articles. The authors used qualitative method as the major research method and quantitative method was not used in this thesis. The simple research method is the third limitation.
