3.1 Research philosophy, approach and sample
This chapter first of all introduces the epistemology, methodology and research tools related to this research from the angle of research philosophy. Then, according to the research philosophy and the research objectives of this study, it puts forward the research hypothesis and designs the questionnaire. Finally it presents the questionnaire survey method and the basic situation of the samples.
3.2 Overview of research philosophy
Epistemology is a philosophical branch that explores the nature, origin and scope of knowledge. Epistemological theory is divided into two schools, namely the transcendental and the posterior. Transcendental theory implies knowledge derived only by reasoning (Kumar, 2014). Posterior theory refers to that acquisition and confirmation of knowledge requires experience. Posterior theory is supported in this study (Bonitsis and Brown, 1997). Therefore, this study uses the research philosophy of positivism, Positivism believes that knowledge is on the basis of natural phenomena, their properties and relations (Kumar, 2014). Information sourced from sensory experience and interpreted through reason and logic constitutes the exclusive source of all authoritative knowledge. Empirical research refers to the research carried out by researchers through collecting observation data in person to put forward theoretical hypothesis or test theoretical hypothesis (Creswell, 2003). Based on the definition of positivist study, this study first collected research related to wine consumption and took deductive research strategy, based on previous research results to put forward the research hypothesis of this study, and it was through collecting a large amount of data and analysis to confirm or overturn the research hypothesis.
Methodology refers to ways, methods that people use to observe things and deal with problems. Objectivism and structuralism are two important types of methodology. In general, worldview influences and determines types of methodology. For example, epistemology of positivism usually corresponds to methodology of objectivism. Therefore, the methodology of this study is objectivism. Methodology of objectivism believes that knowledge is the truth existing objectively, truth is manifested through natural phenomena and social phenomena, and the study of these phenomena can understand the objective reality (Saunders and Thornhill, 2007). Therefore, the research method of this study is quantitative research.
Quantitative research refers to scientific research determining the amount of certain aspects of things, it uses quantity to express problems and phenomena, it is research methods and processes which is through a large number of quantitative data analysis to get significance (Creswell, 2003). Considering from the research aim of this study, it is by collecting data of a large number of consumers’ consumption of wine, through the analysis of the data to understand the common characteristics of their consumption behavior, so the adoption of quantitative study is appropriate.(责任编辑：BUG)
