Methodology of 1. Market Research

The methodology of market research refers to the research methods and theories used in market research, which are mainly divided into qualitative research and quantitative research.

1. Qualitative research

Qualitative research is a research method that explores and understands market phenomena in an unstructured or semi-structured manner. Qualitative research is characterized:

-Research purposes: Qualitative research is mainly used to identify market problems, reveal market laws, generate market assumptions, propose market innovations, etc., rather than to verify market assumptions or evaluate market effects.

-Research object: The research object of qualitative research is usually the key participants of the market, such as consumers, customers, competitors, distributors, suppliers, etc., rather than the whole or part of the market.

-Research scenarios: The research scenarios for qualitative research are usually natural or semi-natural environments, such as consumers' homes, workplaces, shopping places, etc., rather than man-made or controlled environments, such as laboratories, questionnaires, etc.

-Research tools: The research tools for qualitative research are usually open-ended questions, observations, interviews, discussions, case studies, etc., rather than closed-ended questions, scales, indicators, statistical analysis, etc.

The common methods of qualitative research are:

-In-depth interview: It is a research method to obtain their views, feelings, motivations, attitudes, behaviors, etc. on market phenomena through one-to-one dialogue with research subjects. The advantage of in-depth interviews is that they can obtain rich, detailed and true information, but the disadvantage is that they require more time, cost and professional skills, and are difficult to summarize and quantify.

-Focus group: It is a research method that invites 6 to 12 research subjects to participate in a topic-related group discussion to obtain their common or different views, feelings, motivations, attitudes, behaviors, etc. on market phenomena. The advantage of focus group is that it can obtain diversified, interactive and innovative information, but the disadvantage is that it needs higher organization and guidance ability, and is influenced and biased by group members.

-Scenario simulation: a research method that involves subjects in a simulation scenario related to market phenomena in order to obtain their reactions, choices, decisions, etc. to market phenomena. The advantage of scenario simulation is that it can obtain intuitive, practical and dynamic information, but the disadvantage is that it requires a high level of design and execution, and it is difficult to simulate the real market environment.

-Project method: is a research method that allows the subject to complete a project task related to market phenomena in order to obtain their knowledge, understanding, creation, etc. of market phenomena. The advantage of the project approach is that it provides in-depth, systematic, and personalized information, but the disadvantage is that it requires a high degree of participation and collaboration, and is difficult to evaluate and compare.

2. Quantitative research

Quantitative research is a method of quantitative measurement and analysis of market phenomena in a structured or standardized manner. Quantitative research is characterized:

-Research purposes: Quantitative research is mainly used to verify market assumptions, evaluate market effects, predict market trends, optimize market strategies, etc., rather than to identify market problems or reveal market rules.

-Research object: The research object of quantitative research is usually the whole or part of the market, such as consumers, customers, competitors, distributors, suppliers, etc., rather than key players in the market.

-Research scenarios: The research scenarios for quantitative research are usually man-made or controlled environments, such as laboratories, questionnaires, telephone interviews, etc., rather than natural or semi-natural environments, such as consumers' homes, workplaces, shopping places, etc.

-Research tools: The research tools for quantitative research are usually closed questions, scales, indicators, statistical analysis, etc., rather than open questions, observations, interviews, discussions, case studies, etc.

The common methods of quantitative research are:

-Questionnaire survey: a research method in which a questionnaire containing a series of questions is issued or sent to the research subjects to obtain their answers or evaluations of market phenomena. The advantage of questionnaire survey is that it can obtain a large amount of standard and comparable information, but the disadvantage is that it requires a high level of design and sampling, and is influenced by the cooperation and honesty of the research object.

-Experimental method: It is a research method that observes or measures the reaction or result of the research object under the condition of controlling or changing certain variables to obtain its causal relationship to market phenomena. The advantage of the experimental method is that accurate, objective and scientific information can be obtained, but the disadvantage is that it requires a high level of operation and control, and is difficult to replicate and popularize.

-Data mining: It is a research method that extracts valuable information from a large amount of data by using statistics, machine learning, artificial intelligence and other technologies to obtain its laws, patterns, trends, etc. of market phenomena. The advantage of data mining is that it can obtain massive, complex and dynamic information, but the disadvantage is that it requires a high level of technology and analysis, and is difficult to explain and apply.

Practice of 2. Market Research
