Okay, I need to create a Wikipedia-style document about "시장 세분화" (Market Segmentation) under the categories of Economy > Market and Business > Marketing. Let me start by understanding what market segmentation is. It's a process where businesses divide their target market into distinct groups based on shared characteristics.

First, the structure: H1 for the title, then an overview section. Next, I should break down the content into sections with H2 and H3 headings. Maybe start with the definition and importance of market segmentation. Then move to types or methods of segmentation. Perhaps include examples and case studies. Also, need a conclusion and references.

I need to make sure the information is accurate and objective. Use terms like demographic, geographic, psychographic, behavioral segmentation. Explain each briefly but clearly. Maybe add some real-world examples to illustrate points.

Check for depth and breadth. Don't just list types; explain why each type matters. Also, ensure readability with simple language. Avoid jargon unless necessary, and if used, provide explanations. For instance, when mentioning psychographic segmentation, define it as based on lifestyle, values, etc.

Include sections like "Types of Market Segmentation" with sub-sections for each type. Maybe a section on the benefits or challenges of market segmentation. Also, think about including how businesses apply these segments in their strategies.

Need to make sure the document is over 800 characters. Let me outline:

1. Title: 시장 세분화
2. Introduction/Overview
3. Definition and Importance
4. Types of Market Segmentation (Demographic, Geographic, Psychographic, Behavioral)
5. Application in Business Strategies
6. Challenges and Considerations
7. Conclusion
8. References

Wait, the user mentioned "필요시 참고 자료나 관련 문서 섹션" so maybe add a references section. Also, check if any code blocks are needed, but since it's about marketing, probably not. Use lists for types of segmentation.

Make sure each H2 has enough content. For example, under Types, each type can be an H3 with explanations and examples.

Check that all sections flow logically. Avoid repetition. Ensure that the explanation is thorough but concise. Maybe include a case study or example in the application section to show real-world use.

Also, verify that terms are correctly explained. For instance, demographic segmentation includes age, gender, income. Geographic could be region, city size. Psychographic might involve personality traits, values. Behavioral could be usage rate, benefits sought.

Need to ensure that each part is accurate. Maybe mention the purpose of market segmentation: better targeting, personalized marketing, improved customer satisfaction, etc.

Check for any possible errors in terminology or structure. Make sure the document meets all the user's requirements: H1, H2, H3, sections, references, and sufficient length.
