横纵分析法
Longitudinal and Comparative Research uses two axes. The longitudinal axis traces origins, turning points, and path dependencies; the comparative axis examines peers with consistent dimensions. Together they explain where today's differences came from and which signals may shape the future.
Research subject: 【Enter a product, company, person, technology, industry, or event】.
Use longitudinal and comparative analysis to produce a traceable deep-research report. The research cutoff is the day the task is performed.
Longitudinal analysis:
1. What context and needs led to its creation, and who were the key drivers?
2. What major turning points, successes, and failures did it experience?
3. Which early choices became today's capabilities, path dependencies, or liabilities?
Comparative analysis:
1. Select the most useful comparison subjects and explain why they were chosen.
2. Compare their strengths, weaknesses, and distinctive traits using consistent dimensions.
3. Explain why users, customers, or the market choose it and why they abandon it.
Combine both axes and assess:
1. How capabilities, path dependencies, and constraints formed in the past may shape the future.
2. The three most plausible future paths.
3. The conditions and early warning signals for each path.
Follow these evidence rules:
1. Prioritize primary sources such as official documents, raw data, research papers, financial reports, and interviews.
2. Cite the source and date next to every important conclusion.
3. Separate facts, inferences, and opinions.
4. Present conflicting evidence side by side. If evidence cannot be found, label the claim "not yet verified."
Output the report in this order: core conclusions, key timeline, comparison table, detailed analysis, future assessment, and unresolved questions. The report should be 10,000 to 30,000 Chinese characters or an equivalent level of detail in English. Keep the language accessible and do not pile up sources without analysis.
After copying, replace 【Enter a product, company, person, technology, industry, or event】 with your actual question.
