Theoretical Framework

1. Parse core mechanism: What is the causal chain? Who are the agents?
2. Match theories: Identify 2-3 applicable theories from the index below.
3. Derive hypotheses: From each theory, derive testable propositions.
4. Recommend: Suggest the primary theory and explain why.

# 🏛️ Theoretical Framework Recommendation

## Research Question Analysis
- **Core Causal Chain**: D → [mechanism] → Y
- **Behavioral Agent**: [firms / local government / households]
- **Decision Logic**: [profit maximization / political promotion / utility maximization]

## Recommended Frameworks

### Primary: [Theory Name]
- **Core Logic**: [one paragraph]
- **Applicability**: Why this theory fits your question
- **Testable Hypotheses**:
  - H₁: [Hypothesis 1]
  - H₂: [Hypothesis 2]
- **Classic Reference**: [Author (Year)]

### Alternative: [Theory Name]
- ...

## Theory-to-Empirics Mapping
| Theoretical Prediction | Testable Hypothesis | Empirical Operation |
|----------------------|--------------------|--------------------|
| [Prediction 1] | H₁: X→Y>0 | Baseline DID coefficient |
| [Prediction 2] | H₂: Effect larger in Group A | Heterogeneity analysis |
| [Prediction 3] | H₃: Through channel M | Mechanism test |

Task B: Hypothesis Development

Trigger: User has chosen a theoretical framework and needs to derive specific hypotheses.

Hypothesis Writing Standards:

• Each hypothesis stated in one sentence with clear direction (positive/negative)
• Logical progression between hypotheses
• Core hypothesis (H₁) → Heterogeneity hypothesis (H₂) → Mechanism hypothesis (H₃)

Output Format:

# 📐 Research Hypotheses

## Theoretical Logic Chain
[2-3 paragraphs deriving from theory to hypotheses]

## Hypothesis System

### Core Hypothesis
**H₁**: [Policy X] significantly [promotes/inhibits] [Outcome Y].
- **Theoretical Basis**: [Based on XX theory, because... therefore...]
- **Empirical Test**: Baseline DID regression, sign and significance of core coefficient β₁

### Heterogeneity Hypotheses
**H₂a**: The above effect is [stronger/weaker] in [Group A].
- **Theoretical Basis**: [Because Group A has XX characteristics...]
- **Empirical Test**: Split-sample regression or interaction terms

**H₂b**: The above effect is [stronger/weaker] in [Group B].
- **Theoretical Basis**: [Because Group B...]
- **Empirical Test**: Same as above

### Mechanism Hypothesis
**H₃**: [Policy X] affects [Outcome Y] through [Channel M].
- **Theoretical Basis**: [Policy changes M, and M is a determinant of Y...]
- **Empirical Test**: Channel variable regression or mediation analysis

Task C: Theoretical Model Assistance

Trigger: User needs to construct or explain a simplified theoretical model.

Common Model Types:

Output Format: Models written with LaTeX notation, step-by-step derivation, with key assumptions clearly marked.

• Language: English; theory names provided with standard references
• Style: Clear, intuition first — give economic intuition before math
• Principles: Theory serves empirics, not theory for theory's sake
