PART B – SmartPLS STRUCTURAL MODEL

Measurement Model
| Construct            | Indicators                       |
| -------------------- | -------------------------------- |
| Economic_Perception  | Econ_Benefit, Infra_Dev          |
| Risk_Perception      | Debt_Risk, Sovereignty           |
| Geopolitical_Concern | Geo_Security                     |
| Trust_in_China       | Trust_China                      |
| Media_Influence      | Opinion_Change, Policy_Influence |
| Support_BRI          | Support_BRI                      |


Structural PathsEconomic_Perception  → Support_BRI
Risk_Perception      → Support_BRI
Geopolitical_Concern → Support_BRI
Trust_in_China       → Support_BRI
Media_Influence      → Support_BRI


SmartPLS Bootstrapping Settings
