V4RIN: visual analysis of regional industry network with domain knowledge

Area of Science:

• Financial Network Analysis
• Information Visualization
• Regional Economics

Background:

• Regional industry networks (RINs) provide specific financial connections within and beyond a region.
• Existing financial network analysis tools are too general for domain-specific RIN analysis.
• Investors and analysts need enhanced methods for exploring detailed RIN data.

Purpose of the Study:

• To develop an interactive visualization system, V4RIN, for analyzing regional industry networks.
• To address the limitations of current tools in handling domain-specific RIN data.
• To improve information exploration efficiency for financial analysts and investors.

Main Methods:

• Collaboration with domain experts to integrate domain knowledge.
• Development of V4RIN, an interactive visualization system.
• Incorporation of data processing methods and support for custom data uploads.
• Utilizing multiple views for comprehensive data exploration.

Main Results:

• V4RIN enables exploration of RIN structure, geographical distribution, and spatiotemporal variations.
• The system was validated through case studies and expert interviews.
• Demonstrated usability and reliability of the V4RIN system.

Conclusions:

• V4RIN enhances the exploration of regional industry networks.
• The system supports domain-specific analysis, aiding financial decision-making.
• Interactive visualization is crucial for understanding complex financial networks.
