Ever wondered why some industries in your region are booming while others are struggling? Enter the Shift Share Analysis Calculator – your economic detective tool for solving these regional growth mysteries!
What is a Shift Share Analysis Calculator?
Imagine you’re a regional economist with a magic magnifying glass. The Shift Share Analysis Calculator is that magnifying glass, helping you zoom in on the factors driving growth (or decline) in your local industries.
Definition
The calculator is a powerful online tool that:
- Breaks down regional industry growth into three components:
- National Growth Effect
- Industry Mix Effect
- Regional Competitive Effect
- Compares local industry performance against national trends
- Identifies industries with a competitive advantage in your region
In essence, it’s your economic GPS, guiding you through the complex landscape of regional industrial performance.
How To Use the Calculator
Ready to put on your economic detective hat? Here’s how to use this fascinating tool:
- Gather Your Data:
- Collect employment figures for your region and the nation
- You’ll need data for at least two time periods (e.g., 2015 and 2020)
- Organize data by industry sectors
- Input the Information:
- Enter national employment totals for both time periods
- Input regional employment data by industry for both years
- Let the Calculator Work Its Magic:
- The tool will crunch the numbers and break down growth components
- Interpret the Results:
- National Growth Effect: How much growth is due to overall national trends?
- Industry Mix Effect: Is the industry mix in your region favorable?
- Regional Competitive Effect: Does your region have a competitive advantage?
- Draw Conclusions:
- Identify which industries are outperforming or underperforming
- Understand the reasons behind regional economic changes
Remember, the calculator does the heavy lifting, but your insights bring the numbers to life!
3 Examples
Let’s explore three scenarios to see how the Calculator can shed light on different economic situations:
Example 1: The Tech Boom Town
Meet Silicon Valley 2.0, a mid-sized city experiencing rapid growth in its tech sector.
Input Data:
- Region: Silicon Valley 2.0
- Industry: Information Technology
- Time Period: 2015-2020
- Regional Employment Growth: 50%
- National Employment Growth: 10%
Calculator Results:
- National Growth Effect: 10%
- Industry Mix Effect: 15% (IT growing faster nationally)
- Regional Competitive Effect: 25%
Interpretation: The city’s IT sector is not just riding the national wave but has a significant competitive advantage, possibly due to a strong talent pool or favorable business environment.
Example 2: The Struggling Manufacturing Hub
Consider Rustbelt Revival, a city trying to reinvent its manufacturing sector.
Input Data:
- Region: Rustbelt Revival
- Industry: Manufacturing
- Time Period: 2015-2020
- Regional Employment Decline: -5%
- National Employment Growth: 2%
Calculator Results:
- National Growth Effect: 2%
- Industry Mix Effect: -8% (manufacturing declining nationally)
- Regional Competitive Effect: 1%
Interpretation: While manufacturing is struggling nationally, Rustbelt Revival is showing signs of resilience. The positive competitive effect suggests local efforts to revitalize the sector might be working.
Example 3: The Tourism-Dependent Island
Let’s look at Tropical Paradise, an island heavily reliant on tourism.
Input Data:
- Region: Tropical Paradise
- Industry: Hospitality and Tourism
- Time Period: 2019-2021 (including pandemic impact)
- Regional Employment Decline: -30%
- National Employment Decline: -15%
Calculator Results:
- National Growth Effect: -15%
- Industry Mix Effect: -10% (tourism hit harder nationally)
- Regional Competitive Effect: -5%
Interpretation: While the pandemic hit tourism hard everywhere, Tropical Paradise suffered even more. The negative competitive effect suggests a need for diversification or enhanced resilience strategies.

Frequently Asked Questions
Q: How often should Shift Share analysis be conducted?
A: While it can be done annually, many economists recommend a 3-5-year interval to capture meaningful trends while smoothing out short-term fluctuations.
Q: Can Shift Share analysis be applied to non-employment metrics?
A: Yes, while employment is the most common metric, the technique can be applied to other economic indicators like GDP, revenue, or productivity.
Q: How does Shift Share analysis account for new industries?
A: New industries pose a challenge as they lack historical data. Some advanced calculators use proxy data or adjusted formulas for emerging sectors.
Q: Is Shift Share analysis suitable for very small regions or niche industries?
A: While it can be applied, results for very small samples may be less reliable. It’s often more effective for broader regional and industry analyses.
Q: How does Shift Share analysis compare to location quotient analysis?
A: While location quotient measures industry concentration at a point in time, shift share analyzes changes over time. They are often used complementarily for a comprehensive economic analysis.
Conclusion
In conclusion, Shift share analysis is a powerful tool for understanding industry competitiveness and identifying growth opportunities.
By following these five actionable tips and using a Shift share analysis calculator effectively, you can uncover valuable insights that can inform strategic decisions and policy interventions.
