The Index of the Massachusetts Innovation Economy, published annually since 1997, is a benchmark for measuring the performance of the Massachusetts knowledge economy.

The Index assesses the state’s economic progress and its changing competitive position. Through 25 indicators, the Index gives a comprehensive view of several dimensions of the innovation ecosystem. Using a rich set of US-based data sources, the Index benchmarks Massachusetts against nine Leading Technology States (LTS) to reveal relative strengths and weaknesses. The nine LTS chosen for comparison in the 2009 Index are California, Connecticut, Illinois, Maryland, Minnesota, New Jersey, New York, Pennsylvania, and Virginia.

This year the theme is Massachusetts in the Global Economy and includes international comparisons throughout the indicators where quality data are available.
