BOSTON – The echoes of the COVID-19 global health crisis were apparent in the latest edition of The Index of the Massachusetts Innovation Economy, a report that tracks the strength of the Commonwealth’s tech and innovation sectors. Even with net job losses in nine of 11 key tech sectors in 2020, the Massachusetts tech and innovation economy continued to be a top state in terms of total R&D investment ($36 billion in 2018, second only to California), record venture capital investment ($15.8 billion in 2020), and increased investment in higher education per student (up 29.4 percent since 2015).
