Interdependent networks of firms, universities, research institutions, investors, and governments that jointly create, diffuse, and commercialise new technologies, where co-located talent pools, venture funding, shared infrastructure, and knowledge spillovers reinforce one another so that the productive capacity of the whole system exceeds the sum of its individual actors.

Definition
An innovation ecosystem is the web of relationships through which new technologies are conceived, funded, developed, and brought to market. The term deliberately borrows the biological metaphor: like a natural ecosystem, it comprises diverse interdependent actors — startups, incumbent firms, universities, public research laboratories, venture investors, standards bodies, and regulators — whose interactions produce emergent capabilities no single actor could sustain alone. The concept became prominent through studies of Silicon Valley, and was formalised in innovation-systems economics (Freeman, Lundvall, Nelson) and later in Ron Adner’s work on ecosystem strategy.
Innovation ecosystems function through several reinforcing mechanisms. Knowledge spillovers move ideas between organisations via labour mobility, publications, and informal networks. Deep capital markets — particularly Venture Capital — convert research into companies. Anchor institutions such as research universities supply trained people and licensable intellectual property through Technology Transfer offices. Dense local labour markets lower the cost of hiring specialised skills, which in turn attracts more firms: an agglomeration effect that explains why ecosystems concentrate geographically.
In the AI era, innovation ecosystems have become an explicit object of national policy. Access to compute, frontier research talent, and training data now shape where AI capability accumulates, and governments treat ecosystem-building — through research funding, immigration policy, and public compute provision — as a lever in Competition in AI. Concentration is a live concern: a small number of hubs (the San Francisco Bay Area, London, Beijing) capture a disproportionate share of AI investment and talent.
Current Landscape
-
Geographic concentration: AI venture capital is more geographically concentrated than almost any other sector: Dealroom data show the San Francisco Bay Area routinely capturing 35–40% of all global AI venture funding — a share that tightened rather than loosened as global AI VC reached $216.1 billion in 2025 — with the wider US accounting for roughly two-thirds of the world total.
-
Measured concentration at cluster level: WIPO’s Global Innovation Index 2025 (published September 2025) added venture-capital deal locations to its cluster methodology; the top 100 clusters now account for roughly 70% of global PCT patent filings and VC deal activity, with the top ten alone generating around 40% of PCT filings. Shenzhen–Hong Kong–Guangzhou ranked first, ahead of Tokyo–Yokohama and San Jose–San Francisco; London ranked eighth.
-
National rankings: the GII 2025 places Switzerland first, followed by Sweden, the United States, the Republic of Korea (its highest rank ever), and Singapore, with the UK sixth and China tenth.
-
National strategies: the UK’s AI Opportunities Action Plan (January 2025) and Modern Industrial Strategy (June 2025), the EU’s Horizon Europe programme, and the US CHIPS and Science Act all frame public investment explicitly as ecosystem construction — compute, AI Growth Zones, and talent pipelines included.
-
Corporate ecosystems: platform firms cultivate developer ecosystems around foundation models, cloud APIs, and open-source releases, blurring the boundary between corporate strategy and regional innovation policy.
-
Failure modes: ecosystems can hollow out when talent or capital exits faster than it is replenished, or when a dominant incumbent absorbs rather than seeds new entrants — a dynamic regulators increasingly scrutinise in AI markets.
