Innovation typically requires both public and private sector involvement, with each playing crucial roles at different stages. Neither pure market forces nor government action alone consistently produces optimal outcomes for society-wide innovation. Long-term global solutions for challenges like climate change or antibiotic resistance don't emerge from the free market without some form of government intervention.
#### Sector Characteristics
| Sector | Strengths | Weaknesses |
| ----------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| Public/Government | • High-risk, long-term research (e.g., early Internet protocols)<br>• Absorbs innovation risk and accepts necessary failure<br>• Foundational infrastructure (e.g., GPS satellite network)<br>• Multi-stakeholder coordination (e.g., railway standards) | • Slower optimization (e.g., early NASA vs current SpaceX)<br>• Less market-responsive (e.g., nuclear power development)<br>• Will fund dead ends (e.g., some renewable subsidies) |
| Private/Market | • Optimization/scaling (e.g., solar panel cost reduction)<br>• Quick pivoting (e.g., mobile computing evolution)<br>• Resource efficiency (e.g., semiconductor manufacturing)<br>• market driven improvements | • Shorter horizons (e.g., pharmaceutical R&D focus)<br>• Underinvestment in foundations (e.g., grid infrastructure)<br>• Monetizable benefits only (e.g., antibiotic development) |
##### Bridging Institutions
Public-private partnerships and hybrid institutions combine strengths of both sectors:
- University-Industry Research Centers: Advance theoretical understanding through public grants while partnering with industry
- federally funded research centers (FFRDCs) like Los Alamos or MIT Lincoln Lab
- Research Consortiums: Industry pooling resources with government matching (e.g., SEMATECH for semiconductors)
#### The Innovation Chain
##### Key Phases
1. Basic Research: Fundamental discoveries and theoretical advances
2. Early Development: Proof of concept and initial prototypes
3. Commercialization: Market testing and initial products
4. Scale-up: Mass market deployment and optimization
##### Valley of Death
The critical gap between public research funding and private commercial investment where many promising technologies fail due to lack of support.
- electric vehicle battery development in the 1990s required extended support to bridge this gap
- Algal biofuels: Heavy investment but couldn't achieve commercial viability
- solid state or metail-air battery chemistries: several failed attempts at commercialization
