Under devolution, responsibility for improving productivity in Scotland is shared across different tiers of government. Key macroeconomic, industrial, innovation and fiscal levers are controlled by the UK central government, impacting on business tax policies, policies to support internationalisation, access to finance and regulatory levers. The Scottish Government controls more of the microeconomic levers to support productivity. This includes the education and skills system, support for business start-ups and broader economic development, infrastructure, and small business growth.
