Advocates of Islamization have often been more concerned with ideology than traditional jurisprudence and there is no agreement among them as to what form a modern Sharia-based "Islamic state" should take. This is particularly the case for the theorists of Islamic economics and Islamic finance, who have advocated both free-market and socialist economic models. The notion of "Sharia-compliant" finance has become an active area of doctrinal innovation and its development has had a major impact on business operations around the world.
