The most important factor of all may be an open, agile mindset and willingness to embrace change in a fast-moving economy - it is this open mindset which has seen a book provider become a major cloud services provider, a social media network become a major news outlet/distributor, and a search engine engage in everything from satellite imagery to translation services to self-driving cars. E-commerce can help economies open up to new markets abroad and the opportunities of the online economy, but some commentators have suggested it may also leave economies with shallow, or incomplete industrialization vulnerable to a flood of imports from abroad. Indeed, the role of consumers in driving the supply chain has also yet to be clearly understood in many countries.
