What are the four factors of industrialization?

There are a number of factors that lead to industrialism.  First, technologies for production are necessary.  These technologies can take the form of any mechanized machines from steam powered engines to robotics.  A second important factor for industrialization is a large population from which to draw labor and to sell finished goods.  The third factor for industrialization is the availability of natural resources that can be utilized to make finished goods.  The fourth factor of industrialization is a means for transportation to get the goods to consumers.  This can take the form of highways, but waterways like rivers and seas are more useful.  Another factor for industrialization is the presence of a stable political situation, especially one that supports the idea of manufacturing and the free market.
