Question

discuss the characteristic of proto-industialization in Britain and explain why is argued that it paved the way to industrial proper?

Answer 1

The concept of proto-industrialization became an influential one in economic history in the 1970s and 1980s. The term refers to a system of rural manufacture that was intermediate between autarchic feudal production and modern urban factory production. Variously described as rural manufacturing, domestic manufacture, cottage industry, and a "putting-out" system, it was a dispersed system of production that used traditional methods of production and extensive low-paid rural labor to produce goods for the market, both domestic and international. Unlike modern capitalist manufacturing, proto-industrialization did not depend on rising labor productivity as a source of higher profits; instead, merchants increased the scale of their businesses by extending production to additional households and workers. 

One of the first to use the term was Franklin Mendels in 1970 (link), who applied the concept to extra-urban manufacturing in Flanders in the eighteenth century.  Peter Kriedte, Hans Medick, and Jurgen Schlumbohm's Industrialization Before Industrialization provided an extensive historical and theoretical treatment of the phenomenon in 1977.
It has long been known that industrial commodity production in the countryside for large inter-regional and international markets was of considerable importance during the formative period of capitalism.
