The high-level equilibrium trap is a concept developed by environmental historian Mark Elvin to explain why China never underwent an indigenous Industrial Revolution, despite its wealth, stability, and high level of scientific achievement. Essentially, he claims that the Chinese pre-industrial economy had reached an equilibrium point where supply and demand were well balanced. Late imperial production methods and trade networks were so efficient and labor was so cheap that investment in capital to improve efficiency would not be profitable. At the same time, an intellectual paradigm shift from Taoism to Confucianism among the intelligentsia moved the focus of academic inquiry from natural science and mathematics, which were conceived of under Taoism as investigations into the mystical nature of the universe, to studies of social philosophy and morality under Confucianism. According to Elvin, this produced an intellectual climate that was not conducive to technical innovation. By comparison, the economy of Great Britain at the time of the Industrial Revolution was vastly smaller and less efficient than the late imperial Chinese economy. Labor was comparatively more expensive, and internal trade far less efficient than in China. This produced large imbalances in the forces of supply and demand, leading to economic problems which provided a large financial incentive for the creation of scientific and engineering advances designed to address them. At the same time, the Enlightenment had shifted the focus of academic inquiry towards natural sciences, providing the basis for many technical innovations. ==Background== According to Elvin, Chinese knowledge of science, mathematics, and engineering in the 14th century was far more advanced than anywhere else in the world. He presents the case study of the spinning wheel, a device used to assist in the production of yarn from plant fibers which increased the efficiency of a worker by orders of magnitude. An automatic, water-powered spinning wheel for hemp fiber was described in Chinese scientific manuals by the early 14th century; comparable devices would not be invented in Europe until the 18th century. Despite providing an enormous gain in worker productivity, the Chinese spinning wheel fell into disuse over the subsequent centuries and was completely unknown by the 17th century, whereas the mechanical automation of spinning in Europe in the 18th century (from manual spinning wheel precursors of the 13th century ultimately sourced from Asia Minor) led directly to a process of technical refinement and engineering improvements that resulted in the Industrial Revolution and widespread mechanization of production of goods beyond yarn. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「High-level equilibrium trap」の詳細全文を読む スポンサード リンク
