Path dependency theory

Path dependency theory, also known as path dependency

Introduction

Once people make a certain choice, it is like taking the road of no return. The force of inertia will make this choice constantly strengthen itself and make it difficult for you to go out easily.

Path Dependence)It was initially demonstrated by Paul A David in 1985 that w Brian Arthur made further expansion. David's story is the current QWERTY keyboard, which is not technically the best, but it firmly occupies the market. In fact, Dvorak obtained the most patent-winning DSK keyboard input speed in 1932. David believes that, for some reason, the QWERTY-type keyboard has the advantage of a small number of other types, considering the compatibility of hardware and software, other users choose QWERTY when choosing a typewriter (the keyboard evolved from a typewriter. In this way, the QWERTY keyboard gradually occupies the entire market. David calls this status "locked ". Later, although the keyboard was more advanced in technology, it was too late.

This not only reminds people of the five pen fonts in the Chinese input method. In the initial stage of the Chinese character input method, because the Pinyin input method is slow and needs to be selected during input, the introduction of the Five-stroke font has a certain advantage. Due to the large population in the Mainland, rapid promotion of five pen fonts. Since then, other new input methods can no longer compete with them. Even if they have technical advantages, they can no longer compete with them.

American economist Douglas North is the first scholar to propose the "path dependency" theory of the system. He believes that there are two reasons for institutional changes: increasing revenue and network externality, and there are significant transaction costs in the economy and society. Whether this idea is true requires further research. Douglas noth successfully explained the evolution law of the economic system with the "path dependency" theory, and won the Nobel Economics Award in 1993.

Noth believes that path dependence is similar to the "inertia" in physics. Once a path is entered (good or bad), it may depend on this path. The established direction of a path will be strengthened in future development. The choices people made in the past determine their current and future options. A good path will play a positive feedback effect on the Enterprise. through inertia and impulse, the flywheel effect is produced, so the enterprise's development enters a virtuous circle. A bad path will play a negative feedback effect on the Enterprise, just like a bad luck loop, enterprises may be locked in an inefficient state and lead to stagnation. Once these options are locked, it is very difficult to get out of the lock.
