Cognitive distance between products

A product requires a certain set of knowledge to make. Thus, different products reflects different set of knowledge. How different are those products in terms of knowledge deployed? Here, we quantify the cognitive distance between products, called inter-product proximity. High product proximity means products deploy similar set of knowledge, while low product proximity means they use relative different knowledge.

Product Space

If we can measure the cognitive distance between products, we can built a product space, a network representative of product proximity. Then, we construct regional product space by depicting provinces’ export onto the network.
