Abstract

COVID-19 is spreading rapidly over the world, which has continued to affect economic performance and the lives of residents. To find a scientific theory for controlling the spread of the COVID-19, restoring economic development, improving people’s lives, based on the literature, theory and practice analysis, the paper makes the following points. 1. Presenting the concept of contactless, including the definition, characteristics, significance. 2. Constructing a space-time locational correlation theory (STLC) to study the operational mechanism of contactless, (1) based on the definition analysis, the scope of action of contactless is divided into three parts: 1) the spatial surface distance between the subject (A) and the object (B) is zero, 2) the spatial surface distance between A and B is not zero but within the effective direct influence range, 3) beyond its effective direct influence range; (2) exploring the mechanism of contactless of A and B under the different scope of action for the 1) same space, same time, 2) same space, different time, 3) different space, same time, 4) different space, different time, respectively. 3. Building a contactless decision-making model, which considers the subject-object cost, environmental cost and safety cost, to minimize the comprehensive cost, and providing a basis for the selection and application of contactless. 4. Discussing it empirically using the COVID-19 as an example to demonstrate the application value and practical significance of the basic theory and mechanism of contactless. Contactless has already played a significant role in the prevention and control of the COVID-19, but there are still imperfections and future research still needs to improve and expand on them. It is expected that contactless will serve social development better.
