Answers: C, D, E

Based on the differences in technology carriers, technology transfer can be divided into "physical", "intelligent" and "humanpower" technology transfer Three modes. "In-kind" technology transfer refers to technology transfer caused by physical transfer. From a technical perspective, physical objects that appear in the form of production means and labor products are the materialization and objectification of specific technologies, and the existence of a certain technology can be reflected from them. Therefore, when physical objects move or transfer in space, a certain technology is transferred accordingly. The "intelligent" technology transfer model refers to technology transfer caused by the dissemination and flow of knowledge in certain specialized scientific theories, skills, experiences, methods and other spiritual categories. It does not rely on the transfer of physical objects. This kind of technology transfer is usually called "soft technology" transfer. Commodity transactions in the form of knowledge such as patented technologies, technical know-how, process recipes, and information intelligence on the market are the basic forms through which this technology transfer is realized. "Manpower-based" technology transfer is an older technology transfer model in human society. It is a technology transfer caused by the flow of people. For example, various forms of mobility such as personnel migration, transfer, recruitment, exchanges, off-site training, etc. can trigger technology transfer. This is because, no matter what specific form technology takes, it exists with humans at its core and is understood, mastered and applied by humans. Therefore, the flow of human resources must be accompanied by technology transfer.
