逻辑思维 is a compound noun meaning 'logical thinking' or 'rational thought'. 逻辑 itself is a loanword (from Greek λόγος via Japanese) and refers to logic as a system of reasoning; 思维 means 'thinking' or 'thought'. Together they describe the cognitive process of reasoning based on principles of logic, as opposed to emotional or intuitive thinking. In modern Chinese, it is often used in education, philosophy, and problem-solving contexts. Note: the pinyin in the source row appears to be misspelled (sāi should be sī wéi); the standard pronunciation is luó jí sī wéi.
