The word "生产" is formed by combining two independent pictophonetic characters, each contributing a core semantic idea to create a new, composite concept. The first character, 生, originally depicted a plant sprouting from the earth, conveying the fundamental ideas of birth, growth, and generation. The second, 产, whose traditional form 產 incorporates a cliff radical (厂) over a sprouting plant (生), emphasizes the idea of producing or yielding something from a source. When joined, they create a conceptual sequence where 生 (to generate) naturally leads to 产 (to yield), thus visually and notionally representing the complete process of "production", from the initiation of life or creation to its tangible output.
