Research on the Path of Improving Innovation Efficiency of High-Tech Enterprises from the Perspective of New Productivity<br>—A Theoretical Analysis Framework

Under the strategic background of accelerating the evolution of global scientific and technological innovation and developing new productivity in China, high-tech enterprises, as the core carrier, are facing the efficiency dilemma of “high R&D investment and low achievement transformation”. This paper breaks through the static perspective of the traditional Solow residual value model, and reconstructs the theoretical connotation of innovation efficiency based on the triple dimensions of technological revolutionary breakthrough of new productivity, innovative allocation of factors and deep industrial transformation. By deconstructing the dynamic coupling mechanism of technology, factors and industry, this paper reveals the structural resonance of innovation efficiency improvement dependence, and diagnoses the current bottlenecks: three-dimensional imbalance problems such as technology path dependence, lack of data property rights and lagging system adaptability. Based on this, this paper puts forward systematic promotion paths such as technological transition, factor reset, organizational reconstruction and ecological coordination. It is pointed out that the policy level should be changed from “intervener” to “ecological architect”, and three-dimensional empowerment should be catalyzed by system adaptation adjustment, factor marketization acceleration and scene opening. This study provides a whole chain analysis paradigm of “theoretical framework-mechanism diagnosis-path design” for breaking the bottleneck of innovation efficiency, which has theoretical forward-looking and practical guiding value for driving the development of new productivity.
