Technological Change as Historical Process: The Case of the U.S. Pulp and Paper Industry, 1915–1940
研究了1915-1940年美国纸浆与造纸工业的技术变革，识别出三种模式并用诱导创新理论框架解释，对理解历史情境下的技术创新机制有参考价值。
Technological changes in the U.S. pulp and paper industry between 1915 and 1940 are chronicled, and three patterns—evolutionary bias, output-increasing innovation in response to technological disequilibria, and differences in the timing of innovations between the 1920s and 1930s—are identified and explained by means of a theoretical framework for induced innovation. The framework conceptualizes technological change as a means for growth-seeking firms to overcome barriers to accumulation and provides a general explanation of induced innovation that is situated in historical time.
