When technological change occurs, it increases the productivity of factors of production such as labor and capital. This increase could be proportionate across all the factors, or the productivity of one factor might increase by an especially large multiple. In the technical language of economics, technical change could be 'factor neutral' or it could be biased toward one factor.The PIs use firm-level panel data to directly assess whether technological change is biased towards labor or is factor neutral. This is important because other economists working in industrial economics, productivity, and economic growth have made different assumptions about the effects of technological change. This study provides empirical evidence for these assumptions.The research team also analyzes their data to determine how firm R&D activities affect the speed and direction of technological change in specific firms. The result is a more precise measure of the relationship between R&D activities and productivity growth.The bias of technological change influences how goods and services are produced and shapes the evolution of individual workplaces, firms, and entire industries. This project is a step towards understanding the sources of technological progress and the resulting societal impact.

当技术变革发生时，它会提高劳动力和资本等生产要素的生产率。 这种增长可能与所有因素成比例，或者一个因素的生产力可能会以特别大的倍数增长。 用经济学的专业术语来说，技术变化可以是“要素中性”的，也可以是偏向于某一个要素的。PI使用企业层面的面板数据直接评估技术变化是偏向于劳动力还是要素中性。 这一点很重要，因为其他研究产业经济学、生产率和经济增长的经济学家对技术变革的影响做出了不同的假设。 本研究为上述假设提供了实证证据，并通过对数据的分析，研究了企业的研发活动对技术变革的速度和方向的影响。 结果是更精确地衡量研发活动和生产率增长之间的关系。技术变革的偏向影响着商品和服务的生产方式，并塑造了单个工作场所、企业和整个产业的演变。 该项目是朝着理解技术进步的来源和由此产生的社会影响迈出的一步。
