What should firms do with their patent rights when inventors jump ship? This key managerial question was recently addressed in an elegant study by HKUST’s Yanfeng Zheng and a colleague. With critical implications for firms deciding whether to maintain intellectual property after inventors leave, the authors established and empirically tested a framework ... 阅读更多

For Chinese firms, gaining patents for innovations may be a promising way to gain influence in the international arena, according to HKUST’s Jiatao Li and a co-researcher. Such patents act as a powerful signal of technological quality and market potential for U.S. firms who seek to introduce such innovations at home. This research offers novel insights into ... 阅读更多

This paper identifies the causal effect of U.S. multinationals’ technology shocks on their subsidiaries’ and nearby domestic firms’ productivity in China. By combining firm-level data from both the U.S. and China, I match U.S. multinationals with their manufacturing subsidiaries in China and measure the multinationals’ technology shocks to the local firms in ... 阅读更多

We develop a patent analysis approach to discover types of IT innovations and examine their technological and economic impacts. Our empirical investigation is based on 73,120 patents in the medical devices industry filed between 1996 and 2005. Rather than relying on pre-established classifications of IT innovations, we apply textual analysis to patent ... 阅读更多

根据一项考查1990年到2006年美国各州企业所得税变化的研究，公司税赋增高会导致专利数量、研发开支和新产品上市数量下降，但减税似乎并没有促进这类与创新关联的活动。 Abhiroop Mukherjee、Manpreet Singh和Alminas Žaldokas等研究人员剔除了导致创新活动减少的其他原因，包括当地的经济状况。他们發現，在加税的两年内，67%的受影响企业提交的专利項目数量比同等经济条件下不受税赋变化影响的邻州企业提交的专利項目数量少一項。这相当于专利活动总体下降5%。 同样，研发开支下降了4.3%，新产品上市数量下降5.1%。 作者说：“这些研究合在一起，表明企业税赋的效应贯穿于创新的所有阶段。在将创新视为经济增长的关键决定因素的前提下，我们相信这些结果不仅具有学术意义 ... 阅读更多
