这项研究提出了一个简单的两国模型，在该模型中，制造业的RMS可以选择技术水平(高或低)。我们展示了贸易成本和生产率水平如何影响每个国家的RMS的技术选择，在这些国家，采用高科技的固定成本不同。这取决于高科技的生产率水平。特别是，如果生产率处于中等水平，贸易成本不是太低，那么国与国之间就会出现技术差距。在这种情况下，提高高技术国家的生产率会降低采用低技术国家消费者的福利水平。为了弥补技术进步给国家带来的福利损失，应该降低贸易成本。
This study presents a simple two-country model in which rms in the manufacturing sector can choose a technology level (high or low). We show how trade costs and productivity levels affect technology choices by the rms in each country, where the fixed cost of adopting high technology differs. This depends on the productivity level of the high technology. In particular, if productivity is medium and trade costs are not too low, then a technology gap between the countries arises. In this case, improving the productivity of the high-technology country reduces the welfare level of consumers in the country in which low technology is adopted. To compensate for the welfare loss of the country from the technological improvement, trade costs should be reduced.
