In macroeconomic system, the development of one industry will pull or push the development of other connected industries, and increase the employment demand of these industries. The driven effect of transportation industry on employment comes from two aspects, one is the direct employment effect generated from transportation industry development; the other is the indirect employment effect generated from the development of connected industries development because of transportation industry. Output elasticity of employment is an important index to measure the industrial employment. By the analysis of the latest data using the input-output model, the output elasticity of employment model, and complex network visualization technology, we found that the transportation industry of Beijing is not only largely driving the effect of employment, but also showed a rising trend year by year, and the transportation industry is becoming more and more important. The study provides a useful reference for the long-term development strategy of Beijing’s transportation industry.
