本文基于非竞争型投入产出法解决市场势力估计中的“统计假象”问题,对中国及其竞争国出口到美、日、德国三大市场的高技术产品的市场势力进行估计。结果表明:“统计假象”问题的确导致了对各国高技术出口品市场势力的高估,发展中国家的高估程度远超过发达国家;中国出口到美国的高技术品中,两类产业的市场势力因“统计假象”的影响而导致的高估最为明显;以非竞争型投入产出法修正出口价格之后进行估计,因“统计假象”引起的市场势力的高估都得到了较好的解决。
Based on the non-competitive input-output method, this article solves the problem of “statistical artifacts” in the estimation of market power and estimates the market power of high-tech products exported to the United States, Japan and Germany by China and its competitors. The results show that the issue of “statistical illusion” does indeed lead to overestimation of the market power of high-tech export commodities in various countries. The degree of overestimation in developing countries far exceeds that of developed countries. Among the high-tech products that China exports to the United States, two types of industries The most obvious overestimation of the market forces due to the influence of the “statistical illusion”; the estimation after the export price is revised by the non-competitive input-output method and the overestimation of the market forces due to the “statistical illusion” Get a better solution.
