为了能够定量地测量产业间竞争关系的强度，本研究提出了由资源竞争分量和市场竞争分量共同构成的双维度产业间竞争压力概念模型，并给出了基于投入产出视角的竞争压力测度方法。研究发现，产业间竞争压力具有有向性、异质性、对称性和比例性等基本性质；同时，2007年度的中国投入产出数据明确显示，产业间竞争压力服从上尾部具有突出幂律特性的对数正态分布，产业内部竞争强度较高于外部威胁，而且产业内外竞争差距随着产业链递减，产业的竞争地位与其区域总投入或总产出的规模高度相关。

To quantitatively measure the intensity of inter-industry competition relations, this study proposes a two-dimensional conceptual model of inter-industry competition pressure, which is constituted by resource competition component and market competition component together, and also gives out its measure method based on the input-output perspective. The results show that the pressures of competition between industries have a directional, heterogeneous, symmetry and proportions of the basic nature. At the same time, Chinese input-output data in 2007 clearly shows that inter-industry competitive pressure obeys a log-normal distribution with an obviously power law tail, the intensity of competition within the industry is far more higher than external threats from other industries, and the competitive difference between internal and external industry is decreasing with industry chain, the competitive position of an industry is highly relevant to its scale of total input or total output in the region.
