中国钢铁产业集中度研究
发布时间：2019-07-07 20:30
【摘要】： 在传统产业组织理论的“市场结构一市场行为一市场绩效”(SCP)分析范式中,市场结构与经济绩效的关系一直是倍受关注的焦点之一。同时,由于产业集中度是刻画市场结构的重要概念,因此,对于产业集中度水平及其变化的决定因素的研究也是非常重要的。 中国是世界钢铁大国,但还不是世界钢铁强国。产业集中度较低是中国钢铁行业的核心问题,并由此导致了中国钢铁产品结构不合理、档次和质量较低、资源消耗较高等方面的问题。尽管我国钢铁工业在过去的20多年里有了较大的发展,早在1996年我国就已成为世界第一产钢大国,并且钢产量连续9年在国际上居于首位,但这并不能说明我国是一个钢铁强国。当今世界钢铁强国如日本、美国、德国和欧盟等都具有较高的产业集中度,从而具备较高的国际竞争力。中国在加入WTO后,如何在保持钢产量的总数量位居世界前列的基础上,提高钢铁产业集中度和国际竞争力,是当前钢铁行业面临的重大课题。 本文从产业组织理论的角度出发,结合世界钢铁产业的发展趋势及其我国国内特有的体制性和制度性原因,以中国钢铁产业作为研究对象,利用年鉴数据,考察我国钢铁产业集中度历年的变化情况及其与利润率之间的关系。结果表明我国钢铁产业集中度与利润率之间存在正相关关系,但是这种相关关系在数理统计上并不是很明显,这种正相关关系是由于我国现阶段大企业较高的经营效率和技术创新水平。然后,对我国钢铁产业集中度的影响因素进行回归计量分析,回归分析的结果是:期初集中度、利润率和生产扩张能力与产业集中度相关,且期初集中度对产业集中度的影响为正,而生产扩张能力对产业集中度的影响因素为负,而利润率在统计上却表现为不显著。最后,根据回归结果分别解释了钢铁产业出现上述结果的原因,提出了提高我国钢铁产业集中度水平的政策建议:利用兼并合作战略,提高产业集中度;切实执行好《钢铁产业发展政策》,形成制度性进入壁垒,促进有效竞争,提高钢铁产业集中度;提高管理水平,加快产品结构调整。

[Abstract]:In the (SCP) analysis paradigm of "market structure-market behavior-market performance" in the traditional industrial organization theory, the relationship between market structure and economic performance has always been one of the focuses of attention. At the same time, because industrial concentration is an important concept to describe the market structure, it is also very important to study the level of industrial concentration and the decisive factors of its change. China is a big steel country in the world, but it is not yet a big steel power in the world. The low degree of industrial concentration is the core problem of China's iron and steel industry, which leads to the unreasonable structure of Chinese iron and steel products, low grade and quality, high resource consumption and so on. Although China's iron and steel industry has made great progress in the past 20 years, as early as 1996, China has become the largest steel producer in the world, and the steel output has been in the first place in the world for 9 years in a row, but this does not mean that China is a strong iron and steel country. Nowadays, the world steel powers such as Japan, the United States, Germany and the European Union all have high industrial concentration, so they have higher international competitiveness. After China's entry into WTO, how to improve the concentration and international competitiveness of iron and steel industry on the basis of keeping the total output of steel in the forefront of the world is an important issue facing the iron and steel industry at present. From the point of view of industrial organization theory, combined with the development trend of the world iron and steel industry and its unique institutional and institutional reasons in China, this paper takes the Chinese iron and steel industry as the research object and uses yearbook data to investigate the changes of the concentration of China's iron and steel industry over the years and the relationship between the concentration and the profit margin. The results show that there is a positive correlation between concentration and profit margin in China's iron and steel industry, but this correlation is not obvious in mathematical statistics. This positive correlation is due to the high operating efficiency and technological innovation level of large enterprises in China at the present stage. Then, the influencing factors of iron and steel industry concentration in China are analyzed by regression econometry. the results of regression analysis are as follows: the initial concentration, profit margin and production expansion ability are related to industrial concentration, and the influence of initial concentration on industrial concentration is positive, while the influence of production expansion capacity on industrial concentration is negative, but the profit margin is not statistically significant. Finally, according to the regression results, this paper explains the reasons for the above results, and puts forward some policy suggestions to improve the concentration level of China's iron and steel industry: making use of the merger and cooperation strategy to improve the industrial concentration; earnestly implementing the "Iron and Steel Industry Development Policy", forming institutional barriers to entry, promoting effective competition and improving the concentration of the iron and steel industry; improving the management level and speeding up the adjustment of product structure.
