【摘要】： 在傳統(tǒng)產(chǎn)業(yè)組織理論的“市場結(jié)構(gòu)一市場行為一市場績效”(SCP)分析范式中,市場結(jié)構(gòu)與經(jīng)濟(jì)績效的關(guān)系一直是倍受關(guān)注的焦點(diǎn)之一。同時(shí),由于產(chǎn)業(yè)集中度是刻畫市場結(jié)構(gòu)的重要概念,因此,對于產(chǎn)業(yè)集中度水平及其變化的決定因素的研究也是非常重要的。 中國是世界鋼鐵大國,但還不是世界鋼鐵強(qiáng)國。產(chǎn)業(yè)集中度較低是中國鋼鐵行業(yè)的核心問題,并由此導(dǎo)致了中國鋼鐵產(chǎn)品結(jié)構(gòu)不合理、檔次和質(zhì)量較低、資源消耗較高等方面的問題。盡管我國鋼鐵工業(yè)在過去的20多年里有了較大的發(fā)展,早在1996年我國就已成為世界第一產(chǎn)鋼大國,并且鋼產(chǎn)量連續(xù)9年在國際上居于首位,但這并不能說明我國是一個(gè)鋼鐵強(qiáng)國。當(dāng)今世界鋼鐵強(qiáng)國如日本、美國、德國和歐盟等都具有較高的產(chǎn)業(yè)集中度,從而具備較高的國際競爭力。中國在加入WTO后,如何在保持鋼產(chǎn)量的總數(shù)量位居世界前列的基礎(chǔ)上,提高鋼鐵產(chǎn)業(yè)集中度和國際競爭力,是當(dāng)前鋼鐵行業(yè)面臨的重大課題。 本文從產(chǎn)業(yè)組織理論的角度出發(fā),結(jié)合世界鋼鐵產(chǎn)業(yè)的發(fā)展趨勢及其我國國內(nèi)特有的體制性和制度性原因,以中國鋼鐵產(chǎn)業(yè)作為研究對象,利用年鑒數(shù)據(jù),考察我國鋼鐵產(chǎn)業(yè)集中度歷年的變化情況及其與利潤率之間的關(guān)系。結(jié)果表明我國鋼鐵產(chǎn)業(yè)集中度與利潤率之間存在正相關(guān)關(guān)系,但是這種相關(guān)關(guān)系在數(shù)理統(tǒng)計(jì)上并不是很明顯,這種正相關(guān)關(guān)系是由于我國現(xiàn)階段大企業(yè)較高的經(jīng)營效率和技術(shù)創(chuàng)新水平。然后,對我國鋼鐵產(chǎn)業(yè)集中度的影響因素進(jìn)行回歸計(jì)量分析,回歸分析的結(jié)果是:期初集中度、利潤率和生產(chǎn)擴(kuò)張能力與產(chǎn)業(yè)集中度相關(guān),且期初集中度對產(chǎn)業(yè)集中度的影響為正,而生產(chǎn)擴(kuò)張能力對產(chǎn)業(yè)集中度的影響因素為負(fù),而利潤率在統(tǒng)計(jì)上卻表現(xiàn)為不顯著。最后,根據(jù)回歸結(jié)果分別解釋了鋼鐵產(chǎn)業(yè)出現(xiàn)上述結(jié)果的原因,提出了提高我國鋼鐵產(chǎn)業(yè)集中度水平的政策建議:利用兼并合作戰(zhàn)略,提高產(chǎn)業(yè)集中度;切實(shí)執(zhí)行好《鋼鐵產(chǎn)業(yè)發(fā)展政策》,形成制度性進(jìn)入壁壘,促進(jìn)有效競爭,提高鋼鐵產(chǎn)業(yè)集中度;提高管理水平,加快產(chǎn)品結(jié)構(gòu)調(diào)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.
