【摘要】:IPO是上市公司在證券市場上第一次大規(guī);I資行為,而股權再融資則是上市公司進行的第二次圈錢。隨著我國經(jīng)濟的迅猛發(fā)展,市場制度的逐步完善,上市公司的成長速度也越來越快,甚至有些大企業(yè)已經(jīng)逐步開始實施國際化戰(zhàn)略。因此上市公司需要大量的資金來支持企業(yè)的快速發(fā)展,股權再融資就成為其首選的籌資渠道。然而在經(jīng)濟發(fā)達國家的證券市場上,上市公司卻很少采用股權再融資方式籌集資金,因為種種跡象表明在進行股權再融資之后,上市公司的業(yè)績會出現(xiàn)下滑,但是我國的上市公司卻是越來越熱衷于進行股權再融資。因此,對上市公司的股權再融資效應及其影響因素進行研究,具有一定的理論和現(xiàn)實意義。 本文選取2006年-2008年三年間在滬深兩市進行增發(fā)和配股的A股上市公司作為研究對象,并選取主營業(yè)務利潤率、主營業(yè)務收入增長率、總資產(chǎn)收益率、凈資產(chǎn)收益率四項財務指標來衡量上市公司經(jīng)營績效的變化情況,,通過描述性統(tǒng)計方法分析了上市公司股權再融資前后五年的績效變化情況,并就其變化是否顯著進行均值T檢驗。通過研究結果發(fā)現(xiàn)上市公司在實施增發(fā)后業(yè)績出現(xiàn)了顯著性下降,但在配股后并未出現(xiàn)顯著性下降,而且配股后的業(yè)績好于增發(fā)。然后,本文用多元逐步回歸方法對上市公司增發(fā)后經(jīng)營業(yè)績變化的影響因素進行了深入的分析。通過實證研究發(fā)現(xiàn),增發(fā)再融資前一年上市公司自由現(xiàn)金流量以及市凈率與增發(fā)再融資后公司的經(jīng)營業(yè)績下降顯著相關。而增發(fā)前一年的資產(chǎn)負債率和股權集中度對上市公司經(jīng)營業(yè)績的變化雖然也有一定的影響,但在實證檢驗時并不顯著。 最后,本文深入分析了造成我國上市公司再融資效應低下的原因,并且提出了一系列有針對性的政策建議。比如應該堅決杜絕在上市公司中普遍存在的盈余管理行為,完善上市公司的組織結構并建立良好的薪酬激勵體系,逐步改進在證券市場中上市公司進行增發(fā)或者配股的準入制度,同時還要加強對上市公司對募集資金使用效率的監(jiān)管。
[Abstract]:IPO is the first large-scale financing behavior of listed companies in the securities market, while equity refinancing is the second round of money for listed companies. With the rapid development of our economy, the market system is gradually improved. The growth rate of listed companies is also growing faster and faster, and even some large enterprises have started to implement internationalization strategy gradually. Therefore, listed companies need a lot of funds to support the rapid development of enterprises. However, in the stock market of developed countries, listed companies rarely use equity refinancing to raise funds. Because of various indications that after equity refinancing, the performance of listed companies will decline, but China's listed companies are increasingly keen on equity refinancing. It is of theoretical and practical significance to study the equity refinancing effect of listed companies and its influencing factors. This paper selects the A-share listed companies in Shanghai and Shenzhen Stock Exchange from 2006 to 2008 as the research object, and selects the profit margin of the main business and the growth rate of the main business income. Total return on assets, return on net assets, four financial indicators to measure the operating performance of listed companies, through descriptive statistical analysis of listed companies before and after equity refinancing before and after five years of performance changes. The results show that the performance of listed companies after the implementation of the IPO has a significant decline, but there is no significant decline after the rights issue. And the performance after the rights issue is better than the additional issue. Then, this paper uses the multiple stepwise regression method to analyze the influencing factors of the change of the operating performance of the listed company after the issuance. The free cash flow and price-to-book ratio of listed companies in the year prior to refinancing were significantly correlated with the decline in operating performance of the companies after refinancing. However, the asset-liability ratio and equity concentration ratio of the year before the additional issue had a significant impact on the business operations of the listed companies. Changes in performance, though, have a certain impact. However, the empirical test is not significant. Finally, this paper analyzes the causes of the low refinancing effect of listed companies in China. And put forward a series of targeted policy recommendations. For example, we should resolutely put an end to the common earnings management behavior in listed companies, improve the organizational structure of listed companies and establish a good salary incentive system. We should gradually improve the access system of the listed companies to issue additional shares or issue additional shares in the stock market, and at the same time strengthen the supervision of the efficiency of the use of the funds raised by the listed companies.
