【摘要】：創(chuàng)業(yè)板的設立宗旨是服務高科技、創(chuàng)新性企業(yè)。因此創(chuàng)業(yè)板的上市標準不同于成熟的主板市場。同時由于企業(yè)的初生性和未來發(fā)展模式的不確定性,投資創(chuàng)業(yè)板企業(yè)的風險更高。所以,在創(chuàng)業(yè)板首發(fā)限售股解禁之后,普通投資者會面臨更大的風險。本文分析了創(chuàng)業(yè)板首發(fā)股解禁對企業(yè)業(yè)績的影響,并對創(chuàng)業(yè)板今后的改進方向進行了討論。 我國創(chuàng)業(yè)板成立的時間不長,學術界一般以主板市場為研究對象,而研究創(chuàng)業(yè)板則受到成立周期短、樣本有限等客觀條件的限制。根據(jù)文獻搜索結果,目前的學術界研究集中在兩個方面：1、研究限售股解禁對股票市場股價的影響；2、國企股份改制對公司績效的影響。很少有人研究的首發(fā)限售股解禁對創(chuàng)業(yè)板公司的業(yè)績影響。在本文中,我們基于市場的統(tǒng)計數(shù)據(jù),研究創(chuàng)業(yè)板“首發(fā)限售股”解禁對“企業(yè)績效的影響”。通過分析財務指標,讓大家對創(chuàng)業(yè)板的金融服務體系有一個全面的、清晰的認識。并就如何增強上市公司的治理能力,提高公司的績效展開了討論。 本文的特點是從實證的角度來研究首發(fā)限售股解禁對企業(yè)績效的影響。其中的研究對象包括財務指標、主成分和企業(yè)綜合績效。先用配對樣本T檢驗對財務指標進行對比分析,比較了上市前后的財務指標是否有顯著性變化。再用對十幾個財務降維,提煉出盈利能力、償還能力、成長能力、營運能力等幾個主成分,最后得到主成分權重系數(shù)表達的綜合績效表達式。其中采用配對樣本T檢驗各項指標的前后顯著性變化,總結出解禁前后企業(yè)的整體運營狀況。全文分為以下部分： 第一章闡述了研究的背景、意義、思路、框架及創(chuàng)新點。 第二章系統(tǒng)地介紹了委托代理理論、控制權理論、產(chǎn)權理論等基礎理論,以及學術界在大小非解禁、公司治理、股價影響等方面的著作。 第三章是論文的主體部分。包括研究方法綜述、指標的選取、主成分降維、綜合績效分析。 第四章先分析了解禁對公司的財務指標及綜合績效造成影響的原因,再針對如何增強上市公司的治理,提高公司的績效進行了討論。并對下一步的研究進行了展望。
[Abstract]:The purpose of establishment of gem is to serve high-tech and innovative enterprises. Therefore, the listing standard of gem is different from that of mature main market. At the same time, due to the incipient nature of enterprises and uncertainty of future development mode. The risk of investing in gem enterprises is higher.

Extract several principal components, such as profitability, repayment ability, growth ability, operating ability, etc. Finally, the comprehensive performance expression of the principal component weight coefficient is obtained, in which the paired sample T is used to test the significant changes of the indexes before and after. The whole operation of the enterprise before and after the lifting of the ban is summarized. The full text is divided into the following parts: The first chapter describes the background, significance, ideas, framework and innovation of the research.
