【摘要】:本文首先研究企業(yè)生命周期與風險承擔的關系,然后在構建投資者情緒指數的基礎上,研究投資者情緒對二者關系的調節(jié)效應。研究發(fā)現:企業(yè)處于初創(chuàng)期、衰退期時,其風險承擔較大;處于成長期、成熟期時,其風險承擔較小。高漲的投資者情緒會增加處于不同生命周期企業(yè)的風險承擔。本文進一步從產業(yè)層面對上述關系檢驗,研究發(fā)現對于不同產業(yè)的企業(yè),其生命周期對企業(yè)風險承擔的影響呈現差異,投資者情緒對二者關系的調節(jié)效應也呈現較為顯著的非對稱性。具體來說,第二產業(yè)成長期和成熟期企業(yè)的風險承擔顯著減少,衰退期企業(yè)的風險承擔顯著增加。第三產業(yè)成熟期的企業(yè)風險承擔較小,衰退期的企業(yè)風險承擔較大。高漲的投資者情緒能夠顯著增加第二產業(yè)成長期企業(yè)和第三產業(yè)成長期、成熟期以及衰退期企業(yè)的風險承擔。
[Abstract]:This paper first studies the relationship between enterprise life cycle and risk taking, and then studies the regulatory effect of investor sentiment on the relationship between them on the basis of constructing investor sentiment index. In the period of recession, the risk is larger; In the growth period, mature period, its risk assumption is small. The rising investor sentiment will increase the risk of enterprises in different life cycle. This paper further from the industrial level to test the above relationship. The study found that for enterprises in different industries, the impact of their life cycle on corporate risk-taking is different, and the regulatory effect of investor sentiment on the relationship between them is also more significant asymmetry. During the growth and maturity of the secondary industry, the risks of the enterprises decreased significantly, the risks of the enterprises in the recession period increased significantly, and the risks of the enterprises in the mature period of the tertiary industry were relatively small. The high investor sentiment can significantly increase the risk bearing of the second industry and the third industry growth period, the mature period and the decline period.

【正文快照】: 引言風險承擔是企業(yè)投資決策過程中的重要影響因素。風險承擔反映了企業(yè)在投資決策過程中對投資項目的選擇,高的風險承擔水平預示著企業(yè)更少放棄高風險但預期凈現值大于0的風險性投資項目[1]。企業(yè)所能承擔的風險大小影響投資決策過程中的風險選擇,Acemoglu和Zilibotti[2]研究
