国有资本参股影响民营企业绿色创新的偏向性——促进实质性创新还是策略性创新？

采用沪深A股非金融类民营上市公司2009—2022年数据的分析发现，国有资本参股对民营企业绿色创新的促进作用具有明显的偏向性，即显著促进了实质性绿色创新，而对策略性绿色创新的影响不显著。机制分析表明：国有资本参股程度提高有助于民营企业获得更多的环保补助和政府补贴；环保补助（政府补贴）增加可以显著促进民营企业实质性和策略性绿色创新，且对策略性绿色创新的促进作用更大；国有资本参股对环保补助（政府补贴）促进民营企业实质性和策略性绿色创新分别具有显著的正向和负向调节作用。因此，国有资本参股具有资源获取效应和治理改善效应，可以帮助民营企业获得更多的创新资源，也能够缓解委托代理问题，进而在促进民营企业绿色创新的同时形成实质性创新偏向。进一步的异质性分析表明，国有资本参股促进民营企业绿色创新的偏向性在绿色发展意愿较弱、非重污染行业、环境规制强度较小地区的民营企业中更为明显。应在持续推进企业混合所有制改革的同时，重视并解决好企业的委托代理问题，提高民营企业的绿色发展意愿，促进民营企业绿色创新的质量提升。

Security Choice, Information Effects and Firm Characteristics: A Factor Analytic Approach

Abstract:   We examine the marginal choice between debt and equity securities using a factor analytic approach. This data reduction property eliminates the need to select the one best variable to proxy for a particular theoretical construct. Our results reinforce numerous existing findings using traditional methods and suggest both static tradeoff and asymmetric information based considerations are relevant in determining security choice. Two new results are presented related to the accounting liquidity of the firm. First, the preference for equity is increasing with liquidity as suggested by the window of opportunity hypothesis. Secondly, the market response to equity issuance announcements is inversely related to the liquidity of the firm. Profitability and growth measures support Jensen's (1986) agency cost of free cash flow as a potential explanation for the second finding.

THE TEN COMMANDMENTS FOR OPTIMIZING VALUE-AT-RISK AND DAILY CAPITAL CHARGES

Abstract.  Credit risk is the most important type of risk in terms of monetary value. Another key risk measure is market risk, which is concerned with stocks and bonds, and related financial derivatives, as well as exchange rates and interest rates. This paper is concerned with market risk management and monitoring under the Basel II Accord, and presents Ten Commandments for optimizing value-at-risk (VaR) and daily capital charges, based on choosing wisely from (1) conditional, stochastic and realized volatility; (2) symmetry, asymmetry and leverage; (3) dynamic correlations and dynamic covariances; (4) single index and portfolio models; (5) parametric, semi-parametric and non-parametric models; (6) estimation, simulation and calibration of parameters; (7) assumptions, regularity conditions and statistical properties; (8) accuracy in calculating moments and forecasts; (9) optimizing threshold violations and economic benefits; and (10) optimizing private and public benefits of risk management. For practical purposes, it is found that the Basel II Accord would seem to encourage excessive risk taking at the expense of providing accurate measures and forecasts of risk and VaR.
