低碳经济发展激励机制研究

我国发展低碳经济需要兼顾经济增长与节能减排的双重任务。通过建立多任务委托代理模型,对政府激励和引导企业通过发展低碳经济最优化经济效益和节能减排效益的激励契约进行了分析。结果表明,政府一方面应根据企业可观测的努力程度来制定不同的激励契约,另一方面需要考虑不同任务间的相关性对企业激励的影响。     

城市森林固定CO2价值评估

本文利用我国第四次森林资源清样调查资料对上海市森林植被碳储量和碳密度的估算结果,结合植物的光合作用过程计算上海市森林固定CO2的能力,采用造林成本法对上海市森林固定CO2的价值进行了评估。笔者希望通过该研究激发人们保护城市森林以维持城市生态系统可持续发展的积极性,并为合理地进行城市森林管理和城市绿化提供参考。另外,利用系统连续的森林资源清样调查资料评估森林植被的固碳价值,能够对我国更好地履行《联合国气候变化框架公约(》UNFCCC),并为依据《京都议定书(》KyotoProtocol)进行环境外交提供帮助。     

国企锦标赛激励效应与制约因素研究

本文尝试从锦标赛的角度为国企竞争理论提供信息经济学模型解释和实证支持。为了达到这一目的,本文从政府干预和共同代理的角度对经典的锦标赛模型进行细化和拓展,以揭示出国企锦标赛激励效应与制约因素,并收集2451家地方国有上市公司披露的薪酬差距数据对理论模型进行实证检验。理论模型表明,薪酬差距的扩大和国企经营者赢得经济锦标赛激励的强化会增加国企经营者的努力水平,因而有利于公司绩效的提升。不过,国企经营者赢得经济锦标赛的激励却受到政府行政干预和共同代理问题的制约。实证结果表明,我国地方国有上市公司薪酬差距与公司绩效显著正相关,而与地方政府行政干预和共同代理问题的严重程度显著负相关,从而支持了理论模型。     

住房市场调控新政能够实现“居者有其屋”吗?——一个动态一般均衡的理论分析

我们建立了一个包括买房和租房决策的DSGE模型,计算房价和房租的动态轨迹,分析六种住房调控政策的影响:提高贷款利率、提高首付比例、对新购房征收房产税、对存量房征收房产税、对小户型免税和对大户型征税。数值模拟发现,这些调控政策通过抑制住房消费来降低房价,把购房需求转化为租房需求,从而推高了房租。其中,对新购房征税的效果最小,只能轻微降低房价,却显著推高房租;而对存量房征税会对房价、地价和房租产生极大冲击。     

Does the Connectivity of the Belt and Road Initiative Contribute to the Economic Growth of the Belt and Road Countries?

ABSTRACT

Since the Belt and Road Initiative (BRI) has been implemented for five years, it is time to ask whether the BRI contributes to Belt and Road (BR) countries’ economic growth, and how are the five elements of connectivity implemented between China and its partner countries since the BRI was proposed. This study focuses on the development of the five elements of connectivity between China and the BR countries from 2008 to 2017 using a comprehensive connectivity index extracted from principle component analysis, and then investigating if the connectivity has contributed to the economic growth of the BR countries with quantitative analysis of the fixed effect econometrical model. It is found that Russia, South Korea, and Singapore presented the top three levels of connectivity with China with regard to the overall connectivity index, varying from 1.4 to 2.4. Madagascar and Panama have the lowest level of connectivity with China, with values of ?0.8 to ?1.1. The result of the fixed effect model shows that the connectivity of the BR countries with China contributes to their economic growth. This provides quantitative evidence that the connectivity between BR countries and China has a significant influence on the economic growth of those countries.

浅谈英语听力理解中的心理障碍及其克服方法

听在人类语言交际活动中占有很重要的地位。听、说、读、写——外语学习的基本步骤中，听排第一位。随着高考、大学英语四、六级考试对听力理解，听力测试的要求，学生对其产生的心理障碍也随及增长，引发出被动心理现象，疲倦感觉现象和紧张，恐惧现象。培养和提高听力水平和听力能力，必须从理论上认识听力理解的过程，从心理上克服种种障碍。

Do individual investors learn from their trading experience?

After analyzing retail investors’ stock trades for potential learning behavior, we present evidence that individual investors learn from their trading experience. Initially, we question whether investors’ previous forecasting ability (inferred from prior purchases’ subsequent risk-adjusted performance) affects their future trade profitability and activity. Indeed, as an investor's inferred ability increases, so does her ensuing trade profitability and intensity. Further, because additional investment experience allows more accurate ability inference, we posit that trading experience should help investors obtain better investment performance. Consistent with this hypothesis, not only do excess portfolio returns improve with account tenure, but we also find that trade quality (i.e., average raw and excess buy-minus-sell returns) significantly increases with experience (i.e., calendar time and account tenure). In sum, individual stock investors do learn, and they consequently adjust their behavior and thus effectively improve their investment performance.
