河北省实施排污权交易的实践与反思——基于河北省满城县经验的探讨

排污权交易作为环境控制政策的手段之一,已成为备受关注的环境经济政策。河北省满城县进行了排污权交易的试点探索,在实践中存在不少问题和困惑,诸如：排污权性质、排污总量的确定、交易价格等都需要进一步研究和探讨。     

房地产住宅价格影响因素的实证分析——以沈阳市为例

住宅价格是房地产市场的晴雨表,能够反应房地产市场的供需情况,以及政策的影响。本文通过对沈阳市住宅价格影响因素进行分析,确立研究指标,并借助沈阳市2002年到2011年统计数据,运用Eviews软件对数据进行回归分析,得到沈阳市商品住宅价格变动回归方程,从而为房地产企业决策及政府制定政策提供理论依据。     

中国房地产投资结构研究

由粗放型外延扩张转向集约型内涵化发展是中国房地产持续发展的必然要求,而产业内部结构优化无疑是实现这一转变的根本途径,针对这一问题,本文从时空、主体、用途三方面深入分析了中国房地产投资结构,揭示了其低度化的现状,阐述了产业投资结构优化的目标及具体对策。     

技术独董、经济政策不确定性与企业创新产出

创新产出是企业创新能力的直观体现,也是企业价值创造的源泉。以2008—2017年披露了专利授权信息的中国A股上市公司为样本,研究了独立董事技术专长对企业创新产出的影响。结果显示：（1）技术独立董事显著地促进了企业创新产出,且这种促进作用受到经济政策不确定性的负向调节;（2）技术独立董事是通过提高企业的创新投入来促进企业的创新产出的;（3）技术独立董事兼职席位与企业创新产出呈倒U型关系。根据上述研究结论,企业应当增加技术独立董事的引入并适当限制技术独立董事在其他企业兼职的行为,以充分发挥技术独立董事的创新驱动效应,提高企业创新产出。     

The Impact of Unionization Structures with Heterogeneous Firms and Rent‐Sharing Motives

How are unemployment and output affected if wages are set on the sector level rather than firm level? We take a new look at this question, allowing for heterogeneous firms and rent‐sharing motives. Without these motives, employment and output are lower under sector‐level wage‐setting due to higher wage markups. With rent‐sharing motives, however, firm selection is higher under sector‐level wage‐setting, which tends to increase employment and output, thus counteracting the markup effect. Simulations show that the firm‐selection effect decreases the difference between the two unionization structures substantially but it does not change the signs of the effects on output and employment.     

On wage- and profit-led demand regimes: learning from the evidence

Abstract

This paper contributes to the empirical research around the “wage-led” or “profit-led” demand regimes. It first reviews how Kalecki, and then Steindl, approached the relationship between economic growth and income distribution. Then, empirical analysis carried out under the probabilistic approach to econometric modeling shows statistical evidence, estimated through cointegration analysis, that in the long run, in three very open economies—Mexico, France, and Korea—the wage share is positively associated with demand and output. It finally discusses the macroeconomic dilemma that almost all countries have to face, i.e., a positive effect of a high-wage policy on demand and employment may diverge from a negative effect on output compatible with external equilibrium.

Optimal investment and production decisions and the value of the firm

We explore the effects of uncertainty on a firm that can respond by modifying its investment or production schedule (or both simultaneously) to variations in output price. Investment may increase capacity and/or reduce costs. We consider a firm with finite resources.Our model uses option theory instead of the more traditional net present value framework. One of the early papers using this approach is Brennan and Schwartz (1985) in which an investment project to extract a finite natural resource is valued. In that paper, the value of the firm is a function of two state variables, the finite resource to be extracted (output to be produced in the future) and the commodity spot price. In order to maximize firm value, the manager can respond by modifying one control variable, the production level. In our model we handle instead three state variables (spot price, resources, accumulated investment) and two control variables (production rate and investment rate), and solve numerically.We obtain both the value and the optimal policy of a firm that has investment projects that increase capacity and/or reduce costs and illustrate optimal policies as resources and available investments decrease over the life of the firm. Firms may start by only investing, then invest and produce, to end only producing.We thank Scott Wo, the referee and the editor for their comments and suggestions.

论我国房地产市场预警系统的建立

建立房地产市场预警系统有助我们在恰当的时候采用正确的房地产宏观调控措施促进房地产市场健康发展。本文将房价收入比、房价租金比、租金收入比、房地产价格增长率与GDP增长率之比、商品房空置率5个指标作为房地产市场预警统计指标,并对它们的预警区间做出界定,然后根据每个指标的统计数据,确定警兆的警级,结合警兆的重要性进行加权综合,综合成一个指数,这样就可以用一组类似于交通信号灯的标志把当前的房地产市场状态直观地表达出来,用以判断房地产市场过热或衰退的程度,来制定房地产宏观调控的方向。     

关于解决我国物业税“空转实”难点问题的研究

目前,我国“空转”物业税的计税依据是房产评估价的70％,而“房产评估价”与房产的房龄、朝向、装修状况、周边设施等多个因素相关,致使评估工作复杂,税收的公平与效率难以体现。基于此,文章提出了以“房产原值”为基础上浮一定比例为“空转”物业税计税依据的全新观点,并从税收公平与效率的视角对这一观点进行了可行性分析。
