财政压力、地方政府行为与环境污染

地方政府是生态环境治理的关键主体，财政压力以地方政府行为作为传导变量，对环境污染及其治理效果有深刻影响。实证检验地方政府行为的促污和治污效应对财政压力冲击的响应。结果表明：激励生产型地方政府行为促进污染增加，在财政压力下促进污染增加效应的激化，即压力越大越污染。环境治理型地方政府行为中的环境保护支出对污染治理有效，财政压力对其治污效应有提升作用；排污费征收不治污、反促污，财政高压使其促污效应强化。在财政增支减收、压力不断攀升的背景下，可从治理体制性财政压力诱因、强化对地方政府行为监督和约束以及优化治理工具提升环境治理绩效等方面来平抑财政压力通过地方政府行为引发的环境污染加剧。     

政府质量、科技创新与绿色GDP——中国省际空间溢出效应及区域差异对比

通过构建嵌入政府质量和科技创新因素的经济增长模型，利用中国30个省份2004~2017年的平衡面板数据，实证检验政府质量、科技创新对绿色GDP发展的影响。研究发现：中国绿色GDP存在显著的空间集聚性及明显的区域差异性。在经济权重矩阵影响下，不同地区的政府效率、市场化程度、公平程度和腐败程度对绿色GDP的影响不同，其中政府效率、公平程度能有效促进经济发展较好地区的绿色GDP增长，却会抑制比较落后地区绿色GDP的增长；市场化程度对大部分地区绿色GDP呈现促进作用；腐败程度对地区绿色GDP增长呈阻碍作用。科技创新对各地区绿色GDP均起到积极的促进作用。因此，提升绿色GDP发展水平不仅需要提高地方政府质量，为绿色GDP发展提供符合实际的政策指导意见，还需激活企业科技创新能力，为绿色GDP发展提供有力科技保障。     

政府补贴下考虑企业环保努力的闭环供应链决策分析

在消费者具有环保意识的背景下，分析有无政府补贴时制造商环保努力对各节点企业价格、需求、利润等决策的影响，并进一步探讨补贴在各类最优策略中的作用。研究表明：环保努力能提高两类产品销售价格、扩大新产品需求，但对再制造品需求无影响；存在最优环保努力水平，使无政府补贴下制造商及系统整体利润最大；一定范围内补贴能遏制环保努力导致的再制造品销售价格上升，但对新产品价格无影响，且对零售商来说高补贴未必能带来高收益；消费者环保意识和制造商环保努力可以通过政府补贴影响产品需求和企业收益。     

Comparing online reviews of hyper-local restaurants using deductive content analysis

This study explored consumer-generated online reviews of six hyper-local restaurants in UK and US. A deductive content analysis was carried out involving intrinsic and extrinsic cues of locally grown food. Overall quality, taste, price, region of origin, and menu information were found to be important variables of hyper-local restaurants’ online reviews. Although there were substantially more reviews about price in the UK-based hyper-local restaurants, consumers were found to be more critical of price in the US restaurants. In the UK hyper-local restaurants, a need to provide great selections and variety in the menu offerings was noticed, whereas the US counterparts showcased a need for more creativity in addition to offering a great selection of food and drinks. Region of origin (local) is more important and positive to consumers in the UK restaurants. Contrary to popular beliefs, health benefit and to some extent freshness were not found to be important variables.     

Government contracts and US bond yield spreads: A study on costs and benefits of materialized political connections

In a 1991–2013 sample of bonds issued by US public firms, we find that the cost of debt (yield spread relative to comparable Treasuries) of suppliers to government agencies is contingent on the strategic importance of the supplier's industry. The yield spreads for strategically unimportant government suppliers are higher than for firms that are not government suppliers. If government contracts serve as tangible evidence of political connections, these higher yield spreads indicate that weaker corporate governance as a cost of political connections outweighs the benefits of said connections. For the subsample of government suppliers from strategically important industries, where the benefits of implicit bailout guarantees and revenue stability outweigh the corporate governance problems, the cost of debt is lower than for firms that are not government suppliers. The higher (lower) cost of debt for strategically unimportant (strategically important) suppliers is confined to contracting with the federal government. Our findings are robust to alternative variable and sample specifications, and to endogeneity concerns.     

信息技术与国家审计质量——基于违规金额和地区生产总值的视角

基于信息技术在审计领域的不断应用和“科技强审”“审计全覆盖”的政策驱动背景，探讨信息技术和国家审计质量之间的关系。研究发现，社会信息化环境提高给国家审计质量带来了负面影响，而国家审计机关选择加大信息化投入，开展信息化建设、组织审计人员参加信息技术培训的应对策略，能显著改善社会信息化环境对审计质量带来的冲击，提高国家审计质量。当前信息技术已进入大数据时代，研究结论对国家审计机关持续开展信息化建设和加强信息技术培训提供启示；审计人员更应该提高信息化审计分析技能，提升审计效率，保证审计质量，使得信息技术更好地为国家审计工作服务。     

Optimum government size and economic growth in case of Indian states: Evidence from panel threshold model

This paper investigates the relationship between optimum government size and economic growth using data of Indian states during 1990-91 to 2017–18. Our results derived from panel threshold regression model show a positive and significant impact of government size on economic growth within the estimated thresholds for both aggregate and sub-panels based on income and regions. Once the government size moves above the upper threshold level, then its impact declines and turns to be insignificant. Thus, our findings suggest the policymakers for maintaining the government size within the thresholds limit.     

政府补助企业的主要动机研究——基于我国A股上市公司面板数据的实证检验

上市公司获得的政府补助数额巨大且逐年增长，引起了广泛的质疑，而现有研究对政府补助企业的动机尚无一致的结论。基于理性经济人理论，考虑制度更改和环境变化的影响，以2007—2015年我国上市公司为研究样本，实证检验政府补助企业的主要动机，结果表明：政府补助企业的主要动机在于扩大就业和帮助上市公司“保牌”，最终目的是促进经济的增长；而增加税收和帮助上市公司达到配股要求不是政府补助企业主要考虑的因素，也没有明显证据证明国有企业比民营企业更容易获得政府补助。应完善资本市场退市制度，加强对政府补助的审批和监管，提高政府补助的资源配置效率，并积极引导政府补助发挥更好的社会效益。     

Modelling growth and revenue for Swedish hotel establishments

This paper provides first estimates of the determinants of output growth of Swedish hotels based on establishment data. Growth of overnight stays is modelled as a function of initial size, age, type of accommodation, location and hotel prices measured as average revenues per guest nights. The empirical model accounts for potential endogeneity of hotel prices through the two-stage least absolute deviation model (2SLAD) and the instrumental variable quantile regression method. 2SLAD estimates show a positive and significant relationship between hotel prices and subsequent growth. The relationship is nonlinear with a decreasing impact as the price level increases. Growth of establishments is significantly higher for smaller and younger hotels. An important result is that city hotels, in comparison to tourist and other hotels – which are mainly located outside urban areas (in the mountains and at the sea) – exhibit significantly higher growth rates with a gap between 2.2 and 3.4 percentage points. Furthermore, the positive impact of hotel prices on growth is larger for high-growth establishments. Accommodation prices significantly decrease with the number of local competitors with a non-linear form and increase with size. City hotels and accommodation in the capital city have the highest revenues per guest night.     

基于碳排放的闭环供应链政府奖惩机制研究

温室气体的排放问题已成为国际社会亟待解决的问题，解决这一问题的必由之路就是通过降低产品碳排量实现从源头上减排。本文研究由一个制造商和一个零售商组成的逆向供应链系统，建立了政府实施回收奖惩机制的动态博弈模型，比较分析了有无政府回收奖惩机制两种情形下零售商的回收比例、供应链参与方的期望利润和产品的碳排放总量。研究结果表明，政府回收奖惩机制提高了回收比例和碳减排水平；当再制造减排程度较小时，政府回收奖惩机制降低了碳排放总量；基于消费者低碳偏好的政府回收奖惩机制提高了制造商和零售商的利润，更大程度的降低了产品总碳排放量；政府回收奖惩机制下较小的目标回收率能够最大化零售商利润。
