企业创新是国家经济可持续增长的关键,受到管理层意愿的影响,因而需要对内部经营者的权力进行制衡。以2010-2018年我国A股上市公司为研究样本,实证检验管理层权力制衡强度对企业创新投资的影响,以及不同债务约束情境下高商业信用配置、高负债水平的调节效应,此外,还考察了产权性质的差异化影响。研究表明,管理层权力制衡强度越大,企业创新投资水平越高;高商业信用强化了该促进作用,而高负债水平弱化了该促进作用。进一步研究发现,管理层权力制衡强度与企业创新投资的关系在民企中更显著;国企能够更好地获得和运用商业信用,使其高商业信用对该关系的强化效应更显著;民企具有更强的债务约束,其高负债水平对该关系的弱化效应更明显。  相似文献

Can simplifying customs procedures reduce tariff evasion? We measure tariff evasion as the mis-representation of import values in response to increasing tariffs. In a dataset covering 121 countries and the whole set of HS6 product categories in 2012, 2015, and 2017, we show that simplifying border procedures, that is trade facilitation, reduces tariff evasion. Holding tariff rate constant at its mean, improving a country’s overall trade facilitation performance from the 25th percentile to the median reduces tariff evasion by almost 20%. The moderating effect is especially due to improving the pre-shipment legal certainty of customs procedures. Among the potential mechanisms, improving trade facilitation performance is effective in reducing tariff evasion due to under-reporting of import prices, as well as in countries with weaker control of corruption. The results suggest that countries can gradually implement trade facilitation reforms to cost-effectively minimize tariff evasion.  相似文献

近年来,面对经济社会各领域公共风险,河北财政通过减收、增支、加债等方式,有效防控了公共风险的暴发,全省财政经济运行整体平稳,但也导致财政自身风险的累积,体现在财政收入持续增长后劲不足、财政支出保障难度逐步增加、地方政府债务风险存有隐患、其他领域风险趋向财政转移等。防控地方财政经济运行风险,需要充分发挥财政职能,加强财源建设,推动财政收入持续增长;调整支出方向,确保地方财政平稳运行;完善管理机制,防范地方政府债务风险;深化体制改革,消除财政风险转移隐患。  相似文献

The purpose of this paper was to perform a detailed analysis of the challenges faced while developing and using econometric models to forecast future transportation demand. To this end, a comparative analysis of the state of practice and state of the art was undertaken on a concrete example – Viracopos Airport in Brazil. A review of relevant technical and scientific literature identified a number of approaches and each representative example was synthesized into a specification “template”. We then compared the performance of each “template” with the observed demand, through an intra-series forecast. A general finding was that econometric model specifications proved to be somewhat homogenous and simpler in nature, with results indicating a relatively small difference in fit and forecast capability across models. Even with the elimination of what is typically considered the main culprit for deviations – the forecast uncertainty of the explanatory (input) variables – the forecast is still subject to sizeable deviation. To address this issue, we proposed developing some sanity check indexes, particularly relevant for long-term forecasts. We conclude that the challenges faced at the Viracopos Airport Concession were far from econometric ones, that the success of the demand forecast and the concession itself required more than a well estimated econometric model. Finally, regarding investment obligations within the concession agreement, we strongly recommend making them conditional to meeting demand milestones, given the inherent unpredictability in forecasts.  相似文献

庚子赔款是中国近代史上最大一笔赔款,也是以长期债务形式体现的赔款。本文对庚子赔款的债务化偿付安排、利率水平、支付流程及经济影响等进行比较分析。发现:(1)庚子赔款本金4.5亿两,是清政府 1903 年财政收入的 4.33倍,但通过债务化偿付,每年支付赔款占财政收入比重逐步下降;(2)按购买力折算,庚子赔款本金约占1900年中国GDP的2.1%;(3)与当时主要国家长期债务利率相比,庚子赔款4%的利率属于中等水平;(4)将庚子赔款与德国“一战”赔款进行比较,发现赔款本金和占经济总量比重,中国低于德国,但中国每年支付赔款的财政压力高于德国;(5)庚子赔款偿付对近代中国的财税金融产生深刻影响,外籍海关税务司借机成为独立于中国政府的“第二财政”,外商银行藉此强化其“隐性中央银行” 地位,赔款还催生了货币流通的“新周期” 和“新危机”。总体上,赔款的债务化偿付安排不仅受政治外交形势主导,也与金融机构特别是银行跨国经营存在密切联系。赔款的经济影响不仅取决于偿付总量,也取决于经济治理能力和财税金融制度。国家财税金融制度落后,则受到冲击较大。  相似文献

Soaring levels of public debt in low-income countries are fuelling concerns about their ability to achieve the Sustainable Development Goals, such as free access to primary education. In the late 1990s and 2000s, international financial institutions introduced a series of debt relief initiatives aimed to restore debt sustainability among highly indebted countries. This study examines the impact of these initiatives on primary school attendance. We exploit the temporal variation in the implementation of these policies, in combination with individual-level data from 177 Demographic and Health Surveys covering more than 1.5 million school-age children from 44 low-income countries to implement difference-in-differences and spatial difference-in-discontinuity estimators. Results suggest that debt relief initiatives, by freeing up additional public resources, have significantly contributed to increasing primary school attendance in heavily indebted countries. Impact heterogeneity analysis also shows that debt relief has been effective at reducing wealth-based, intergenerational, religious, ethnic and spatial inequalities in education. Our results provide robust evidence to assert that debt relief, in combination with other financing sources, can contribute to improving educational outcomes in highly indebted poor countries.  相似文献

[目的]在国家高度重视建设"美丽乡村"的背景下,加强乡村聚落空间分布格局及优化研究,对指导新农村建设,实现农村居住地的集约化管理,改善农村现有生态环境,促进城乡协调发展具有重要意义。[方法]文章运用平均最邻近比率、平均分布密度和乡村聚落平均人数描述河南省乡村聚落分布特征,并采用Arcgis10. 2绘制乡村聚落平均分布密度图,从县域和市域尺度分析了乡村聚落的空间分布特征,指明该省乡村聚落发展中存在的问题,并提出了合理性的优化建议。[结果](1)河南省乡村聚落整体呈集聚分布,从空间位置来看,都集中在东北部地区。(2)乡村聚落县域分布密度差距较大,主要表现在中东部地区和东北部地区平均分布密度较大,呈沿交通要道周围分布,东南和西北地区平均分布密度较低。(3)各市级行政单位乡村聚落分布区域差异比较明显,洛阳市、驻马店市、南阳市、信阳市和三门峡市的聚落密度较小,均低于全省乡村聚落平均密度。漯河市、三门峡市、濮阳市和济源市的行政村均人数不足800人。[结论]针对小规模聚落的零散分布和偏远贫困区域乡村聚落的边缘化等问题,今后该省可重点建设中心村,以城带乡发展城边村,同时加大对边缘聚落的改造,结合当地文化优势,发展乡村旅游,提高当地居民进行自我建设的积极性。  相似文献

The study examines and highlights the impact of selected foreign inflows (aid, trade, FDI, debt and remittances) on the economic growth of the South Asian Association for Regional Cooperation (SAARC) countries. The existent literature lacks a comprehensive analysis of the SAARC countries as countries like Afghanistan, Bhutan and the Maldives have largely been ignored due to the shorter time periods of available data. The study is empirical in nature and utilizes panel data techniques on macroeconomic data for the period 2008–2015. Foreign aid and foreign direct investment are found to impact economic growth positively. Foreign debt and trade flows are found to adversely affect economic growth. No relationship is established between the flow of remittances and the economic growth of these countries. The obtained results are robust to different proxy variables and the addition of macroeconomic variables. For the first time, the study provides policy implications based on the data of all SAARC countries. The study recommends focusing on increasing the inflows of resources in the form of aid and foreign direct investment (FDI) from the developed world to achieve higher economic growth.  相似文献

As the formal process of Brexit has already started, there is much uncertainty about Brexit's impacts on Britain's social, political and economic future. This paper examines the economic impact. After briefly discussing some significant EU treaties that serve as the background materials, it presents the key arguments advocated by the leave and remain camps. The economic impact depends critically on the negotiation outcomes. Aside from the debate on the divorce costs, there are numerous issues that must be negotiated, such as immigration, trade in goods, services, agriculture, fisheries and financial regulations. We discuss various scenarios of possible new trade regimes, resulting in different impacts on the UK economy. With each side having its bargaining chips to play, the trade‐offs between “give and take” in the negotiation game are analysed. Considering various strategic options, this paper urges rationality and cooperation, especially weighing both sides’ entwined economic interests, in addition to their mutual security, defence, environmental and world concerns. The potential gains and losses in the event where the UK contemplates new trade arrangements with the non‐EU countries are analysed in the Appendix .  相似文献
