据2011年河南省统计年鉴调查数据表明,河南省各地区农民支出差异较大,且呈现出进一步扩大的趋势。文章从河南省农民消费支出地区差异的现状着手,对河南省农民消费支出地区差异进行实证分析,找出影响河南省各地区农民消费支出的主要影响因素,并提出解决河南省农民消费支出差异较大问题方案的模型,为合理调整河南省农民消费结构,尽快消除消费支出地区差异较大并继续扩大的现象,实现各地区经济均衡发展提供一定的科学依据。 相似文献

In our 2011 survey of the literature in the Journal of Economic Surveys on the effect of government size on economic growth in wealthy countries we find a relatively consistent pattern: An increase in government size by 10 percentage points is associated with a 0.5–1 percentage point lower annual growth rate. This conclusion is questioned by Colombier. In this rejoinder we present a rebuttal of Colombier's argument based on a detailed scrutiny of his own statistical evidence and regression results. Furthermore, we note that several new papers that have appeared since our original paper was published give support to our main conclusion. 相似文献

This problem involves optimizing product collection and redistribution from production locations to a set of processing plants over a planning horizon. This horizon consists of several days, and the collection-redistribution is performed on a repeating daily basis. A single routing plan must be prepared for the whole horizon, taking into account the seasonal variations in the supply. We model the problem using a sequence of periods, each corresponding to a season. We propose an adaptive large-neighborhood search with several specifically designed operators and features. The results show the excellent performance of the algorithm in terms of solution quality and computational efficiency. 相似文献

The objective of this paper is to determine the mediation between tourism contribution and economic growth in the Greater Mekong Sub-region (GMS) (i.e. Cambodia, Laos, Myanmar, Thailand and Vietnam). The sample period is semi-annual data from 1995 to 2013 and is also estimated by bootstrap panel cointegration, Panel Fully Modified Ordinary Least Squares method and the Sobel test. The results show that the variables are cointegrated as three models; economic growth is running to tourism's total contribution to GDP and international tourism expenditure for passenger transport whereas international tourism expenditure for passenger transport is running to tourism's total contribution to GDP. Therefore, this study finds that international tourism expenditure for passenger transport is a mediator and has partial mediation. The GMS needs to develop every economic sector and improve the potential of the transport sector as a regional integration project which supports the sustainable development of the region. 相似文献

Using a large hand‐collected sample of all blockholders (ownership ≥ 5%) of S&P 1500 firms for the years 2002–2009, we first document significant individual blockholder effects on earnings management (accrual‐based earnings management, real earnings management, and restatements). This association is driven primarily by these large shareholders influencing rather than selecting firms’ financial reporting practices. Second, the market's reaction to earnings announcements suggests that investors recognize the heterogeneity in blockholders’ influence on earnings management. The results highlight the highly individualized effects of blockholders and a mechanism through which shareholders impact reported earnings. 相似文献

Abstract The literature on the relationship between the size of government and economic growth is full of seemingly contradictory findings. This conflict is largely explained by variations in definitions and the countries studied. An alternative approach – of limiting the focus to studies of the relationship in rich countries, measuring government size as total taxes or total expenditure relative to GDP and relying on panel data estimations with variation over time – reveals a more consistent picture. The most recent studies find a significant negative correlation: an increase in government size by 10 percentage points is associated with a 0.5% to 1% lower annual growth rate. We discuss efforts to make sense of this correlation, and note several pitfalls involved in giving it a causal interpretation. Against this background, we discuss two explanations of why several countries with high taxes seem able to enjoy above average growth. One hypothesis is that countries with higher social trust levels are able to develop larger government sectors without harming the economy. Another explanation is that countries with large governments compensate for high taxes and spending by implementing market‐friendly policies in other areas. Both explanations are supported by ongoing research. 相似文献

在带来巨大经济效益和高速经济增长的同时,大企业的外部性问题因其大规模生产和消费对整个社会和自然环境造成了严重的负面影响。同时对外部性问题的监测手段和技术的不断提升,以及社会大众对外部性问题的强烈关注,迫使大企业在政府监管督促的基础上,应该发挥其主观能动性,积极将其外部性问题内化。 相似文献

An econometric model is developed and estimated for all brands of coffee sold at the retail level in four supermarkets in Columbus, Ohio. These brands are segmented into 24 categories, and the four stores are classified into two groups, inner-city and suburban, based on 2010 census tract data. Using estimated measures of price-sensitivity, these 24 categories are further segmented into four groups to help guide and clarify the discussion. Estimated results show different purchasing patterns and different levels of price-sensitivity for inner-city and suburban shoppers. Further, these purchasing patterns and levels of price-sensitivity suggest alternative marketing strategies for retailers. Private-label coffee brands are shown to be quite competitive with many national brands, and indeed private-label brands command a market share among inner-city shoppers that is more than double that for the nation (21.95% vs. 9%). 相似文献
