休闲产业:国内研究述评

休闲产业研究在我国尚处于起步阶段。目前国内对休闲产业的研究主要集中于休闲产业的概念和范围、休闲产业的地位和作用、休闲消费、影响我国休闲产业发展的主要障碍和对策等几个方面,今后研究的重点应转向建立休闲产业统计体系、揭示休闲产业和消费结构的变化规律、检验休闲产业的就业功能及其与建设和谐社会的关系上来,在研究方法上应注重从定性分析转向定量分析。     

核心企业集约的多产品、多级供应链库存控制策略研究

在供应链环境及结构稳定情况下,供应链上的各节点企业,根据需求来调整相应的运作策略。基于多层供应商及供货产品为多品种且集约到一个核心企业的供应链网络,根据该供应链网络供需结构和特点分析了各节点的需求特征,得出了订货提前期为随机条件下的最佳库存费用,并利用各节点服务水平约束下的临界值及库存费用凸函数特性确定了供应链的运作策略。

试论扩大民间消费与经济的发展——基于农村消费市场的分析

长期以来,我国的经济发展在很大程度上靠出口拉动,对国民经济增长贡献率最低的是消费。2008年金融危机以来,我国的贸易出口增速下降、顺差缩小、产品出口受到严重影响。拉动经济必须扩大消费,我国农村市场需求广大,对拉动消费及发展经济有重要的作用。

The Role of Water in Manufacturing

Water's role in manufacturing technologies has received limited attention. A KLEM model of the sector's technology is extended to include two facets of water use: intake and recirculation. Three annual cross-sectional surveys on plant-level water use are pooled and combined with census data to estimate this extended model for the Canadian manufacturing sector over the period 1981–1991. While Canada's water allocation regulations influence private water withdrawals, statistical tests support representing water intake as a variable input. Water intake is found to be a substitute for water recirculation, energy, labour and capital. The relationship between water intake and recirculation is stronger when water intake is process-related rather than related to cooling and steam production. Technological change has been biased in the direction of increased water intake and decreased water recirculation.     

西部地区农户收入水平对农村能源消费的影响分析

西部地区农村人口众多,农村能源建设是西部地区可持续发展的一个重要条件,而沼气建设是西部农村能源建设的重点。文章在介绍西部地区农村能源概况的基础上,对农户收入水平对沼气消费的影响进行理论、实证分析,得出农户人均纯收入水平对农村人均沼气消费量的影响是非线性关系的结论,提出针对不同收入水平的农户采取相应的措施来解决农村能源短缺,促进生态农业良性发展。

The proposed framework outperforms state-of-the-art univariate models in the time series forecasting literature. It has achieved 17th position in the accuracy track of the M5 forecasting competition, which is among the top 1% of solutions.     

政府支出与私人消费的关系研究——基于跨国数据(1983-2008年)的面板协整分析

文章运用面板协整分析方法和世界上36个国家(20个发达国家和16个发展中国家)1983-2008年的面板数据进行跨国研究,通过建立变系数面板模型并结合可支配收入和宏观经济环境的影响,分析了政府支出和私人消费的关系。研究结果显示,总体上而言,样本国家的政府消费支出与私人消费成互补关系,可支配收入仍然是影响私人消费的主要因素,宏观经济环境(经济开放程度和失业率)对消费的影响在统计上很不显著。为了扩大消费,中国政府应实施积极的财政政策、扩大财政支出和提高社会保障水平以及切实解决民生基本难题。     

The effect of copayments on primary care utilization: results from a quasi-experiment

This article analyses how health-care utilization is affected by copayments in a tax-financed health-care system. The article utilizes a natural experiment in which a health-care region in Sweden changed the price of healthcare in such a way that primary care general physician prices increased by 33%. We use daily visit data in the treatment region and a neighbouring control region where no price change took place and analyse the effect using differences-in-differences as well as differences-in-differences-in-differences models. The results from the preferred models indicate no effect on health-care utilization due to the price change, a result that also holds across different socio-economic subregions in the treatment region.
