中国共产党历来重视转变经济发展方式,转变经济发展方式是我们党长期推进经济发展战略过程中的明智选择,是适应国内外经济形势发展变化的客观需要,是遵循人类社会经济发展规律的必然要求,是我们党在市场经济条件下力求保持人与自然和谐发展的重要举措,既要清醒地认识到我国转变经济发展方式面临的深层次问题,又要积极探索转变经济发展方式中所面临问题的解决路径.改革开放以来,尽管我们在经济建设方面取得显著成效,但仍然存在许多亟待解决的问题,如经济发展速度过度依赖以牺牲环境为代价,经济发展动力过度依赖外贸进出口,经济发展方式过度依赖外资,经济发展效果评价过度依赖GDP指标等.为加快转变经济发展方式,必须做到四个坚持,即在经济发展理念上坚持以科学发展观为指导,在经济发展动力上坚持内需与外需并重,在经济发展方式上坚持以公有制为主体,在经济发展效果上坚持数量与质量相融合的综合评价. 相似文献

Using an in-depth longitudinal case study based on an “historical retrospective”, this article focuses on how some factors (“drivers”) set into motion the pendulum of change in supply structures, a research theme neglected in the supply field. It examines, over a 20-year period, the changes made to the supply structure of a well-known organization. The data comes mainly from: (a) semi-structured interviews with 21 managers and professionals within eight operating units, and (b) documentary analyses of the archives. This article shows how to map structural changes of the supply function, while explaining the nature and the causes of these changes. Understanding the pendulum movement from one supply structure to another can be very valuable, as well for academics as for managers. 相似文献

动态助词"过"一般分为"过1"和其中"过2","过1"表示动作的完结,"过2"表示曾然。其语法化历程为:一般动词"过"→趋向动词"过"→动态助词"过1"→动态助词"过2"。动态助词"过1"和"过2"的演变又可分别区分为两个阶段,即演变发生和演变扩散。就形成机制而言,"过1"的产生主要是受隐喻、类推以及重新分析的作用,趋向动词"过"的形成是"过1"产生的关键;而"过2"是"过1"吸收了助词"来"及其经常出现的句法环境的语法意义而产生的,可以说是"过1"在特殊语境下的产物。 相似文献

We investigate the relative impact of internal Delphi process factors - including panelists' degree of confidence, expertise, majority/minority positioning - and an external factor, richness of feedback - on opinion change and subsequent accuracy of judgmental forecasts. We found that panelists who had low confidence in their judgmental forecast and/or who were in a minority were more likely to change their opinion than those who were more confident and/or in a majority. The addition of rationales, or reasons, to the numeric feedback had little impact upon panelists' final forecasts, despite the quality of panelists' rationales being significantly positively correlated with accurate forecasts and thus of potential use to aid forecast improvement over Delphi rounds. Rather, the effect of rationales was similar to that of confidence: to pull panelists towards the majority opinion regardless of its correctness. We conclude that majority opinion is the strongest influence on panelists' opinion change in both the ‘standard’ Delphi, and Delphi-with-reasons. We make some suggestions for improved variants of the Delphi-with-reasons technique that should help reduce majority influence and thereby permit reasoned arguments to exert their proper pull on opinion change, resulting in forecast accuracy improvements over Delphi rounds. 相似文献

Analyses were carried out on financial compensation to avoid loss of tropical forests and related carbon (C) emissions when marginal financial yield declined for land-use options with extended areas, and when a risk-averting perspective (modeled according to financial theory around the capital asset pricing model) is assumed. The approach in this study was to consider natural forest, forest plantation, pasture, and cropland simultaneously to investigate how an optimized land-use distribution may reduce the amount of compensation necessary to avoid C emissions from forest loss.The financial compensations derived were as high as US$ 176 per hectare per year when comparing natural forests only with the most profitable alternative (croplands). However, compensation decreased to US$ 124 for risk-neutral decision-makers, who would strive for optimized land-use allocation, and to only US$ 47 per hectare per year for risk-avoiders, who would look to maximize the reward-to-variability ratio. Sensitivity analyses indicated that the compensation under risk-aversion increased much less than under risk-ignoring when increased productivity of agricultural land-use or growing demand for agricultural products was simulated. It was concluded that considering appropriate diversification strategies and the well documented human behavior to avoid risks is an important step in developing cost-effective compensation policies. 相似文献

In this paper, we adopt a recent OECD framework and examine the role of external policy tools and internal firm specific factors for stimulating three different types of eco-innovations that range on a spectrum of lower to higher technological and environmental impacts: End-of-Pipeline Pollution Control Technologies, Integrated Cleaner Production Technologies and Environmental R&D. Using a novel firm-level dataset from a DEFRA survey, we estimate a Tobit model, which provides empirical evidence showing that these eco-innovations are motivated by different external policy tools and internal firm specific factors. Our findings indicate that End of Pipeline Technologies and Integrated Cleaner Production Technologies are mainly driven by equipment upgrade motives with a view of improving efficiency while environmental regulations are effective in stimulating the End-of-Pipeline technologies and Environmental R&D. Interestingly, alongside government induced regulations, we find that market factors, mainly motivated by cost savings, are effective in driving Environmental R&D. Finally, ISO14001 certification is effective in strengthening the positive impact of environmental management systems on both End-of-Pipeline technologies and Environmental R&D while CSR policies have no significant impact on motivating any of the eco-innovations. 相似文献

江苏粮食生产地域分化的耕地因素分解 总被引:5,自引:1,他引:4
以粮食产量计算模型为基础,将粮食生产分解成耕地利用的数量、结构、强度、广度4个因子.以江苏省为例,从省域-分区域-地市等不同空间尺度,分析粮食生产的耕地因子过程,比较各地粮食生产变化的差异及其耕地利用变化的成因.结果显示:1990年代中期以来,江苏粮食生产区域分化显著,南部耕地大幅减少、有限耕地的生产功能减退,导致粮食生产全面萎缩;中北部耕地利用集约度提升,粮食生产功能总体趋于强化.影响各地市粮食生产变化的主导因子各有不同:粮食单产是连云港、盐城、宿迁、扬州、泰州5市粮食增产的主导因子,结构调整是南京、徐州、南通粮食减产、淮安粮食增产的主导因素;复种指数调减是苏州、无锡粮食生产衰退的首要因子. 相似文献
