中国绿色经济发展和机制政策创新研究

通过绿色转型创造新的发展和就业机会对于摆脱经济危机、提升国家竞争力并占据全球制高点和领先地位已经成为全球共识。中国的绿色经济发展将对其未来经济繁荣乃至全球经济发展产生深远影响。转变经济发展方式,实现绿色发展,这不仅是中华民族长远发展的战略性选择和必然需要,也是对全球可持续发展的积极贡献,将对人类发展产生的重要影响。中国正逐步走向绿色发展之路,建设资源节约型社会和环境友好型社会,发展循环经济和低碳经济已经为中国的绿色发展奠定了较为坚实的基础。但是在全球化大背景下,中国正面临各种规模庞大、情况复杂的经济发展、社会转变与环境保护的挑战与机遇,尤其是在宏观层面,绿色发展的体制机制保障尚不健全,制约了中国绿色转型的成效。如何通过恰当的制度创新,进一步推进转型成本效率的提高和体制机制与政策法规质量的改善,加快并深化中国的绿色转型是目前面临的主要问题。本文针对上述问题,系统归纳总结了国际上发展绿色经济的普遍经验以及中国发展绿色经济面临的主要问题和挑战,认为发展绿色经济目前并没有一种通用的模式,解决中国发展绿色经济发展过程中所面临的资源环境制约,必须调整现行以GDP为导向的政府和官员绩效考核体系,平衡目前财政分权体系中财权和事权不对应问题,进一步明确政府和市场的作用及各自起作用的领域,同时,综合应用法律、财政、税收和价格等工具,重视不同手段的综合和协同运用,在不同的发展领域,提出具有适应性和包容性的发展策略,具体来说:①实施"差异化"区域绿色发展战略,针对不同的经济发展和资源环境基础,提出不同的发展重点,同时,建立分区域的绿色发展监测和评估体系;②通过技术进步和管理创新发展绿色农业,以保障农产品安全、生态安全和资源安全为重点,推动农业发展政策、农业生产组织、农业技术服务和农业管理体系的转型;③以资源节约和环境友好为基本原则,实施绿色创新战略,引导和推动工业结构的优化升级;④创建绿色服务业体系;⑤推行绿色消费模式,以绿色消费倒逼绿色经济转型。     

包容性增长中人的全面发展的评价

本文系统地阐述了理论界对人的发展评价指标体系的不同观点,并基于现有包容性增长观的理论基础,根据经济增长对人的包容的评价维度,综合考虑了人的经济发展环境、人的社会发展环境、人的生态环境、人口素质和人的生活质量五大要素来构建指标体系。通过上述5个方面30个指标,基于因子分析法建立人的全面发展综合评价模型,对我国2004-2009年的人的全面发展情况进行评价。研究结果表明:我国2004-2009年人的全面发展状况呈现逐年上升的趋势,且增幅也逐年递增,这表明随着人的全面发展的速度加快,人的全面发展状况越来越好。结合主成分分析解析获得人的全面发展的两个主因子,分别为外部因子(25个指标)与内部因子(5个指标),两个子因子的累积方差贡献率达到87.890%,其中外部因子的贡献率为76.202%,内部因子的贡献率为11.688%。这说明,在决定人的全面发展水平的诸多因素中,外部要素和内部要素是两大主要因素,且前者的影响力大于后者。分析外部因子与内部因子的年际变化规律可知外部要素是正面因素,起着积极的作用,而内部因素则不然。说明我国人的发展存在以外延发展为主,内涵发展不足的现象。综上,文章针对内涵发展不足提出政策建议,以期通过关注人的生活质量、发展潜能和幸福指数,最终来实现人的全面发展。     

Dynamics of growth and seed production in the Siberian stone pine: The level and pattern of variation in characters

A statistical analysis of interannual variation in a set of vegetative and generative characters over 13 years has been performed to characterize the growth and seed production dynamics of the Siberian stone pine (Pinus sibirica Du Tour) in the southeast of the forest zone in western Siberia. The results have shown that the range of fluctuations in most of vegetative characters is ordinary and their distribution is close to normal. The range of fluctuations in many generative characters is enormous (from 0 to +∞), and the distribution of their values is usually skewed, with low values being recorded several times more frequently than high values. Most variable are the proportion of abortive cones and other characters that are determined mainly in the spring of the pollination year. These characters account for a very high level of variation in the total seed production.     

Will progress in science and technology avert or accelerate global collapse? A critical analysis and policy recommendations

Industrial society will move towards collapse if its total environmental impact (I), expressed either in terms of energy and materials use or in terms of pollution, increases with time, i.e., dI/dt > 0. The traditional interpretation of the I = PAT equation reflects the optimistic belief that technological innovation, particularly improvements in eco-efficiency, will significantly reduce the technology (T) factor, and thereby result in a corresponding decline in impact (I). Unfortunately, this interpretation of the I = PAT equation ignores the effects of technological change on the other two factors: population (P) and per capita affluence (A). A more heuristic formulation of this equation is I = P(T)·A(T)·T in which the dependence of P and A on T is apparent. From historical evidence, it is clear that technological revolutions (tool-making, agricultural, and industrial) have been the primary driving forces behind successive population explosions, and that modern communication and transportation technologies have been employed to transform a large proportion of the world’s inhabitants into consumers of material- and energy-intensive products and services. In addition, factor analysis from neoclassical growth theory and the rebound effect provide evidence that science and technology have played a key role in contributing to rising living standards. While technological change has thus contributed to significant increases in both P and A, it has at the same time brought about considerable eco-efficiency improvements. Unfortunately, reductions in the T-factor have generally not been sufficiently rapid to compensate for the simultaneous increases in both P and A. As a result, total impact, in terms of energy production, mineral extraction, land-use and CO₂ emissions, has in most cases increased with time, indicating that industrial society is nevertheless moving towards collapse. The belief that continued and even accelerated scientific research and technological innovation will automatically result in sustainability and avert collapse is at best mistaken. Innovations in science and technology will be necessary but alone will be insufficient for sustainability. Consequently, what is most needed are specific policies designed to decrease total impact, such as (a) halting population growth via effective population stabilization plans and better access to birth control methods, (b) reducing total matter-energy throughput and pollution by removing perverse subsidies, imposing regulations that limit waste discharges and the depletion of non-renewable resources, and implementing ecological tax reform, and (c) moving towards a steady-state economy in which per-capita affluence is stabilized at lower levels by replacing wasteful conspicuous material consumption with social alternatives known to enhance subjective well-being. While science and technology must play an important role in the implementation of these policies, none will be enacted without a fundamental change in society’s dominant values of growth and exploitation. Thus, value change is the most important prerequisite for avoiding global collapse.

Overcoming Contradictions Between Growth and Sustainability:Institutional Innovation in the BRICS

The recent accelerated growth rates or efforts to emulate countries that have achieved a rapid pace of economic growth are widely acclaimed as means to uplift millions from poverty. In so doing, however, this rapid economic growth is most likely to coincide with unsustainable levels of consumption, place excessive pressure on life support systems and terrestrial sinks and foreshorten options for the future. Rather than pursuing the Environmental Kuznets Curve (EKC) hypothesis that higher income will bring with it the means to reduce the impacts of greater consumption, ecological economists assert that buying our way out of future scarcity with fast growth is indeed contradictory with sustainability. To better understand these contradictions and explore potential institutional innovations that may enable developing nations to better confront them (in effect, tunneling under the EKC), this article refers to recent experience in the BRICS countries (Brazil, Russia, India, China and South Africa). Beginning with a brief comparative summary of major development and environmental indicators, pressures on resources and society in each of the BRICS are discussed, followed by identification of institutional and policy frameworks each country has evolved to confront the challenges of growth and sustainability. The article closes with general conclusions for further research and information sharing among developing nations.     

Combined influence of food level and inoculation density on competition between <Emphasis Type="Italic">Anuraeopsis fissa</Emphasis> and <Emphasis Type="Italic">Brachionus patulus</Emphasis> or <Emphasis Type="Italic">Brachionus macracanthus</Emphasis> (Rotifera: Brachionidae)

We tested separately the effect of two taxonomically related rotifers (B. patulus and B. macracanthus) on the population dynamics of another species (A. fissa) at low (0.5 ×10 ⁶) and high food levels (1.5 × 10⁶ cells/ml of Chlorella vulgaris) using different inoculation densities (0–100%). We also quantified the impact of A. fissa on the two brachionid species. Regardless of the presence of the competing species, an increase in the availability of food led to increase in the abundances of the three rotifers. The population growth of B. patulus, B. macracanthus, or A. fissa was affected negatively when cultured together with another species. An increase in the initial density of any one of the competing species became advantageous to maintain a certain population size. At a low algal food level, B. patulus was able to suppress A. fissa more strongly than B. macracanthus. On the other hand, at a high food level, B. macracanthus suppressed the population of A. fissa more strongly than B. patulus. Peak population densities for A. fissa varied from about 150 to 1000 ind./ml, depending on food density and the presence of competitors. The rate of population increase (r) of A. fissa, B. patulus, and B. macracanthus increased with an increase in food availability but decreased with increasing initial density of the competitor. Both Brachionus spp. experienced negative growth rates in the presence of A. fissa, especially at a high initial density of the latter.

Specific features of the growth of Scots pine vegetative organs in the forest-steppe zone of Cisbaikalia

The dependence of the annual increment of vegetative organs on air temperature and humidity and the amount of precipitation per phenophase, as well as the period of their growth in Scots pine, were studied in the forest-steppe zone of Cisbaikalia. The multiple effect of variation in environmental conditions on the annual increment of organs increased when precipitation in September of the previous year was taken into account. These factors proved to have a stronger effect on variation in the annual increment of needles (R ² = 0.59, p = 0.00005) than that in the annual ring width (R ² = 0.38, p = 0.0002).     

Evaluating the role of environmental quality in the sustainable rural economic development of England

The issue of the sustainable development of rural economies in England has recently received considerable attention. This is because many of the poorest areas in the country are rural, often of high environmental quality, but suffering from high unemployment and a lack of services and facilities. The rapid decline in agricultural incomes and in-migration of affluent urban workers since 1990 has exacerbated economic inequality in such areas. A number of factors have the potential to drive rural development and this paper applies, and considers, the feasibility of a method from the USA for combining economic and environmental variables in a regional growth model to examine the hypothesis that environmental quality is an important determinant of sustainable rural development in England. The model output suggests that, although environmental quality does play a role in sustainable rural development in England there are other, more important, factors driving development. These include business and communications infra-structure, the degree and opportunities for commuting and underlying employment prospects. The robustness and limitations of the method for combining economic and environmental variables is discussed in relation to the spatial interrelatedness of Local Authority Districts in England, and conclusions are drawn about areas for refinement and improvement of the method.

为了有效的把国家可再生能源规划分阶段的落实到各个省市,做好二者之间衔接工作,研究考虑了我国在从发展中国家过渡到中等发达国家时所需要考虑的如何平衡公平与效率之阀关系的问题,结合中国可再生能源发展实际特征,提出一种基于行业增长曲线的可再生能源阶段目标分解模型.模型首先求解出中国不同的可再生能源行业的增长曲线.然后给出可再生能源发展阶段目标函数.结合区域发展规划,给出了各省的阶段目标,为了验证该模型的正确性,以风电、水电和太阳发电为代表能源,结合国家可再生能源整体规划和资源需求分布状况,分阶段提出了各省域的可再生能源发展目标.目标分解参照两个原则(1)可分解原则.国家总量目标可以根据一定的标准在不同地区、部门和行业进行分解,由全社会共同完成发展目标.(2)公平性和区域差异的原则.考虑资源禀赋和社会经济发展水平差距,各地总量目标有所区别.研究对于可再生能源规划的整体实施和监管具有一定的借鉴意义.     

协调中国环境污染与经济增长冲突的路径研究——基于环境退化成本的分析

选取我国1990-2009年相关数据,首先对环境遥化成本进行估计,发现我国环境退化成本呈现不断上升的趋势,而水污染、空气污染是导致环境退化成本产生的主要原因.其次,以环境退化成本作为污染指标,结合环境库兹涅茨曲线的特征,并以能否有效地将污染指标降低到相对较低的水平,作为政策路径选择的标准,分析协调我国环境污染与经济增长冲突的路径.实证研究结果表明:在不考虑政策因素的影响下,我国目前国内生产总值水平仍处在环境库兹涅茨曲线拐点的左端,经济持续增长有可能导致环境状况进一步恶化;多项环境治理政策的同步实施,致使个别政策出现低效率甚至是无效率;在当前产出水平条件下,既要保证经济平稳增长,又要降低环境退化成本,政策路径的选择首先应注重产业结构的调整,适当保持第二产业比重,但在发展第三产业的过程中,应加大对污染企业的监管与治理,其次是调整国际贸易进出口比例,积极扩大出口,而采用吸引外商直接投资与加大污染治理投资等政策在我国现阶段均不能有效降低环境退化成本.
