重庆市城市用地供需状况研究

首先从供给数量和供给质量两方面,分析了重庆市区城市建设用地的供给状况。耕地在重庆市城市建设用地的供给来源中占有重要地位,但供给数量有限;受重庆市区自然条件的限制,城市建设用地的质量较差,表现在坡地多、平地少,冲沟多、地块小,难建地多、宜建地少,所以,重庆市城市建设用地的供给能力相当有限。其次,分析了重庆市区城市建设用地的需求状况。从城市GDP的增长、重点建设项目和城市人均用地水平的提高这三个方面分析了城市建设用地的未来需求趋势。结论是：重庆城市建设用地的供给相当有限,而需求量很大;随着未来重庆市经济社会的发展,城市用地的供需矛盾将成为城市发展中面临的一个重大问题。从合理利用和保护土地资源,为重庆的经济发展提供用地支持和保障的角度出发,文章就此问题提出了对策和建议。     

科技投入超效率测度的偏DEA分析与资本驱动的区域协调

现有科技活动效率研究存在异质性缺陷，导致无法深入分析引发效率差异的区域演进成因。应用超效率测度理论结合偏DEA视窗法，实证分析2010—2019年全国内地30个省（市）科技活动效率的动态演化进程，并从科技资本投入视角构建面板数据方程，考察不同资本类型驱动下我国科技投入效率空间溢出的直接效应与间接效应，同时，应用Moran′sI指数衡量各省（市）科技活动效率与空间集聚关联性。研究表明：近十年来我国科技活动效率整体呈现快速上升—趋势减缓—明显下降的发展态势，其中，东北地区效率饱和，投资冗余明显；华北地区效率偏低，高效率省（市）带动能力突出；华东和中南地区效率呈螺旋式上升，区域内省（市）组团差异明显；西北地区与西南地区效率偏高，但省（市）分化差异明显。从整体看，我国科技活动效率溢出能力显著，政府资本与企业资本对总效率溢出呈正向影响；外来资本对总效率溢出无明显影响，且资本效应的空间关联性不显著，绝大多数省市的科技活动效率提升处于资本弥补阶段，极少省市处于资本驱动状态。     

The U-shape of happiness in Scotland

We examine well-being in Scotland using micro data from the Scottish Health Survey and the UK Annual Population Surveys. We find evidence of a midlife nadir or zenith in Scotland in well-being at around age 50 using a variety of measures of both happiness and unhappiness. We confirm that higher consumption of fruit and vegetables is associated with higher levels of happiness in Scotland. We compare this with evidence for England from the Health Survey of England. The decline in well-being between youth and midlife is comparable in size to the loss of a spouse or of a job and around half of the fall in well-being in the COVID-19 lockdown. We also find a midlife peak in suicides in Scotland. Despite higher mortality and suicide rates in Scotland than in England, paradoxically we find that the Scots are happier than the English. Northern Ireland is the happiest of the four home countries. We also find evidence of U-shapes in England, Wales and Northern Ireland in the mid to late forties.     

WHY GROWTH RATES DIFFER—A SUMMARY AND APPRAISAL

This review article initially summarizes some of the highlights of the volume Why Growth Rates Differ , including the use of income shares as weights for the various factor inputs and some of the major factual conclusions drawn from the inter-country comparisons. Some of the main factors in differences in income levels and differences in growth rates are then reviewed.
In appraising the contribution of the volume, the monumental task is emphasized. This study illustrates the adaptability of the approach which Denison developed initially in The Sources of Economic Growth. The volume meets many of the questions and criticisms raised of his earlier study, and should encourage a shift of the discussion from methodology towards the substance of the empirical results.
The volume introduces some shifts in emphasis on the importance of different factors in growth. The role of demand variations and the contribution of capital is considered, but the evidence in the volume gives less emphasis on the importance of these factors than earlier work by others in both the United States and Europe. The volume gives some emphasis to shifts out of agriculture and the self-employed in the high postwar growth in many individual European countries. It considers the effects of reductions in trade barriers, and follows the view of most economists in playing this down. Advances in knowledge are also considered.
Those who are interested in questions of economic growth, past and future, and economic policy in this area will find much in this volume for study and reflection.     

风景名胜区时空关系演变分析

以中国近40年来国家级风景名胜区的发展历程，以及全国9批共244处国家级风景名胜区为案例，从理论层面探讨国家级风景名胜区时空格局的演变特征。结果表明：我国风景名胜区以自然文化遗产资源保护为根本，以“自然和人文交融”为特色；不同地区、不同批次的国家级风景名胜区呈现不同的空间分布特征，数量上东多南少，面积上西阔东疏，与中国历史上的“基本经济区”有重要的空间对应关系。进而提出了我国国家级风景名胜区布局的优化方向。     

我国东中西部地区产业创新、技术创新与组织创新协调性研究

将创新划分为产业创新、技术创新与组织创新3种类型,构建了产业创新、技术创新与组织创新评价指标体系,比较我国东、中、西部地区的3类创新发展水平,并测度了产业创新、技术创新与组织创新之间的匹配协调程度。研究结果表明：2008-2013年间我国东部地区创新发展水平明显高于中西部地区;东部地区创新之间的协调作用程度主要处于初级协调阶段,而中西部地区创新之间的协调作用程度处于濒临失调或勉强协调阶段,东部地区创新间的协调发展水平明显高于中西部地区。各地区在实施创新驱动战略中,应重视产业创新、技术创新与组织创新之间的匹配性与协调性。     

长江三角洲都市圈老人乡村休闲养老研究

近年来,长江三角洲都市圈越来越多的老人选择季节性移居乡村休闲养老,这种发展趋势是老龄化程度不断加深、城市养老资源不足和乡村休闲旅游快速发展共同作用的结果。通过对两个乡村休闲养老目的地的调查研究,结果表明：休闲养老目的地的形成可以分为在乡村旅游发展基础上的自发模式和企业投资促成的“联众模式”两种;乡村休闲养老者群体主要是低龄老人,选择乡村休闲养老目的地时主要受目的地自然环境、人文环境、休闲养老配套设施、生活基础设施、管理服务和目的地形象等因素的影响。季节性移居乡村休闲养老不仅可以缓解老龄化背景下都市圈不断增大的养老压力,而且可以解决乡村休闲旅游设施淡季的闲置问题,推动乡村环境的改善,促进当地村民的就业致富和城乡文明的交融与传播。都市圈具备条件的乡村可以把满足周边城市乡村休闲养老需求作为未来经济转型发展的一个方向。     

Biodiversity conservation, loss of natural capital and interest rates

It is argued that there is neither regular relationship between changes in the level of the market rate of interest and variations in the rate of biodiversity loss nor does such a regular relationship occur between alterations in the market rate of interest and changes in the rate of natural resource extraction. However, some texts suggest otherwise. Microeconomic examples are given in which a rise in the market rate of interest results in increased biodiversity loss and others in which it does not. It is also posited that the rate of biodiversity loss (as well as the rate of natural resource extraction) tends to rise with the level of aggregate investment and aggregate economic activity. It is demonstrated, using macroeconomic models, that the market rate of interest can increase or decrease with a rise in aggregate investment and also with an increase in the level of aggregate economic activity. Therefore, changes in biodiversity loss (and in the rate of natural resource extraction) are independent of variations in the market rate of interest in macroeconomic models.     

房价上涨挤压了我国企业的出口能量吗？

房价过快上涨会对整个社会经济带来全方位的影响。学术界和政府决策者虽然都已经认识到了房价上涨对生产性投资、企业创新、企业家行为和企业融资的影响,但对房价上涨与企业出口之间的内在关联却没有加以足够重视。那么,房价上涨与企业出口表现之间的关系又如何呢？文章利用35个大中城市的出口企业数据,运用 Heckman两阶段模型估计房价上涨对企业出口表现的影响。结果发现：（1）房价上涨增加了企业出口数量,但不利于出口产品种类的增加、技术复杂度的提升以及出口市场的拓展,总体上降低了企业出口金额;（2）房价上涨对不同类型企业具有异质性影响,其对中小企业、民营企业和加工贸易企业的负面影响更为突出;（3）房价上涨影响企业出口的内在机制是,房价上涨通过影响企业用工成本、融资约束、研发投入和劳动力流动性挤压了企业的出口能量。文章为我们更加全面地认识房价上涨的社会影响提供了启示,也为政府应对当下的企业出口困境提供了借鉴。     

中国建筑园林的南北差异

我国建筑和园林南北差异明显。在园林方面,南巢北穴,缘由不同;南敞北实,形式不同;南水北石,要素不同;南花北柏,植被不同;南私北皇,社会背景不同。在宗教建筑方面,南方多佛教名山和道教洞天福地,北方多佛教石窟。此外,在民居的空间布局和建筑形式方面、街坊格局方面,也有差异。建筑和园林的南北差异是我国地域文化景观的重要组成部分。     

The evolution of post-communist systems

I propose in this article a new interpretation of the evolution of post-communist systems by comparing the evolutions in Central and Eastern Europe and in China. Transition is reinterpreted as the result of a collapse of communist state structures in Central and Eastern Europe and, in China, in contrast, as the result of the will to prevent such an outcome. This reconceptualization helps us to better understand the emergence of bad institutions and corruption in Eastern Europe under the market economy as well as the absence of political liberalization in China and the strengthening of the power of the Communist Party in recent years.     

基于研究联合体的国家自主创新示范区企业转型升级评价——2016-2020年1 827家上市公司的实证分析

作为引领区域创新发展的前沿阵地,国家自主创新示范区企业必须率先实现高质量转型升级,以支撑示范区充分发挥其创新引领和辐射带动作用。基于扎根理论,对11个典型案例进行研究,得到具体影响因素,在此基础上构建研究联合体视角下国家自主创新示范区企业转型升级评价指标体系,并运用AHP-熵权组合赋权模型对2016-2020年中国1827家A股制造企业进行实证研究。结果发现：示范区企业转型升级综合指数整体较低,企业转型升级水平具有较大提升空间;东中西部示范区企业转型升级水平存在较大差距且呈现扩大趋势;南北部示范区企业转型升级不存在显著差异,制造业为主的南部示范区企业转型升级水平较高;示范区企业转型升级受研发创新协同的影响较大,后者是示范区企业转型升级的主要影响因素。鉴于此,国家层面应健全以政府为主导的示范区企业支持政策体系;示范区层面应积极落实国家重大区域发展战略,以培育高精尖人才科研团队、搭建智能化研究联合体为发力点;企业层面以示范区企业研究联合体作为新引擎,聚焦示范区企业核心技术难题,促进示范区企业高质量创新发展。     

中国国际分工地位的再评估?--基于出口技术复杂度与国内增加值双重视角的分析

合理地评估当前中国的国际分工地位是判断中国的出口优势与劣势以及提升中国的国际分工地位的重要依据。文章将出口技术复杂度和国内增加值率结合起来,构建了同时具有产品属性和增加值属性的国际分工地位新指标,并基于投入产出框架构建了理解国际分工地位差异的理论模型,进而对中国的国际分工地位进行了再评估。结果表明：(1)考虑服务业出口后,目前中国的国际分工地位处于最为落后的经济体行列,亚洲新兴经济体的国际分工地位普遍不高,发达经济体和资源丰富的经济体拥有较高的国际分工地位。(2)1995-2009年中国与美国、印度和巴西之间的分工地位差距有所扩大,与德国之间的分工地位差距比较稳定,而与日本之间的分工地位差距则有所缩小。(3)结构分解的分析显示,中国国际分工地位落后的主要原因是出口结构问题,即服务业出口比重过低,而国内增加值率的降低也在发挥越来越重要的影响。(4)中国国际分工地位指数的变动主要源于产业属性效应和国内增加值效应,而出口结构效应的影响则较低。因此,调整出口结构和提升国内增加值率是中国未来提升国际分工地位的两种重要方式。     

FACTORS IN CANADA-UNITED STATES REAL INCOME DIFFERENCES

This paper is a part of a larger study of economic growth in Canada, following the methods developed by Edward Denison in his book The Sources of Economic Growth in the United States and the publication Why Growth Rates Differ. The new material in this paper relates to Canada and the Canadian/U.S. comparison, while the material on Northwest Europe is drawn from the Brookings study. The present paper sets out the results to date on the differences in real output per employed person between Canada and the United States for one year, 1960. At this stage in our research the results indicate that the level of real output per employed person in Canada was about 20 per cent lower than in the United States in that year. On the basis of historical output data, it would appear that this margin of difference in Canadian/U.S. product levels has persisted throughout the present century. The central part of this paper examines the significance of differences in factor inputs in Canada and the United States and their contribution to the difference in income. The level of inputs per employed person in Canada accounts for only about 2 percentage points of the income difference between Canada and the United States. These results indicate that the overwhelming part of the difference in output per employed person between the two countries reflects the differences in output in relation to total factor inputs, rather than the magnitude of other factor inputs used in combination with labour. This result is consistent with earlier studies by Denison and others which have indicated the crucial importance of output in relation to total factor inputs, both in output growth over time and intercountry comparisons of output level. The body of the paper can give only brief attention to the numerous conceptual and statistical questions that arise in such a wide-ranging study, and the authors do not pretend to have tackled, let alone resolved, all of the wide range of problems related to this study. Nor do they claim any high degree of precision for the results, especially in the light of the statistical limitations of the basic data.     

CYCLICAL FLUCTUATIONS IN FACTOR SHARES AND THE SIZE DISTRIBUTION OF INCOME

The way in which cyclical fluctuations in activity in the U.K. economy affect factor income shares and the channels through which these effects work through to the size distribution of income are traced. Using National Accounts data, the impact of an upturn in activity in increasing the shares of profits and self-employment income in factor incomes, and of self-employment and rent, interest and dividends in personal incomes, is quantified. Using Family Expenditure Survey micro-data, the resulting shift in decile shares in personal income, which is towards the top of the size distribution, is estimated.     

Productivity change in Canadian mining 1957–1979

This paper calculates multifactor productivity trends in seven Canadian mining industries and relates changes in productivity to various factors, including changes in output and factor prices and the decline in the quality of the ore being mined. It is found that productivity decline in mining has been pronounced and tended to predate that of manufacturing by several years. There are indications that the most important factors in the decline have been the fall in mineral grade, contraction of output, increases in interest rates and an apparent decline in the rate of technical innovation.     

加工贸易活动成效差异原因探究——基于东亚与拉美的经验

台湾地区、韩国加工装配活动成功和智利、阿根廷成效差异的原因,在于发展战略、政策环境、劳动力市场发育程度与外部环境差异等等;东亚由加工装配活动成功向加工贸易活动转变,而东南亚成效不佳的原因,在于后向联系和技术溢出方面的差异;中国大陆的加工装配活动是成功的,已在增加就业、增加国民收入与缩小收入差距、平衡国际收支和技术转移方面发挥了积极作用,沿海地区加工装配产业在比较优势将消失的趋势下,向中部地区转移这些产业并同时实现产业升级将是最优选择.     

Nonperforming Loans and Purchase of Loans by Public Asset Management Companies in Malaysia and Thailand

This paper explores the factors which eliminated the nonperforming loan (NPL) problem in Malaysia and Thailand following the 1997 Asian financial crisis. The number of NPL, which expanded in the aftermath of the crisis, has since declined in most South‐East Asian countries. Although previous studies have explored the causes of the increase in NPL numbers, few have analysed the factors that contributed to the reduction in their number in Asia. In Malaysia and Thailand, authorities put in place several measures to manage NPL. As a vehicle to acquire NPL from banks, Malaysia established the Pengurusan Danaharta Nasional Berhad (Danaharta) in 1998, while Thailand established the Thai Asset Management Corporation (TAMC) in 2001. We analyse whether the characteristic features of banks, improvements in macroeconomic conditions, and facilities for purchasing loans caused a reduction in the number of NPL in Malaysia and Thailand. The results suggest that selling loans to a public asset management company was effective in reducing the number of NPL in Thailand. While macroeconomic conditions influenced the decline in NPL ratios in Thailand, in Malaysia, well performing commercial banks and large commercial and investment banks generally had smaller NPL ratios throughout and following the crisis.     

The role of consumption patterns,demand and technological factors on the recent evolution of CO2 emissions in a group of advanced economies

Changes in production structures and modifications of patterns of consumption are key factors in the fight against environmental harm. Initiatives such as Agenda 21, promoted by the UN, highlight the need to evaluate the relationships among factors of production and consumption, innovation and demographics, and the environment, in the attainment of sustainable development. In this context, our work studies in depth those factors underlying the economic activity of households, in a representative group of European Union countries and the US. Within the framework of an input–output model, a Structural Decomposition Analysis is considered in order to identify the weight that growth in demand, changes in patterns of consumption, changes in the distribution of income, the substitution of inputs, and changes in energy intensity have all had on the evolution of CO₂ emissions. The work specifically seeks to identify common patterns and differential behaviors among productive sectors in the European social environment. The results show that growth in demand, and therefore in production, largely absorbs the limited effect of technological and efficiency improvements and the incipient changes observed in consumption patterns.
