中国地区居民生活水平比较——基于全球夜间灯光数据

当衡量一国或地区居民生活水平时,统计学上一般有收入和消费两种视角。本文利用城乡住户调查中的人均可支配收入和国民经济核算中的居民消费水平,以全球夜间灯光数据为参照,综合收入端与消费端信息,对1997—2016年中国31个地区的真实生活水平进行比较分析。研究证实,灯光亮度与消费水平和人均可支配收入之间均存在显著的线性关系,可以用来估算真实生活水平。根据不同模型的回归结果得到,真实生活水平的最优无偏估计中消费水平的权重范围为（2795%,3831%）,人均可支配收入水平的权重范围为（6169%,7205%）。相对于消费水平,人均可支配收入更能准确地反映真实生活水平。本文进一步分析发现,样本期内居民生活水平增速小于人均GDP增速,可见经济的发展并未完全转化为生活水平的提高。中西部地区与东部地区的生活水平仍然存在巨大差距,东部地区的平均生活水平分别是中部和西部地区的17倍和21倍。     

家庭异质性视角下城乡居民家庭碳排放研究——以陕西为例

为把握城乡居民各种口径碳排放的变动趋势,借鉴IPCC推荐方法及投入产出分析方法,分别测算2005—2017年陕西省居民家庭各种口径的碳排放量,发现陕西城镇家庭各口径碳排放量均高于农村家庭;为分析引起城乡居民家庭直接和间接碳排放总量变动的深层原因,借鉴对数平均迪氏指数分解(LMDI)模型,发现家庭人均收入、家庭户数效应、家庭规模效应、能源消费结构、能源消费强度、家庭消费率、家庭消费结构等表征家庭异质性的变量对城乡家庭直接及间接碳排放总量有不同程度的正向驱动或负向驱动效应,并根据研究结论对地方政府控制家庭碳排放量提出政策建议。     

Migration and regional convergence in the European Union

We offer an empirical, econometric analysis of the impact of migration on the EU27’s NUTS2 regions in the period 2000–2007. We find that migration had no significant impact on regional unemployment in the EU, but affected both GDP per capita and productivity. A 1 percentage point increase in immigration to immigration regions increased GDP per capita by about 0.02?% and productivity by about 0.03?% on impact and by 0.44?% for GDP per capita and 0.20?% for productivity in the long run. For emigration regions an increase in the emigration rate leads to similar reductions of GDP per capita and productivity both on impact and in the long run. Since immigration regions are often regions with above average GDP, while emigration regions in Europe practically all have below average GDP, migration does not seem to promote convergence.     

Estimating Krugman’s Economic Geography Model for the Spanish Regions

This paper estimates Krugman’s (J Polit Econ 99:413–499, 1991) economic geography model using data from the Spanish NUTS 3 regions. The econometric formalization endogenously determines wages in a region as a function of income and wages in other regions. The specification adopted also allows us to study the relation between the agglomeration of economic activity, increasing returns and market access. The first result obtained is that the Spanish economy exhibits a spatial wage structure: wages in a region are positively determined by income and wages in neighboring regions. In second place it is found support for the structural relations of the underlying theoretical model, indicating the importance of scale economies and transport costs in shaping the Spanish economic geography.     

中国碳交易政策的减排效应及其机制研究

全球气候变暖对环境和经济发展影响巨大,碳排放是气候变暖的主要原因,碳交易政策是基于市场机制控制碳排放及推动绿色低碳发展的一项核心政策工具。采用2004—2019年中国30个省的面板数据（因数据缺失,未包含西藏地区和港澳台地区数据）,基于双重差分和中介效应模型对碳交易政策的减排效应及其作用机制进行了实证研究。研究结果表明,不论从总体看还是分区域看,碳交易政策均具有显著的减排效应,但效应的大小存在区域差异,碳交易政策在东部地区的减排效应比中西部地区更大。机制分析发现,碳交易政策可通过减少能源消耗规模、促进技术创新、促进产业结构升级、增加外商直接投资等渠道实现减排,能源规模、技术创新、产业结构、外商投资等在碳交易政策传导中具有显著的中介效应,但这种传导机制存在区域差异。     

河南省能源消费碳排放量演变及其与经济增长关系的研究

笔者计算了1978年~2009年河南省一次能源消耗的碳排放量。研究发现,1978年以来,河南省一次能源消耗的碳排放数量一直在增加。碳排放强度虽然逐渐下降,但人均碳足迹却不断上升,其中,煤炭消耗的碳排放量是总排放量的主要来源。河南省一次能源消耗的人均碳足迹与人均GDP的关系并不符合标准的环境库兹涅茨曲线,而是呈现出三次曲线关系,而碳排放强度与人均GDP之间呈则现出反比曲线关系。     

城镇化、城乡消费比例和结构对居民消费间接CO2排放的影响*

本文利用投入-产出分析法计算了我国居民消费间接CO2排放量,并应用结构分解分析（SDA）方法分析了城镇化、城乡消费比例、消费结构等因素对居民消费间接CO2排放的影响。研究结果发现：（1）城镇化的扩张和消费结构的升级是增加我国居民消费间接CO2排放的重要因素,尤其是食品、居住和交通通讯是导致居民消费间接CO2排放的主要部门;（2）城乡消费比例和排放强度对居民消费间接CO2排放具有明显的抑制作用;（3）人均消费的提高对居民消费间接CO2排放增长贡献最大。最后,本文基于实证结果提出了减少我国居民消费间接CO2排放的政策建议。     

Examining the influencing factors of CO2 emissions at city level via panel quantile regression: evidence from 102 Chinese cities

Ascertaining the influencing factors of carbon dioxide emissions in Chinese cities is an important issue for policy-makers. This paper investigates the effect of several determinants on carbon emissions per capita in Chinese cities. Non-normally distributed and heterogeneous features of carbon emissions per capita in Chinese cities are considerably important. The empirical results demonstrate that GDP per capita has an increasingly positive impact on carbon emissions per capita due to the growth in household consumption. Urbanization has a slightly decreasing positive effect on carbon emissions per capita with a quantile increase resulting from continuous highway construction. Industrialization has a decreasing positive effect with carbon emission per capita quantile increases because of increasing energy efficiency and lower costs related to carbon reductions. The population has a decreasing negative effect on carbon emissions because of people’s increasing demand for environmental safety. The distributions of emissions per capita conditional on the 10th and 90th quantiles of independent variables also vary considerably. Specific policy implications are provided based on these results.     

近20年来中国区域经济发展差异的测定与评价

选取人均GDP、人均社会消费零售总额社会经济指标,通过计算其变异系数、加权变异系数、威廉森系数、最大与最小系数,对中国1978-2002年的经济发展不平衡性进行了动态时序分析,定量评价,了近20年来中国区域社会经济发展的差异程度;采用经济区位酶指标分析了中国经济发展空间格局的动态演化过程。结果表明,1990年以前中国经济区域差异程度在减小,1990年以后经济区域差异程度扩大,社会消费水平总体上呈扩大趋势。在空间格局上,经济发达区由过去的东北地区扩展到东部沿海地区,1970-1980年代区域差异表现为经济发达区、经济发展区、经济落后区之间的差异,而到1990年代主要表现为经济发达区和经济落后区之间的差异,两极化趋势明显,区域差异程度加大。     

中国地区经济增长与能源消费强度差异分析

本文假设我国西部与东部地区的能源消费强度差异是西部与东部地区人均GDP差异的函数,然后同其他回归变量一起检验这两个变量之间的关系,并通过使用面板数据计量经济学模型进行实证估计。本文的研究结论为:第一,总体而言,西部与东部地区的人均GDP差异存在收敛,随着人均GDP的收敛,西部与东部地区的能源消费强度差异也是收敛的,但收敛的速度慢于人均GDP的收敛速度。第二,不同西部省份在经济增长过程中的能源使用效率是收敛还是发散存在差异。本文的政策含义是:政府在制定区域经济发展战略时,要鼓励和引导各地区充分利用能源禀赋以及能源利用效率方面的差异进行合作,走能源节约型的可持续的区域平衡增长道路。     

Linking Public Investment to Private Investment. The Case of Spanish Regions

Public investment constitutes one of the main instruments of regional policies. The existence of a direct link between infrastructure and regional income per capita is usually accepted. Literature also describes a positive effect of public investment on private capital accumulation. This paper seeks to provide new empirical evidence on this latter relationship for the case of Spanish regions over the period 1965–1997 using panel data methodology. The results show a positive effect of productive and social public investment (especially in education) on private investment. The spillover effects generated by the productive infrastructures located in other regions do not seem to encourage the private investment in neighbouring regions. Public consumption and interest rate exert a negative influence on private capital accumulation. These results are robust to changes in the econometric specification.     

Income distribution dynamics across European regions: Re-examining the role of space

This paper is aimed at exploring the role played by space on the dynamics of regional per capita income disparities in Europe between 1980 and 2005. To do that, an analysis based on the so-called distribution dynamics approach is used as benchmark. Therefore, the external shape of the per capita income distribution and movements within it are examined using both continuous and discrete techniques. This first approach reveals that regional disparities across European regions have decreased over time and, based on the computation of a mobility index, also highlights the existence of a medium mobility degree within the distribution. Subsequently, a spatially conditioned distribution dynamics approach is developed to adequately assess the spatial dimension of the convergence process. In this new approach per capita income of each region is doubly conditioned on its per capita income and the per capita income of its neighbours, both in a previous period. Additionally, a novel mobility index on the basis of a spatial Markov chains approach is devised. The results illustrate the importance of geography in explaining regional per capita income evolution; in particular it is shown that poor regions surrounded by rich regions have a much higher probability of escaping the poverty trap than other poor regions.     

A decomposition analysis of CO2 emissions in the United States

This article decomposes the growth in US CO₂ emissions by state. Using the Logarithmic Mean Divisia Index (LMDI) method, we account for CO₂ emissions change in each state between 1990 and 2004. The change is decomposed into five effects: (a) emissions per unit of fossil fuel; (b) share of fossil fuel in total energy consumption; (c) energy intensity; (d) gross state product per capita and (e) population. Results show that for the past 15 years gains in the efficiency of energy use in the economy, the lowering share of fossil fuels in total energy consumption and lowering of emissions intensity of fuels all contributed to offsetting the effect of Gross Domestic Product (GDP) per capita and the population growth in carbon emission across the US.     

Does diversity matter? A fresh inquiry into the energy,economy and environment nexus

ABSTRACT

The article extends the literature on the nexus among economy, environment and energy by incorporating an index of electricity generation diversity in production and emission functions. The index is mathematically equivalent to Herfindahl–Hirschman index. The index captures substantial information regarding the ongoing energy transition at the global level. The results obtained through pooled mean group estimation, on a dataset of fairly diversified group of countries, indicate that if diversity index increases by a percentage point, per capita income increases by 2.4% and per capita emissions are reduced by 0.71%. This is against the conventional wisdom in favour of specialization. The study has found some interesting long-run causal pathways. Firstly, the causality runs from diversification to income. Secondly, there is a causality running from electricity consumption to specialization. Thirdly, bi-directional causality runs between emissions and specialization. The results have interesting policy implications. The study supports the growth hypothesis that the electricity consumption drives the economy. As this inevitably increases emissions, a better pathway is through diversification. The fossil fuel intensive pathway may have been the preferred choice in the past for countries with low electricity consumption; the diversified portfolio appears to be prudent in the future.     

Catching Growth Determinants with the Adaptive Lasso

Abstract. This paper uses the adaptive Lasso estimator to determine variables important for economic growth. The adaptive Lasso estimator is a computationally very efficient procedure that simultaneously performs model selection and parameter estimation. The computational cost of this method is negligibly small compared with standard approaches in the growth regressions literature. We apply this method for a regional dataset for the European Union covering the 255 NUTS2 regions in the 27 member states over the period 1995–2005. The results suggest that initial GDP per capita (with an implied convergence speed of about 1.5% per annum), human capital (proxied by the shares of highly and medium educated in the working age population), structural labor market characteristics (the initial unemployment rate and the initial activity rate of the low educated) as well as being a capital region are important for economic growth.     

PUBLIC CAPITAL, PRODUCTIVE EFFICIENCY AND CONVERGENCE IN THE SPANISH REGIONS (1964–93)

This paper analyses the behaviour of productive efficiency in the Spanish regions for the period 1964–93. From a growth accounting approach, it describes the regional evolution of total factor productivity (TFP'), based on a private inputs production function. A stricter measure of efficiency is then quantified, which is not equivalent to Solow's residual, since public capital is included in the production function and constant returns to scale are not imposed. Finally, on the basis of the measures of total factor productivity and efficiency, the study discusses the existence of technological convergence among Spanish regions and the role played in it by public capital. The renewed interest in the analysis of the process of growth reflected in economic literature in recent years has also occurred in the case of the Spanish economy, with some peculiarities which are worth mentioning. In the 1980s, two important institutional changes took place: a profound political and administrative decentralization, the regions now being autonomous in many decisions on public expenditure, and the incorporation of Spain into the European Community, which as it is well known has a powerful regional policy. Both changes have meant that the analysis of regional economies, and especially their growth paths, have received much more attention from politicians and economists, and even from the population in general. In particular, intense discussion has taken place regarding the effects of development policies and on criteria for geographical distribution of infrastructures. In both cases, much attention has been paid to discussing their capacity to contribute to convergence among the different regions. As a consequence of this greater interest in the analysis of growth from a regional perspective, efforts have also been made to improve the relevant statistical information. In particular, statistical series have been drawn up for investment and accumulated capital stock in each region, both private and public.' This information, only recently available and the first of its kind, as far as we know, in the European regions, substantially broadens the possibilities of research into the Spanish case in this field, where before not even the simplest exercises in growth accounting could be attempted. Further-more, since the series now available allow the time dimension of growth analysis to be combined with the regional dimension, it is possible to work with a panel of data and apply the corresponding techniques. This article analyses the growth of the Spanish economy over the period 1964–93, during which it can be observed that the per capita income levels of the Spanish regions converged. The objective of the study is to evaluate this process of convergence in income from the perspective of the productive efficiency of the regions, in three different ways. First, Section I considers the importance of the contributions of the private factors of production and of improvements in total factor productivity to the growth of output. Secondly, section II studies the existing relationship between the standard measure of efficiency (Solow's residual or TFP') and a stricter measure when the endowments of public capital are considered. Section III analyses whether or not the convergence in per capita income

ESTIMATION OF THE STOCK OF CAPITAL IN SPAIN

The paper presents the methodology and results of the estimation of the endowments of capital in the Spanish economy. It distinguishes between endowments of public capital and private capital. The series corresponding to the public sector cover the period 1955–97 and consider seven categories (or functions). The estimates are disaggregated by 17 regions and 50 provinces. The level of disaggregation is regional and provincial (NUTS2 and NUTS3 in European terminology). The private capital series cover the period 1964–97 and consider 17 sectors of production, with disaggregation at regional level. The information refers to two variables: gross formation of fixed capital (in current and constant pesetas) and capital stock in constant pesetas (base year 1990).     

京津冀能源消费、碳排放与经济增长

运用《2006年IPCC国家温室气体清单指南》中的碳排放核算方法[1],测算2000—2011年京津冀二氧化碳排放量、排放强度、人均排放量和单位面积排放量,从变动趋势、消费结构、相关性和空间分布四个角度分析京津冀的能源消费、碳排放与经济增长。结果表明:京津冀能源消费量和碳排放量在12年间均呈增长趋势;碳排放强度均呈下降趋势;津冀的高排放主要是由以煤炭消费为主的能源结构和以高耗能工业为主的产业结构引起的。碳排放量与能源消费量和经济增长密切相关。在京津冀协同发展背景下,应大力调整产业结构,优化能源结构,建立碳汇合作机制。
