中国中长期煤炭需求预测

首先对中国煤炭需求与经济增长的关系进行验证,然后将工业化水平、城市化率等变量纳入煤炭需求协整模型,分析了经济增长、工业化水平、城市化率、煤炭价格、煤炭利用效率和能源替代效应对煤炭需求的影响,并预测了在3种经济增长速度(高、中、低)下2012—2030年中国的煤炭需求。结果显示:未来20年期间中国煤炭需求仍将持续增长;经济低速增长下中国煤炭需求的增幅远低于经济高速或中速增长下的增幅;在城市化和工业化进程中,煤炭消费总量将经历刚性高增长阶段;煤炭利用效率、煤炭价格和能源替代效应对煤炭需求有一定影响。     

Gender imbalance in China’s marriage migration: Quantitative evidence and policy implications

While gender-imbalanced marriage migration across borders and regions and its socioeconomic impacts have been widely reported in developing nations, this paper reports empirical findings based on data from China since 1980. China’s international marriages were characterized with more than 95% of brides from mainland China in the 1980s but the proportion has dropped gradually to around 60% in recent years. Analysis of China’s census data and a panel dataset from Shanghai suggests that proportionally more women migrated from relatively less-developed to more-developed regions through marriage and the variation in income across regions is the key factor behind the migration pattern. China’s gender-imbalanced marriage migration has caused problems such as male marriage squeeze in poor rural areas and “leftover women” in large cities like Shanghai. Policies for poverty reduction and more balanced economic development across regions are recommended for reducing such gender imbalance and the associated socioeconomic problems.     

中国品牌经济发展的地区差距与影响因素——基于Dagum基尼系数分解方法与中国品牌500强数据的实证研究

本文使用世界品牌实验室发布的2004-2011年中国品牌500强数据,采用Dagum(1997)的基尼系数方法测算了中国品牌经济发展的地区差距并进行了地区分解,对品牌经济发展地区差距的影响因素进行了实证研究。研究结论表明:总体上中国品牌经济呈现快速发展态势而地区差距在持续扩大。具体而言,中国品牌经济发展的地区差距主要来源于超变密度和地区内差距的贡献,地区间差距虽呈上升趋势但其贡献相对较小。进一步地,动态面板数据的两步法系统GMM估计表明,一个区域内的品牌经济发展存在显著的循环累积效应,市场容量、区位条件对于品牌经济发展具有显著的正向促进作用,而R&D和市场竞争程度对于品牌经济的发展作用因被解释变量的不同而不同,而且在统计上也并不显著。     

我国区域收入差距与经济增长关系的实证研究——基于东、中、西部面板数据的协整分析

坚持区域经济协调发展,逐步缩小地区间发展差距,是提高经济落后地区居民收入水平、缩小同发达地区居民收入差距的一项长期战略。改革开放以来,从整体上说,我国各省区居民的收入和生活水平都得到了很大提高,但是由于各种原因,地区间经济发展的差距不仅存在而且有不断扩大的趋势。对我国东、中、西部地区居民收入差距与经济增长之间的关系进行研究分析,比较了三个地区居民收入差距的现状与变动趋势,分析了影响居民收入差距的主要因素以及这些因素对经济增长的影响,研究了收入差距与经济增长之间所存在的关系。     

Are costs really sticky and biased? Evidence from manufacturing listed companies in China

Recent studies on cost behaviour have proved that cost increase caused by business expansion is larger than cost decrease caused by business downsizing. This cost stickiness behaviour contradicts the traditional theoretic assumption that cost level and business size change in a linear way. This article investigates the existence or non-existence of cost stickiness using a sample of China’s manufacturing listed companies during the period 2010–2014. First, our findings show that cost stickiness is a pervasive phenomenon and overestimated in the manufacturing industry. Second, we find that cost stickiness varies greatly across industries and in different regions. Finally, we find that cost stickiness is affected by the economic growth. Specifically, cost stickiness increases with the macroeconomic growth. Our results from China’s manufacturing listed companies provide evidence on asymmetric cost behaviour and contain important implications for both cost accounting research and financial accounting research.     

金融发展与全要素生产率增长:区域差异重要吗?——来自中国省级面板数据的经验证据

基于1997-2008年中国省级面板数据以及分全国层面、沿海地区与内陆地区三个样本对金融发展与全要素生产率增长的联系及其中间渠道重新进行检验,结果发现:中国金融发展的全要素生产率增长效应与区域因素有关;中国金融发展促进全要素生产率增长的中间渠道是技术进步效应而非技术效率增长效应。这意味着,加快中国金融体系改革,从而推动金融发展对于经济增长质量的提高是非常重要的。     

技术进步、结构变迁与中国铁路运输业生产率增长——基于Hicks-Moorsteen生产率指数的实证分析

利用具有完全可乘性的非参数Hi cks-Moorst een生产率指数,对中国铁路运输业在1 997-201 0年期间的全要素生产率进行测算和分解,并对区域铁路运输业生产率进行绝对收敛检验。研究发现,平稳快速的技术进步是样本期间内中国铁路运输业全要素生产率快速增长的主要原因,而投入产出混合效率的下降则是各时段某些地区综合效率下降的重要因素;全国及三大地区的铁路运输业生产率在统计上均存在着显著的绝对收敛。此外,还应用面板计量模型实证检验了结构变迁、资本深化和引致需求等诸多因素对于铁路运输业全要素生产率、技术进步以及效率变动的相关影响。研究发现,产业经济结构和铁路运输内部结构分别与铁路运输业生产率之间存在显著的正相关和负相关关系;资本深化程度则呈现出显著的负向影响;各种引致需求因素和铁路路网密度均呈现出显著的正向影响;国有铁路所占比例与公路设施等替代竞争因素则均呈现出不同程度的负相关影响。     

Can China’s meat imports be sustainable? A case study of mad cow disease

Rising demand and constrained domestic production have challenged the meat consumption in China. To fill the gap between domestic demand and supply, China imports an increasing volume of meat products from the international market. However, outbreaks of animal diseases can jeopardize China’s ability to meet its need for consumable meat. This article investigates the impact of animal disease outbreaks on the sustainability of China’s meat imports by using the episode of bovine spongiform encephalopathy in the United States in 2003 as a case study. Our results show that China’s meat imports are becoming more diversified and sustainable. The outbreak did have significant negative impacts on beef imports from the United States. During the epidemic, not only was China able to increase beef imports from other major exporters, but it also increased imports of other animal products such as edible offal and pork. Our findings indicate that international trade can serve as a reliable source to meet China’s soaring meat consumption.     

创新型增长视角下的金融发展：综述及展望

传统经济增长理论分析框架下,金融系统只影响资本形成,并不创造社会财富,它对经济增长的作用只有水平效应而没有增长效应。新增长理论,尤其是熊彼特增长理论．突破了新古典增长理论关于技术进步的外生性假设,强调资本积累和创新是促进技术进步和经济增长的重要力量,这为研究金融体系对技术进步和经济增长的促进作用提供了全新视角。当前,中国金融发展现状与创新型增长要求之间存在一定程度的不相容性,需要在制度、政策和监管体系上不断完善与变革,逐步实现科技创新和金融发展的良性互动。     

India’s petroleum demand: estimations and projections

Energy security is crucial for sustaining high economic growth in India. This article empirically estimates India’s long- and short-term demand relations for crude oil, diesel and petrol (gasoline) using the ARDL and ECM cointegration procedures and then uses them to project demand for these products up to 2025 under various scenarios of GDP growth and oil prices. Our projections show that over 2012 to 2025, demand is likely to increase by about 74% for crude oil, 117% for diesel and 136% for petrol – the annual growth rates being about 4.3% for crude oil, 6.1% for diesel and 6.8% for petrol (gasoline). This article suggests that India needs to (1) take measures to improve efficiency in the use of petroleum products; (2) try to enhance supplies such as through production sharing agreements by Indian oil companies with other countries and (3) increase the use of nuclear, hydro, solar and other alternative energy sources, as Western European countries have done.     

我国物流业全要素生产率及其影响因素分析

运用索洛残值法测算了1997—2010年我国31个省(自治区、直辖市)的物流业TFP,构建空间计量模型,对物流业TFP的影响因素进行实证分析。研究结果表明:我国各省的物流业TFP具有明显的空间相关性和空间异质性;地理环境因素对物流业TFP的影响显著,地理位置相邻地区的物流业TFP具有趋同现象;基础设施和工业化进程对物流业TPF的提高有显著的正向影响,而市场需求条件和市场化水平的促进作用不显著。     

Multivariate filter estimation and ARDL model analysis of China’s potential output

In this article, we apply a new multivariate filter approach to estimate China’s potential output. Furthermore, we build an ARDL model to analyse the influence on potential growth caused by important factors that contribute to estimation and China’s development. Our results show that the current economic slowdown is not a cyclical phenomenon and China’s potential growth has declined since 2010. We also show that fixed asset investment and trade, which have a long-run relationship with potential output, exert negative long-run effect on potential growth justifying the implementation of China’s recent supply-side reforms.     

What Implications Does COVID-19 Have on Sustainable Economic Development in the Medium and Long Terms?

Given the enormous impact that the COVID-19 pandemic had on China’s economy, helping companies to revitalize post-pandemic economic activities promptly is a priority for the whole society. This necessitates the smooth circulation of production-factors among different economic entities, departments, and regions. The pandemic’s huge impact on the economy is evident in the severely hampered flow of these factors, including labor, materials, and capital. Therefore, using data and digital technology, combined with a contact-free allocation of labor, capital, and materials, to accelerate the flow of production-factors is critical to the post-pandemic economy’s restoration. Such a policy can not only provide a short-term stimulus but also a momentum for China’s mid- and long-term sustainable economic development.     

人民币汇率双向波动对中国及世界经济的影响--基于单一国家和多国的动态 CGE 模型

随着人民币国际化进程的加快,人民币汇率波动的国际效应进一步加强。文章分别建立了单一国家和多国的动态 CGE 模型,基于最新的全球贸易分析计划(GTAP )数据库和中国2012年投入产出表,分别模拟了2016－2030年人民币持续贬值和先贬值后升值的两种情景,并从物价水平、国际贸易、经济总量、行业产出等多个方面分析了人民币汇率变动对中国及世界主要经济体的影响。研究发现：(1)在价格指数方面,人民币贬值将给中国带来一定的通货膨胀压力;(2)在贸易方面,人民币贬值只能在短期内扩大中国的净出口,但在远期反而会导致净出口下降;(3)在经济总量方面,人民币贬值只在开始阶段的短期内能促进中国经济增长,而长期贬值将导致中国经济增长速度放缓;(4)在产业结构方面,中国的农业和工业在贬值情景下的产量呈现先升后降的趋势,而服务业的产量持续下降。总之,两种情景均不利于中国经济的长远发展;相反,东盟、日本和美国等世界主要经济体将从中长期受益。因此,中国政府应当制定若干针对性的政策措施,加强预期管理,实施差别化的外贸政策,加强多方合作,积极应对国际汇率波动带来的风险。     

我国区域经济增长收敛的计量分析

本文利用区域面板数据,对1979--2006年我国区域经济增长的收敛性进行了计量分析。研究结果表明,改革开放以来我国区域经济增长不存在绝对收敛趋势,但东、中、西部三大经济带基本上存在收敛趋势,形成了所谓的“收敛俱乐部”现象;在条件收敛回归中,如果控制了投资率、人力资本水平、非国有化水平、对外开放度、基础设施水平和产业结构等经济变量,我国区域经济增长则呈现显著的条件收敛。     

The impacts of China on economic growth: Evidence for Brazil,Chile, and Peru

This study empirically analyzes the direct impacts derived from the swift increase in exports to China (referred to as “the impact of China”) on the economic growth of three selected South American countries, Brazil, Chile, and Peru, during the commodity boom between 2001 and 2008. The results stemming from the balance-of-payments-constrained growth model suggest that the magnitude of China’s impact was less than 1 percent, although it ranged from the largest to the second largest impact among all trading partners for the three countries. The estimated balance-of-payments growth rate of domestic income is lower than the real growth rate of domestic income. This is because the growth rates of the export volumes were not sufficient even during the commodity boom, on account of the continued increasing trends of income elasticity of demand for imports. Furthermore, the income elasticities of demand for imports from China were especially high. Therefore, the three countries will continue to face further increase in the income elasticity of demand for imports as well as a stagnant growth rate of export volumes. Thus, the balance-of-payments position will continue to be the main growth constraint for these countries.     

Chinese Economy under the New "Dual Circulation" Strategy: Challenges and Opportunities—A Summary of the Annual SUFE Macroeconomic Report (2020–2021)

Entering year 2020, the Chinese economy was struck by the COVID-19 outbreak. The unprecedented pandemic, entangled with the already elevated complexities in the nation’s internal environment and external surroundings, aggravated its economic outlook. Internal factors including severe education mismatch in China’s labor force, its vanishing demographic dividend, the declined purchasing power of its middle-income groups, risen leverage ratio of households and enterprises, and soared local government debt reinforced to weaken China’s domestic demand. External factors, especially uncertainty in the China-US relation in the face of the re-shaping global value chain, dragged world economic recovery and thus China’s exports and imports. This summary report highlights some major challenges and opportunities faced by the nation under its new development strategy that stresses internal circulation of domestic economy aided by its interaction with the globe. Our analyses based on IAR-CMM model provide a unified framework for addressing China’s short-, medium-, and long-term issues in an internally coherent manner. Looking into year 2021, our benchmark projection reports an 8.4% annual real GDP growth rate. Alternative scenario analyses and policy simulations are conducted to assess the impacts of potential downside risks and the corresponding policy options for ensuring implicit targets. Through the lens of these analyses, we conclude that a refocus on effective management of internal demand, while deepening structural reforms on supply side and advancing orderly opening up, can help smooth the internal and external circulations of the Chinese economy to achieve high-quality development.     

中国经济规模报酬测算及影响因素分析

中国经济要保持长期持续增长必须要转变经济增长方式。经济增长方式由要素投入增加型转向效率提高型的经济学内涵在于报酬递增机制的形成。从这样一个视角出发,运用了35个工业行业2000-2008年数据对中国经济增长中的规模报酬情况进行了测算,并对中国报酬递增的影响因素进行了分析,发现现阶段分工与技术创新仍是最为核心的要素。中国经济增长方式要转向报酬递增驱动的机制,最为根本的在于分工与技术创新良性互动机制的形成。     

全球化时代的中国经济及其世界性影响

全球化进程决定了中国经济的高度开放,造就了双重资本积累模式,即内资主导的工业化城市化积累和外资主导的全球低端制造平台积累.这一模式加速了中国经济增长,同时削弱了经济自主.反过来,中国对世界经济造成了多方面影响,包括改变劳资利益格局,推动各国产业重组,改变金融市场结构,加强中美金融依赖等,这些影响随着中国的经济增长和结构升级将日趋显著.因此,中国必须立足内需实现可持续增长,并依靠技术创新来控制资源和环境成本.     

对外开放、基础设施规模与经济增长

本文采用主成分分析法构建了一个综合考虑国际贸易和FDI因素的对外开放指标和综合考察4类基础设施的基础设施规模指标。在此基础上利用中国28个省份1995—2008年的面板数据,以工具变量两阶段最小二乘法(2SLS)研究基础设施规模、对外开放与省区经济增长之间的关系,并检验了基础设施规模是否提高了对外开放对省区经济增长的促进作用。本文的实证结果表明:对外开放和基础设施规模都显著地促进了省区经济增长,对外开放和基础设施规模每提高1%,将导致人均实际GDP提高0.379%和0.251%;基础设施规模提高了对外开放对省区经济增长的促进作用,在基础设施相对发达的地区,其对外开放对省区经济增长的偏效应明显地高于基础设施相对落后的地区;最后从动态过程看,对外开放对各省区经济增长的边际影响都有不同程度提高,而基础设施规模对省区经济增长的边际影响在部分地区出现下降。
