资本匹配、创新力培育与区域协调发展：理论机制与经验证据

区域协调发展不仅受到资本积累数量的影响，更受到资本匹配质量的制约。在拓展MRW模型的基础上，理论分析“实物资本-人力资本-社会资本”最优匹配存在性与高效经济增长的关系，进一步构建资本匹配程度与匹配质量通过创新力培育实现落后地区经济赶超，进而影响区域协调发展能力的传导路径，并利用中国省级面板数据进行实证检验。结果表明，实物资本、人力资本与社会资本存量之间存在最优比例关系，且资本匹配质量主要通过创新力培育影响区域协调发展水平；资本匹配整体上有利于区域协调发展，东部地区资本匹配度对区域协调发展的促进作用高于中部地区、西部地区；机制检验发现，资本匹配通过组织创新效应实现区域协调发展的解释程度最大，其次为技术创新效应，最后是产业创新效应。     

产业集聚、市场集中对区域创新能力的作用——基于京津冀、长三角两大经济圈制造业的比较

产业集聚和市场集中是影响区域创新能力的重要因素。本文考察了京津冀、长三角两大经济圈制造业产业集聚与市场集中对区域技术创新能力的作用。实证分析结果表明：两大经济圈制造业集聚与市场集中均在一定程度上促进了区域创新能力的提升，但由于两大区域体制机制条件、创新环境、产业组织形态等不同，制造业产业集聚影响区域技术创新的程度、特征与路径也存在一定差别。两大经济圈应采取差异化集群发展方式，加快推进制造业集群升级，特别是应抢抓第四次工业革命发展机遇，提升制造业智能化水平，提升区域创新能力水平。

Optimal allocation of direct and embodied arable land associated to urban economy: Understanding the options deriving from economic globalization

Land resources do not flow directly but can be allocated as “embodied land” in goods and services during economic globalization. The term “embodied arable land” can help link local land allocation strategies to the global and national supply chains and trade activities, and suggest new lens in optimizing arable land allocation. China is facing a serious arable land shortage, especially in municipal administrative areas. Based on the nested input-output analysis (Nested IOA), this work takes Shanghai as an example, exploring the allocation of direct and embodied arable land of an urban economy within the process of economic globalization. The amount of embodied arable land associated with Shanghai economy is 6.09 Mha, broken down into local arable land use (0.20 Mha), domestic inflows (3.20 Mha) and foreign inflows (2.69 Mha). This area supports local final demand (4.32 Mha), domestic outflows (1.24 Mha) and foreign outflows (0.53 Mha). Land-related imbalances emerge in the study, namely the economy’s demand versus the city’s size, the arable land demand versus supply, and embodied arable land inflows versus outflows. Regarding the role of the urban economy in allocation of global arable land under economic globalization, on the one hand, Shanghai has intensively involved with a large amount of embodied foreign arable land resources, and has been heavy dependent on foreign embodied arable land; On the other hand, there is still large potential for Shanghai to take the opportunity of economic globalization for an optimal allocation of direct and embodied arable land. Policy suggestions on taking the opportunity of economic globalization for an optimal allocation of direct and embodied arable land are put forward.     

Are betting returns a useful measure of accuracy in (sports) forecasting?

In an economic context, forecasting models are judged in terms not only of accuracy, but also of profitability. The present paper analyses the counterintuitive relationship between accuracy and profitability in probabilistic (sports) forecasts in relation to betting markets. By making use of theoretical considerations, a simulation model, and real-world datasets from three different sports, we demonstrate the possibility of systematically or randomly generating positive betting returns in the absence of a superior model accuracy. The results have methodological implications for sports forecasting and other domains related to betting markets. Betting returns should not be treated as a valid measure of model accuracy, even though they can be regarded as an adequate measure of profitability. Hence, an improved predictive performance might be achieved by carefully considering the roles of both accuracy and profitability when designing models, or, more specifically, when assessing the in-sample fit of data and evaluating out-of-sample forecasting performances.     

Shrinking Cities,Shrinking Households,or Both?

Household size decline accounts for a substantial portion of population loss in shrinking cities, yet little research has focused on it. Much of the literature presents a simple growth/decline binary that is largely determined via population figures. In this paper, we highlight the importance and assess the impact of household size changes on population decline, and determine what types of household size declines are more acute in shrinking cities than other locales. We find that elderly households and households with school-aged children are under-represented in shrinking cities, while households with pre-school-aged children are over-represented. More tellingly, we find the biggest source of household-related loss in shrinking cities to be the growth of single-person households now living in houses that were once home to entire families. These findings puncture the binary on which much of the shrinking cities discourse is based. The population dynamics of most cities are subtler than either practitioners or critical scholars assert. We argue that plans and development strategies for shrinking cities should reflect a range of demographic changes, including outmigration and internal household restructuring.     

Environmental taxes,reforms and economic growth: an empirical analysis of panel data

This paper explores the relationship between environmentally related taxes and the economic growth rate. The analysis also investigates whether this relationship differs between countries that have implemented environmental tax reforms (ETRs) and those that have not. Using panel data from 31 OECD countries over the period 1994–2013, the paper finds that when we allow environmentally related tax revenues to interact with an initial level of real GDP per capita, the overall revenues of these taxes are negatively associated with the economic growth rate in the short and long term. Furthermore, we show that the higher the initial level of GDP per capita, the more environmentally related tax revenues can promote the economic growth rate. The analysis also reveals that the relationship between environmentally related tax revenues and economic growth varies between countries that have a mechanism to redistribute environmentally related tax revenues and those that do not.     

Public spending,public governance and economic growth at the Vietnamese provincial level: A disaggregate analysis

This study examines the role of economic governance in the relationship between public spending, private investment, and economic growth in Vietnam at the provincial level. The study data consist of sixty-two Vietnamese provinces for the period 2006–2015. Some notable results are attained by applying a sequential (two-stage) estimation. First, the marginal benefits to economic growth of increased Vietnamese provincial government expenditures may be constrained because of the inefficiency of expenditures on education, business services, and public administration. Second, public spending and private investment are found to be substitutes at the provincial level. Third, based on the Provincial Competitiveness Index (PCI) ranking, used as a proxy for provincial public governance in Vietnam, the significance of public governance can be observed. The study concludes that good governance, characterized by different attributes, such as lower informal charges, greater transparency, and unbiased policy, plays a critical role in improving the impact of government expenditure on economic growth in Vietnamese provinces, particularly through its interactions with private sector investment.     

“一带一路”背景下人民币国际化的原油计价研究

在"一带一路"倡议下,人民币国际化的原油计价面临着重大机遇:中国与"一带一路"沿线能源出口国利益互补、亚洲缺少原油定价中心、全球出现"去美元化"的趋势以及人民币国际化具备强有力支撑等条件,但同时也面临着资本管制与原油期货市场流动性的冲突、较低开放度的中国金融市场无法为人民币提供畅通的回流路径以及"新特里芬难题"等挑战。借鉴相关发展经验,应积极推进人民币原油期货市场建设、推进金融市场开放构建人民币环流、扩大与"一带一路"沿线国家(地区)的贸易往来、借助基础设施建设强化人民币计价功能等,努力实现人民币国际化的原油计价。     

中国东北三省与“一带一路”沿线国家贸易格局时空演变

利用2003年~2017年东北三省与"一带一路"沿线国家进出口贸易数据,采用地理集中度、位序变动指数、综合贸易份额指数、HM指数分析东北三省与沿线国家贸易格局及特征的变化。结果表明:东北三省与"一带一路"沿线国家的贸易往来日益密切,贸易总额大幅增加,尽管东北三省与东北亚地区的贸易份额有所下降,但东北亚地区始终是东北三省的贸易重心。东北三省与沿线国家贸易依赖度不断提高,具有明显的不对称性,表现出显著的单向依赖。从进出口商品结构来看,东北三省向沿线国家出口的资源密集型和劳动密集型商品占比下降,技术密集型商品占比有较大提升,出口商品更加多元化,附加值和科技含量进一步提高,进口商品结构相对稳定,主要为资源密集型和技术密集型商品。
