1地理集聚、行业集中与中国企业出口模式的差异性显示文摘基于2000~2006年间持续经营的47000多家制造业企业数据,本文经验考察了外资参与、地理集聚与出口外溢对我国企业出口模式选择的影响。将全部企业划分为非出口、持续出口、新增出口以及间断出口四种不同类型,本文借鉴显性比较优势(RCA)思想构造了区域内与区域间、产业内与产业间外溢指标。多项式分布logit模型的估计结果表明,外资进入不仅显著地促进了企业自身的出口可能性,而且还通过对内资企业的出口外溢效应形成了企业出口的地理扩散与行业集聚效果。但与盛行的“本地化外溢”假说相反,我们发现出口外溢效果并未表现出随地理距离缩小而更为强烈的本地化现象,即局部地区的大量同质性出口企业过度集聚导致了我国企业出口外溢的“去本地化”效应,而且这一结果在控制了外溢指标的可能相关性、外资来源地以及企业所有制之后仍然稳健。包群 邵敏 Ligang Song 2012管理世界2012,28,9:33
2Motion behavior of particles in air-solid magnetically stabilized fluidized beds for separation显示文摘In order to study the settling mechanism of particles in an air-solid magnetically stabilized fluidized bed(MSFB) for separation,we carried out free settling and quasi-zero settling tests on the tracing particles.The results show that the main resistance forces as the tracing particles settled in an air-solid MSFB were motion resistance force and yield force.The motion resistance and yield forces greatly hindered the free settling of the particles by greatly decreasing the acceleration for settling process of the particles.The acceleration decreased from 3022.62 cm/s 2 to zero in 0.1 s,and in the end,the particles stopped in the air-solid MSFB.The yield force on particles increased with increasing the magnetic field intensity,resulting in decrease of the quasi-zero settling displacement.However,the yield force on particles decreased with increasing the fluidized air velocity,leading to increase of the quasi-zero settling displacement.When the structure and operating parameters of the air-solid MSFB were set up,the yield stress on particles stopped in an air-solid MSFB was a function of diameter and density of particles.The settling displacements of equal diameter particles increased with increasing their densities,and the settling displacements of equal density particles increased with increasing their diameters.Song Shulei a,,Zhao Yuemin a,Luo Zhenfu a,Tang Ligang b a School of Chemical Engineering and Technology,China University of Mining & Technology,Xuzhou 221116,China b Coal Mining and Designing Department,Tiandi Science & Technology Company Co.Ltd.,Beijing 100013,China 2012International Journal of Mining Science and Technology2012,22,5:13
3State-owned Enterprises' Outward Investment and the Structural Reform in China显示文摘自从中国在 2001 的 WTO 的就职,中国以从事向外直接的投资在一条陡峭的学习曲线上,并且国有企业(SOEs ) 在这个运动起了一个占优势的作用。我们主张根据它国内改革上的影响被担心,由 SOEs 海外的那项投资是一把双重的剑。投资海外提议机会在中国,而是如此的投资加深结构的改革能也加强一些 SOEs 的垄断位置,它与国内改革的目的不一致。因此,中国关于竞争,所有权和规定加深国内改革是重要的,到从海外投资最大化好处。现在的纸也讨论大楼市场兼容机机构怎么将导致增加的革新。这提供机会让中国公司有效地赶上先进技术在海外市场仍然保持竞争。Ligang Song Jidong Yang Yongsheng Zhang 2011China & World Economy2011,19,4:13

6The COVID-19 Pandemic and Its Impact on the Global Economy: What Does It Take to Turn Crisis into Opportunity?显示文摘The COVID-19 pandemic broke out at a time when there were heightened uncertainties in the global economy.Understanding these uncertainties provides an important background for analyzing the impact of the pandemic on the global economy,assessing the effectiveness of policy measures in combating the pandemic and reviving the global economy,and predicting the trajectory of the economic recovery in the post-pandemic era.We analyze how COVID-19 would likely deepen an existing malaises in the global economy,and what could be done to address these problems while managing the economic recovery.We argue that three fundamental factors that could lead to a solid recovery in the post pandemic era are structural reform,new technology and re-integration.They could be managed by instituting a new'global social contract.'Supported by strong public policies at all levels,especially at national level,these three factors could bring about the salvation of the global economy as it recovers or re-emerges from the pandemic crisis.Ligang Song Yixiao Zhou 2020China & World Economy2020,28,4:9
7An overview of energy and metabolic regulation显示文摘The physiology and behaviors related to energy balance are monitored by the nervous and humoral systems. Because of the difficulty in treating diabetes and obesity, elucidating the energy balance mechanism and identifying critical targets for treatment are important research goals. Therefore, the purpose of this article is to describe energy regulation by the central nervous system(CNS) and peripheral humoral pathway. Homeostasis and rewarding are the basis of CNS regulation. Anorexigenic or orexigenic effects reflect the activities of the POMC/CART or NPY/AgRP neurons within the hypothalamus. Neurotransmitters have roles in food intake, and responsive brain nuclei have different functions related to food intake, glucose monitoring, reward processing. Peripheral gut-or adipose-derived hormones are the major source of peripheral humoral regulation systems. Nutrients or metabolites and gut microbiota affect metabolism via a discrete pathway. We also review the role of peripheral organs, the liver,adipose tissue, and skeletal muscle in peripheral regulation. We discuss these topics and how the body regulates metabolism.Song Wen Chaoxun Wang Min Gong Ligang Zhou 2019Science China(Life Sciences)2019,62,6:8
8A study of miRNAs targets prediction and experimental validation显示文摘microRNAs(miRNAs)are 20–24 nucleotide(nt)RNAs that regulate eukaryotic gene expression post-transcriptionally by the degradation or translational inhibition of their target messenger RNAs(mRNAs).To identify miRNA target genes will help a lot by understanding their biological functions.Sophisticated computational approaches for miRNA target prediction,and effective biological techniques for validating these targets now play a central role in elucidating their functions.Owing to the imperfect complementarity of animal miRNAs with their targets,it is difficult to judge the accuracy of the prediction.Complexity of regulation by miRNA-mediated targets at protein and mRNAs levels has made it more challenging to identify the targets.To date,only a few miRNAs targets are confirmed.In this article,we review the methods of miRNA target prediction and the experimental validation for their corresponding mRNA targets in animals.Yong Huang Quan Zou Haitai Song Fei Song Ligang Wang Guozheng Zhang Xingjia Shen 2010Protein & Cell2010,1,11:7
9International Financial Adjustment for China:A Financial Valuation Approach显示文摘International financial adjustment is the process whereby valuation shifts from asset price and currency changes result in relatively durable net wealth transfers across countries' international balance sheets.This paper applies a financial valuation approach to estimate the direction and the broad extent of recent international financial adjustments on China's international balance sheet.We estimate China's international balance sheet losses resulting from the valuation shifts over the period 2005-2010 and reveal that international currency shifts over the past decade have also generated a range of non-balance sheet financial and monetary adjustment pressures for China.This paper also evaluates how China's evolving international financial policy arrangements could better mitigate China's exposure to international financial adjustments.These arrangements include a more effective currency mechanism and the mechanisms to internationalize the RMB to buffer international financial valuation shocks.Luke Deer Ligang Song 2013China & World Economy2013,21,1:5
10Promoting Private Entrepreneurship for Deepening Market Reform in China: A Resource Allocation Perspective显示文摘在超过三十年快速的生长以后,中国的经济正在通过一个重要拐弯处点,在在供应和需求方面的结构的不平衡必须为一条更中等、持续的生长路径被探讨的地方。由集中于它的所有权的结构的变化,在中国在市场改革下面的经济转变的一个中央元素,现在的纸在以一条更有效、持续的路驾驶经济生长在加深市场改革并且,从而强调私人 entrepreneurship 的重要性。基于资源分配和 entrepreneurship 的一个概念的框架的一个观点,纸在所有权改革的上下文在私人部门和它的表演的进化上详细描述,与州的部门的表演做比较。分析建议为经济资源,特别首都,土地和自然资源的更高效的使用有进一步的空间,由增加在有赞成国有企业的高入口障碍的工业的私人企业家的参予。而且,通过改革的生产资源的更有竞争力、相等的存取被需要支持更高效的 entrepreneurship 并且减少寻求租金的活动。Son Ngoc Chu Ligang Song 2015China & World Economy2015,23,1:4
11A comparison between acute large vessel occlusion in the posterior circulation and anterior circulation after endovascular treatment:the ANGEL-ACT registry experience显示文摘Background and purpose Endovascular treatment(EVT)has shown an overwhelming benefit for acute anterior circulation artery occlusion(ACO).Whether it can achieve the same outcomes in posterior circulation artery occlusion(PCO)has not been well explained.We aimed to evaluate the characteristics and prognosis of ACO and PCO after EVT in a nationwide registry.Method The present analysis was based on the prospective ANGEL-ACT Registry in China between November 2017 and March 2019.Demographic data,periprocedural times,recanalisation rate,intracranial haemorrhage(ICH)and 90-day functional outcomes were compared between the ACO and PCO groups.Results A total of 1793 patients were analysed including 397(22.1%)consecutive patients with PCO and 1396(77.9%)patients with ACO treated with EVT.A larger proportion of patients with PCO had intracranial atherosclerotic disease and received extra angioplasty during EVT.Successful recanalisation and 90-day favourable functional outcomes did not differ significantly between the two groups.Patients with PCO showed lower 24-hour ICH and symptomatic ICH rates.There was a trend towards higher mortality rate in the PCO group(22.09%vs 14.44%;adjusted OR 1.286(95%CI 0.820 to 2.017),p=0.2731),especially when the onset to puncture time was over 6 hours(30.77%vs 11.13%;adjusted OR 2.673(95%CI 1.280 to 5.583),p=0.0089,interactive p=0.0002).Conclusions In this large prospective multicentre registry,there was a significant difference in the characteristics and periprocedural features between patients with PCO and ACO.However,successful recanalisation and 90-day favourable functional outcomes in PCO were equivalent to those in ACO.Xuan Sun Jingyu Zhang Xu Tong Baixue Jia Dapeng Mo Ning Ma Feng Gao Lian Liu Xiaochuan Huo Ligang Song Yiming Deng Zhongrong Miao 2022Stroke & Vascular Neurology2022,7,4:4
12China's Approach to Rebalancing:A Conceptual and Policy Framework显示文摘这篇文章寻求发展一概念并且为在全球经济不平衡理解中国的角色的政策框架。中国对经由周期性的贸易和金融剩余的这些不平衡的贡献与加深结构的风险到中国的经济生长和发展的一个阶段相应。这些结构的挑战包括:源于中国的动态内部转变,中国的贸易取向,资源使用的轨道和 CO2 排出物,关于分发的福利问题和国际限制的生长的作文。这篇文章为检验在长期间的过程之间的关系开发一个概念的框架在在处理这些结构的挑战的机构的改革的中国,它的经济不平衡,和角色的结构的转变。因此,经济政策应该在短期的宏管理以外延长追求一个机构的改革议程便于更宽广的结构的变化减轻限制到未来生长并且改进经济福利。Luke Deer Ligang Song 2012China & World Economy2012,20,1:4
13Staged angioplasty versus regular carotid artery stenting in patients with carotid artery stenosis at high risk of hyperperfusion:a randomised clinical trial显示文摘Background and purpose Hyperperfusion(HP)is a devastating complication associated with carotid artery stenting(CAS)or endarterectomy.The efficacy and safety of staged angioplasty(SAP)in patients with CAS at high risk of HP remains unclear.We sought to determine whether SAP is superior to regular CAS in patients with high risk of HP.Methods A randomised,multicentre open-label clinical trial with blinded outcome assessment(STEP)was conducted.Patients with severe carotid stenosis at high risk of HP were randomly assigned(1:1)to the SAP or regular CAS group.The primary endpoint was hyperperfusion syndrome(HPS)and intracerebral haemorrhage(ICH)within 30 days after the procedure.Results From November 2014 to January 2017,a total of 64 patients were enrolled in 11 centres.33 patients were allocated to the SAP group and 31 to the regular CAS group.At 30 days,the rate of primary endpoint was 0.0%(0/33)in the SAP group and 9.7%(3/31)in the regular CAS group(absolute risk reduction(ARR),9.7%;95%CI−20.1% to 0.7%;p=0.11).As one of the secondary endpoints,the incidence of HP phenomenon(HPP)was lower in the SAP group than the regular CAS group(0.0%vs 22.6%,ARR,−22.6%;95% CI−36.8%to−10.2%;p=0.04).Conclusion The rate of HPS and ICH was not significantly lower in SAP group;the extended secondary endpoint of HPP,however,significantly reduced,which suggested that SAP may be a safe and effective carotid revascularisation procedure to prevent HP.Dapeng Mo Baixue Jia Huaizhang Shi Yaxuan Sun Qingan Liu Chengzhe Fan Jianping Deng Jinglin Yuan Wei Wu Changchun Jiang Guilian Zhang Hanjun Du Ning Ma Feng Gao Xuan Sun Ligang Song Lian Liu Guangge Peng Yongjun Wang Yilong Wang Zhongrong Miao the STEP Study Group 2021Stroke & Vascular Neurology2021,6,1:3
