为破解我国在高技术产业全球价值链中面临的低端锁定困境,需要构建并完善国家价值链分工体系。构建中国高技术产业国家价值链内生增值传导网络结构分析框架,并以电子信息产业为例,对省域国内增加值进行分解。结果表明,现阶段中国电子信息产业上游技术研发能力较弱,整体增值能力不强;下游间接关联产业部门数量及关联系数值仍待提高;除中游外,上下游出口国内增加值偏低,国际竞争力较弱;东、中部省域国内完全增加值占据优势,内生增值能力方面各有所长,东北、西部省域国内完全增加值及其内生增值能力均较弱。同时,中国省域国际垂直专业化程度未表现出显著地理地区特征,即使同一地域的省域之间也存在不同程度差异。 相似文献

本文基于中国227家商业银行2005-2016年非平衡面板数据,实证检验中国宏观审慎政策实施对于银行风险承担的影响。结果表明:宏观审慎政策增强会在一定程度上抑制银行风险承担,而且这种显著的负向关系并不随着银行风险代理变量、经营辐射范围以及是否有外资入股等条件的改变而发生变化。经济周期会对宏观审慎政策的有效性产生非对称性影响,即相比在经济上行时期,在经济下行时期的宏观审慎政策对银行风险承担的抑制作用更强且更为显著。就可能的影响机制而言,本文发现宏观审慎政策通过提高银行盈利能力,从而降低银行风险承担。

Due to the serious increase of environmental pollution in China, environmental regulations have become significantly stringent. Such regulations are playing an increasingly important role in the development of small enterprises (SEs) in China, especially in SEs' market entry. However, existing studies pay little attention to this issue. This paper investigates for the first time the effect of environmental regulations on SEs' market entry and the mechanism of environmental regulation effects in China. We consider two sets of panel data for the periods 2003–2010 and 2012–2015 in China. We also use the fixed effect model and the instrumental variable method to explore the role of environmental regulations in SEs' market entry. The results show that, overall, environmental regulations play a significantly positive and robust role in SEs' market entry. However, the mechanisms associated with the effect of environmental regulations on different innovative types of SEs differ. Environmental regulations promote the market entry of SEs with product innovation, but this impact is not significant for SEs with research and development (R&D) activities and R&D institutions. Our findings indicate that China's SEs prefer product innovation, which is a lower level innovative type, over R&D innovation, as a means to avoid the negative impact of stringent environmental regulations. 相似文献

We investigates the sentiment-driven trading behaviour of the four types of investors in the London office market, i.e. UK institutional investors, UK private investors, UK listed real estate companies/Real Estate Investment Trust (REIT)s and overseas investors. In addition, we examine the relationship between investor sentiment and property performance. Related indices are calculated to examine the existence of herding behaviour of different investors. We find that UK private investors follow a contrarian strategy to UK institutional investors and listed real estate companies/REITs and enter/exit the market at different points of time. UK institutional investors tend to follow the sentiment of UK listed real estate companies/REITs and overseas investors with lags. There is no evidence that overseas investors rely upon the sentiment of UK specialised property investors in their decision-making. We find the sentiment of different investors is influenced differently by market fundamentals. Yield and rental growth rate have significant impact on trading activity of overseas investors, but not on other investors. The stock market return and securitised real estate return have significant impact on the trading activity of UK institutional investor and overseas investor, but have no significant influence on the trading behaviour of UK private investor and listed real estate company/REIT. 相似文献

This paper examines the international trade of a variety of genetically modified (GM) food products over a 27-year period (1984–2011) with data from the United Nations using the tools of social network analysis. The results indicate that each of the different crops have a distinctive pattern of trade that has changed over time due to a number of different factors. Also, trade in agricultural commodities became more diversified over time, dominated less by the United States and other nations central in the trade networks and trade in the individual GM crops was stable over time. Countries maintained their trading partners for specific crops, despite the adoption of the genetically modified varieties. The economic implications of these results are discussed for specific countries. 相似文献

社会互动对规模养殖户环保饲料支付意愿的影响研究*——基于改进的目标导向理论模型分析框架 总被引:1,自引:0,他引:1
[目的]通过引入社会互动变量改进目标导向行为理论框架,探讨生猪规模养殖户对环保饲料的支付意愿及其影响因素,为完善畜禽养殖污染防治政策提供参考借鉴。[方法]以湖北省生猪规模养殖户为研究对象,应用Heckman两阶段模型,研究规模养殖户对环保饲料的支付意愿。[结果]大多数规模养殖户(8134%)愿意采用环保饲料,且平均意愿支付水平为每头生猪饲料成本的669%(4680元/头)。社会互动中的干群互动、同行互动均能显著提升规模养殖户对环保饲料的支付意愿,但同时同行互动不利于其意愿支付水平的提升。进一步的异质性分析表明,在环保饲料支付意愿决策上,社会互动较少的规模养殖户更容易受到制度规范的约束,而社会互动较多的规模养殖户则更易受到感知养殖热情的影响。[结论]政府部门应加大生态环保宣传力度,并借助多种方式推动规模养殖户进行社会互动; 同时可依据社会互动程度的不同,分别制定相应措施以促进规模养殖户对环保饲料支付意愿的提升。 相似文献
