在中国人口增长趋势放缓的背景下,本文利用中国城市人口数据和制造业企业微观层面的数据探讨了人口集聚对企业出口技术复杂度的影响。首先,对企业所在城市的人口集聚和企业出口技术复杂度进行测度,运用计量回归模型进行实证研究,发现人口集聚对企业出口技术复杂度有显著的促进作用,并且通过了一系列稳健性检验;其次,在异质性检验中发现中小城市的企业相较于大城市的企业、国有企业相较于非国有企业,出口技术复杂度未受到人口集聚的显著影响;再次,本文还检验了人口集聚影响企业出口技术复杂度的三个渠道:企业创新、企业高技术产品出口目的地多元化和企业对外直接投资。在拓展分析中,本文利用人口普查数据验证了人口集聚对企业出口技术复杂度的提升作用。根据研究结论,本文从人口集聚角度提出相应政策建议以推动中国对外贸易高质量发展。 相似文献

Corr-LDA-ITD模型较Corr-LDA模型具有更高的文本图像关联性,并且类标信息可以一定程度影响标注的准确性。基于此,文章首先利用Corr-LDA-ITD模型对不同类别的图像进行训练,然后用每类图像训练出的模型对测试图像进行测试,选出log似然值最大的标注模型对图像进行标注。在2个真实图像集(Labelme和Uiuc-sport)上的实验结果表明该方法的标注效果较好。 相似文献

信息时代背景下,图书馆作为一种信息资源,同样需要依赖用户的行为反馈实现资源有效利用,帮助图书馆精准定位、提升服务、增强用户黏性。文章从SOR视角探索高校图书馆用户管理政策对大学生用户的影响力,构建高校图书馆用户管理政策影响力模型,并通过在线问卷收集470份有效数据,利用SPSS和Amos 24.0软件进行数据分析,对模型进行实证检验。结果显示,政策科学性、导向显著正向影响用户感知,用户感知则进一步显著正向影响用户行为意愿。本研究拓展了图书馆如何影响用户的研究领域,并为图书馆如何更好地服务用户提供一定的建议。 相似文献

The bio-control potential of rhizospere bacteria Pseudomonas fluorescens against plant-parasite nematode had been demonstrated. P. fluorescens had shown the effect to enhance tobacco resistance to root-knot nematode Meloidogyne incognita. Inoculation with P. fluoreseens in tobacco could lead to significant reductions in the number of juveniles that penetrated tobacco root and further life stage development of the juveniles. The number of juveniles penetrated into tobac- co root in treatment with P. fluorescens is significantly different from CK at 2DAI, 6DAI, 8DAI and 10DAI. Significant reduction and delayed development of juveniles that penetrated into tobacco root and treated were observed in treatment at 14DAI, 21DAI, 28DAI and 35DAI. In addition, P. fluoreseens treatment leads to a significant reduction in the number of eggs per egg-mass at 35 DAI. The results show P. fluorescens induced a continuously suppression on root-knot nema- tode M. incognita throughout their entire early infection phase of root penetration, subsequent life stage development and reproduction. 相似文献

Indonesia’s economic growth picked up slightly in mid-2016 but remains below the level demanded by government and popular aspirations. Despite a plethora of reforms intended to increase efficiency and productivity, some policies are perverse and longstanding problems of implementation remain. The share of manufacturing has declined, the real exchange rate has appreciated, exports have dwindled, and growth has been trending downwards. The banking sector is stable but inefficient, with wide net interest margins and numerous barriers to competition. Trade protection, particularly in basic food commodities, has created high costs that weigh particularly heavily on the poor. Declining government revenues have placed increasing pressure on the public budget, even as the current administration aims to increase spending on infrastructure and welfare and to enhance productivity. In an effort to increase revenues, the government has announced a tax amnesty program and other measures. In addition, Sri Mulyani Indrawati, the new finance minister, has taken steps to cut non-essential expenditure in order to secure high spending on infrastructure and at the same time keep within the 3% budget deficit limit stipulated by law. Although the overall debt situation is not yet alarming, declining revenues and budget cuts that do not fully reflect this decline are putting pressure on increasing debt levels. The government’s high-profile tax amnesty program was the major policy initiative implemented in the second half of 2016 that aimed to relieve this pressure. Despite widespread criticism of, and scepticism about, the tax amnesty (both within and outside Indonesia), its first phase had a much higher participation rate than most independent accounts expected. Revenues raised so far through the amnesty are less than 60% of the official target, but this is actually a strong result for the short term. The bigger question, however, is whether the amnesty is a key element of a more encompassing strategy to overhaul the system of taxation and tax administration. 相似文献

In this paper, I analyze the causes of the prolonged slowdown of the Japanese economy in the 1990s and find that the stagnation of investment, especially private fixed investment, was the primary culprit. I then investigate the causes of the stagnation of household consumption during the 1990s and find that the stagnation of household disposable income, the decline in household wealth, and increased uncertainty about the future are among the contributing factors. Finally, I consider whether demand side factors or supply side factors were more important as causes of the prolonged slowdown of the Japanese economy in the 1990s and conclude that the former (especially misguided government policies) were probably more important. 相似文献

城市社会在对农民的开放与封闭之中徘徊。改革开放后城市社会对农民的开放已经使很多农民城市化。城市社会对农民的封闭已由政策性封闭转向经济性封闭。城市社会对农民的封闭增加了农民城市化的成本和社会风险。必须加强城市社会对农民的开放,逐步消除对农民的封闭政策,以推进农民的城市化。 相似文献
