选取2013—2020年省级面板数据,采用熵值法、K-Means聚类分析法对我国数字经济和高质量就业水平进行测度评价,通过面板模型、分维度回归、门槛效应模型,研究数字经济对劳动力高质量就业的影响。研究发现,数字经济和高质量就业水平二者均在时间趋势上呈增长趋势,空间特征上均表现为东部高、中西部低;数字经济有助于促进劳动力高质量就业;信息化发展、数字交易发展、数字金融普惠发展能显著促进劳动力高质量就业,互联网发展对高质量就业的影响不显著;数字经济对劳动力高质量就业的促进作用呈“边际效应”递增的非线性特征;不同地区的数字经济对高质量就业的影响差异显著。 相似文献

我国存在着双重的二元经济结构,这对流入我国FDI的性质有着重要的影响。本文的实证结果显示,2002~2009年我国东部地区的外资利用以能带来更大技术溢出并促进产业结构升级的水平型FDI为主,我国中部地区FDI性质不明确,而西部地区的外资利用则以垂直型为主。门槛回归结果显示,我国各地区不同的金融发展水平、对外依赖度以及国家干预程度对流入我国FDI性质都存在明显的门槛效应。 相似文献

随着我国经济进入新常态,创新驱动日益成为经济增长的主要引擎。基于2009—2017年我国31个省级面板数据,利用门槛回归模型,分析了在不同税收水平下我国区域创新能力对经济增长的影响。研究结果表明,在2009—2017年期间,我国区域创新能力对经济增长的影响表现为非线性关系,并呈现出"先下降、后上升"的U形特征。根据门槛模型的测算结果,当税收水平在0~74.81区间时,区域创新能力对经济增长有显著抑制作用;当税收水平在74.81~182.23区间时,负面影响仍然存在,但抑制作用逐渐减弱;当税收水平大于182.23时,我国区域创新能力对经济增长的促进作用开始增强。通过对比我国东、中、西部地区,发现在不同税收水平下,区域创新能力对东部地区经济增长促进作用明显,但对中、西部地区的影响不显著。 相似文献

文章通过理论机制分析认为,资本账户开放通过经济增长、通货膨胀和经常账户波动三个渠道对一国的就业率产生影响。鉴于此,文章使用多门槛面板回归模型,对66个样本国家进行多层嵌套分组并分析了不同类型国家资本账户开放与就业的非线性关系。研究发现:首先,资本账户开放对就业确实存在门槛效应,且在人均GDP水平、通胀水平和经常账户余额三个门槛变量上都存在显著的双门槛效应;其次,资本账户开放对就业的影响与经常账户余额之间呈现非单调的关系;最后,不同类型国家资本账户开放的就业效应存在显著差异,为了提高就业率,一些新兴经济体可以适当推进资本项目的开放,对于部分发达国家应当加强对跨境资本流动的管制,而我国则应在逐步放开资本账户的同时维持经常账户的盈余以及深化金融市场的发展。 相似文献

在理论分析上,将劳动生产率和人口老龄化引入索洛经济增长模型,利用数理推导得出老龄化与劳动生产率存在非线性关系。实证层面上,基于2000-2017年省级面板数据,通过面板固定效应回归以及面板门槛回归分析了老龄化对劳动生产率的影响。研究结果表明:一、老龄化与劳动生产率存在"U"型曲线关系,二者现阶段处于"U"型曲线的左侧,即现阶段老龄化降低了劳动生产率;二、当企业转型升级或生产技术增长到一定阶段,老龄化与劳动生产率就呈同方向变化;三、虽处于"U"型曲线的左侧,但老龄化对劳动生产率的反向效应并不平滑,存在门槛效应。 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
