基于改进关键词重要性和近邻传播聚类算法,提出了一种学科领域主题分析方法,通过词频分析法和作者潜意识行为计算高频关键词权重,借助共词分析和Ochiai系数构建带权重高频关键词相似性矩阵,利用近邻传播聚类算法对学科领域主题进行自适应提取与分析。以CSSCI收录的2015—2019年物流学科领域期刊论文为研究对象,借助新方法对其进行主题分析,研究结果表明:高重要性的关键词不一定是核心主题,核心主题与同一簇内其它成员关键词最为相似。与此同时,近五年物流学科存在“降本增效”“区域物流一体化”“现代物流技术研究与创新”“物流体制改革与产业转型升级”“农村物流与农产品物流”“电子商务与跨境电商”“可持续发展理念”等七大热门主题。 相似文献

At its 19th National Congress, the Communist Party of China vowed to “strengthen the financial sector’s ability to serve the real economy.” However, many studies provide evidence of the opposite trend, a problematic “transition from the real to the virtual,” among Chinese enterprises. Meanwhile, the investment efficiency of China’s Social Security Fund (SSF), a public fund, attracts much attention. In this context, we use A-share listed companies in China from 2009 to 2018 to study the relationship between holding by the SSF and enterprise financialization. We find that SSF holding significantly inhibits financialization and that this effect is non-linear. Mechanism analysis indicates that SSF holding suppresses enterprises’ financialization mainly by improving their governance. Moreover, SSF holding more strongly inhibits small-scale (vs. large-scale), state-owned (vs. non-state-owned), and non-eastern (vs. eastern) enterprises in China. Furthermore, SSF holding can alleviate corporate value impairment caused by financialization. The conclusions enrich theoretical research and provide empirical evidence that may help regulatory authorities to guide investment by enterprises and prevent financial risks. 相似文献

This paper presents a methodology for the formulation and testing of economic growth models. The model selected includes
two production sectors with physical and human capital accumulation. These capital stocks are associated with spillover effects
in the production of the physical good and in the accumulation of both factors. 相似文献

Endogenous lifetime and economic growth 总被引:5,自引:0,他引:5

Endogenous mortality is introduced in a two-period overlapping generations model: probability of surviving from the first period to the next depends upon health capital that is augmented through public investment. High mortality societies do not grow fast since shorter lifespans discourage savings; development traps are possible. Productivity differences across nations result in persistent differences in capital-output ratios and relatively larger gaps in income and mortality. High mortality also reduces returns on education, where risks are undiversifiable. When human capital drives economic growth, countries differing in health capital do not converge to similar living standards, ‘threshold effects’ may also result. 相似文献

We analyze two cross-country data sets that contain information on attitudes toward trade as well as a broad range of socio-demographic and other indicators. We find that pro-trade preferences are significantly and robustly correlated with an individual's level of human capital, in the manner predicted by the factor endowments model. Preferences over trade are also correlated with the trade exposure of the sector in which an individual is employed: individuals in non-traded sectors tend to be the most pro-trade, while individuals in sectors with a revealed comparative disadvantage are the most protectionist. Third, an individual's relative economic status has a very strong positive association with pro-trade attitudes. Finally, non-economic determinants, in the form of values, identities, and attachments, play an important role in explaining the variation in preferences over trade. High degrees of neighborhood attachment and nationalism/patriotism are associated with protectionist tendencies. 相似文献

This paper analyzes the existence of developmental views and compares the results of previous studies for underdeveloped regions.In view of the limitations of previous studies,this study details regional unit,expands index system,applies factor-analysis to structure index system,uses the fuzzy comprehensive evaluation model to improve analytic hierarchy process,and identifies the economic developmental levels of 384 regions,including 4 municipalities,333 cities at prefecture level,and 47 counties under the jurisdiction of province.The levels of the 47 counties are identified by dividing the rank of comprehensive values of more than 337 regions unit into five equal graduations and then matching the 47 counties with the five-graduation results.This study provides the distribution of resources-rich region in China qualitatively and quantitatively in terms of coal,oil gas and other 14 kinds of metal mineral resources.Finally,by matching the two parts of results,this study identifies the distribution of underdeveloped resource-rich regions (URRRs).URRRs are mainly distributed in Shaanxi,Shanxi,Guizhou,Yunnan,Sichuan,He 'nan,Shandong,Guangxi and Gansu provinces,which accounts for 78.57% of the total in China.To a certain degree,the result of this paper proves that "resources curse " existing in the national stratification plane in later 20^th century still takes places in some cities in China,especially in the counties of these cities 'jurisdiction. 相似文献

Tax competition and tax structure in open federal economies: Evidence from OECD countries with implications for the European Union 总被引:1,自引:0,他引:1
Timothy J. Goodspeed 《European Economic Review》2002,46(2):357-374
Tax competition arguments suggest that governments that operate in an open economy (such as local governments) should not and will not rely on non-benefit taxes, such as the income tax. Yet we observe reliance on income taxes by local governments in many countries, and such reliance changes over time. Evidence from a panel data set of 13 OECD countries over the period 1975-1984 suggests that competition between levels of government (resulting in a vertical fiscal externality) and between governments at the same level (resulting in a horizontal fiscal externality) provide some economic rationale for these changes. Moreover, the evidence indicates that the vertical and horizontal fiscal externalities interact. These results have some interesting implications for fiscal policy in the European Union, particularly as the EU continues to evolve. One implication for the EU is that enlargement that increases tax base disparities within the EU (and is not accompanied by an EU-level income tax) will tend to lower national income tax rates, although this must be qualified because it also depends on the mobility of the population. A second implication is that fiscal expansion of the EU to include an EU-level income tax may tend to lower the reliance of national governments on income taxes through the vertical externality, but may also tend to equalize tax bases across countries, and so increase reliance on national income taxes through the horizontal externality. 相似文献
