Automated content analysis of online travel reviews allows identification of topics of travelers' satisfaction, yet its domain is not well researched. We suggest that the Anna Karenina principle positing a greater variability of the factors leading to business failure as opposed to those leading to success can be applied to the domain of visitors’ reviews of historic and cultural attractions. The larger variability of issues in reviews of dissatisfied visitors is likely to result in limitations for automated topic modeling. We confirm our proposition using TripAdvisor reviews of the Terracotta Army museum in China, and validate the outcome with two additional sites. The study strongly suggests that application of unsupervised topic mining algorithms to negative reviews may be problematic and the results should be treated with caution. The main themes of dissatisfaction of visitors to all three sites are reported and practical implications for management of the attractions are discussed.  相似文献

Developing and transitional countries often impose a wide variety of entry barriers on foreign direct investments (FDIs). One important reason behind these entry barriers is ideological taboos. However, do these taboos actually affect the inflow of FDIs? With the help of China’s “cultural system reform,” this study uses a panel data of 283 prefecture-level cities in China for 1994–2017 and the difference-in-differences method to evaluate the effect of the cultural system reform on regional FDI. We found that the cultural system reform remarkably promoted the inflow of FDIs by deregulating institutions and removing entry barriers, and the attraction of FDI has slowly increased along with the deepening of the reform. Our conclusions still hold after performing several robustness tests, thereby highlighting ideologies as important barriers to the inflow of FDIs into less developed countries.  相似文献

2019 is the 70 th anniversary of the founding of the people’s Republic of China and the key year for implementing the rural vitalization strategy.Summarizing the great achievements made by agriculture and rural areas in the past 70 years will have an important theoretical value for promoting the modernization of agriculture and rural areas and the strategy of rural revitalization.Under such circumstances,the 10 th member congress and 2019 academic seminar of CAAE was successfully held in Beijing.The key to promote rural revitalization lies in deepening rural reform,focus on the property right system and market-oriented allocation of factors,and establish a system and mechanism of free circulation and equal exchange between urban and rural areas.In order to promote the organic connection between small-scale peasant and the modern agriculture,it is necessary to speed up the development of agriculture social service industry.Finally,it is suggested to adhere to the two-wheel drive of rural revitalizationand new urbanization,promote the effective coverage of rural public services,and improve the rural governance mode of combining autonomy,rules of law and virtue.  相似文献

资本市场应当主导我国金融市场由资金配置向资本配置转型、由不动产金融向动产金融转型,同时主导我国生产要素市场化改革。资本市场在经济活动中发挥主导作用的关键在于提升其价值发现能力,而当前我国资本市场价值发现能力欠缺有多方面深层次原因:一是对资产和资金的包容和汇聚不够,二是资本的流动和配置受到制约,三是定价机制受到一定程度的扭曲,四是产权制度不完善,五是市场主体归位尽责情况不理想,六是金融衍生品市场不够成熟。本文建议:一是完善多层次资本市场建设,二是推动市场多空机制均衡发展,三是纠偏资本市场定价机制,四是加速完善现代产权制度,五是强化对市场各主体的培育,六是加强资本市场高质量对外开放。  相似文献

The outbreak of the COVID-19 pandemic has drastically disrupted the air cargo industry. This disruption has taken many directions, one of which is the demand imbalance which occurs due to the sudden change in the cargo capacity, as well as demand. Therefore, the random change leads to excessive demand in some routes (hot-selling routes), while some other routes suffer from a big shortage of demand (underutilized routes). Routes are substitutable when there are several adjacent airports in the Origin & Destination (O&D) market. In this market, demand imbalance between substitutable routes occurs because of the above reasons. To tackle the demand imbalance problem, a novel model is introduced to estimate the quantity combinations which maintains the balance between underutilized and hot-selling routes. This model is a variant of the classic Cournot model which captures different quantity scenarios in the form of the best response for each route compared to the other. We then cultivate the model by integrating the Puppet Cournot game with the quantity discount policy. The quantity discount policy is an incentive which motivates the freight forwarders to increase their orders in the underutilized routes. After conducting numerical experiments, the results reveal that the profit can increase up to 25% by using the quantity discount. However, the quantity discount model is only applicable when the profit increase in the hot-selling route is greater than the profit decrease in the underutilized route.  相似文献

地方政府“以地谋发展”的策略在促进各地区制造业大规模集聚和出口贸易快速增长的同时,也势必会给企业出口产品质量带来深刻影响。本文综合利用中国土地市场网城市土地交易数据、中国工业企业数据、中国海关进出口产品数据和中国城市面板数据,实证检验了土地市场扭曲对企业出口产品质量升级的影响,并对其内在机制进行了探讨。研究发现:中国城市建设用地配置存在明显的工业偏向性,进而导致工业用地价格被低估,产生工业用地应得收益大于实际价格的反向扭曲问题。这种反向扭曲可通过抑制技术进步、阻碍产业结构高级化、弱化集聚经济效应等机制显著降低制造业企业出口产品质量。土地市场扭曲对企业出口产品质量升级的影响具有明显的异质性特征。具体而言,土地市场扭曲不利于一般贸易企业与混合贸易企业出口产品质量提升,但对加工贸易企业出口产品质量提升具有促进作用。土地市场扭曲对企业出口产品质量升级的抑制作用由东到西依次递增。土地市场扭曲不利于外资企业和国有企业出口产品质量提升,对集体企业及民营企业的影响不显著。  相似文献

In the context of personal income tax (PIT) reform in China in 2018, this paper examines some of the major issues of concern regarding the reform and income distribution. Using the China Personal Income Tax Micro‐simulation model, the paper compares the differences between the 2011 and 2018 PIT systems, and finds that residents relying on different income sources may face a large degree of real tax rate change. Once the tax system is altered to PIT 2018, the coverage of PIT for wage earners will decrease from 46.9 to 23.4 percent, the income redistributive effect will drop from 1.95 to 1.22 percent and the PIT's role in fiscal revenue will also be negatively affected. Nevertheless, if individual income continues to grow, the share of PIT in fiscal revenue is expected to return to the 2018 level in 2022, but its income redistribution function is difficult to recover in the short term. The paper finds that the effect of PIT on income distribution depends on the tax structure. Gradual transition to an “entirely comprehensive” tax system when conditions are appropriate will achieve better income redistribution results at a lower average tax rate.  相似文献

China is undergoing its long-awaited industrial revolution. There is no shortage of commentary and opinion on this dramatic period, but few have attempted to provide a coherent, in-depth, political-economic framework that explains the fundamental mechanisms behind China’s rapid industrialization. This article reviews the Embryonic Economic Development theory put forth by Wen (2016a). This article reviews the Embryonic Economic Development theory put forth by Wen . It illuminates the critical sequence of developmental stages since the reforms enacted by Deng Xiaoping in 1978: namely, small-scale commercialized agricultural production, proto-industrialization in the countryside, a formal industrial revolution based on mass production of labor-intensive light consumer goods, a sustainable ‘industrial trinity’ boom in energy/motive power/infrastructure, and a second industrial revolution involving the mass production of heavy industrial goods. This developmental sequence follows essentially the same pattern as Great Britain’s Industrial Revolution, despite sharp differences in political and institutional conditions. One of the key conclusions exemplified by China’s economic rise is that the extent of industrialization is limited by the extent of the market. One of the key strategies behind the creation and nurturing of a continually growing market in China is based on this premise: The free market is a public good that is very costly for nations to create and support. Market creation requires a powerful ‘mercantilist’ state and the correct sequence of developmental stages; China has been successfully accomplishing its industrialization through these stages, backed by measured, targeted reforms and direct participation from its central and local governments.  相似文献

This paper analyses the rise and fall of two regional monocultures in Mexico: the henequen zone in the southern state of Yucatán and the cotton‐growing area of La Laguna. Both regions experienced a dramatic expansion of commodity production between 1870 and 1910, but their key crops came to be cultivated under different labour regimes: debt peonage in the case of henequen and wage labour in the case of cotton. The process of class formation that unfolded in each region culminated in the 1930s in different kinds of crises. In Yucatán, a political struggle between hacienda owners and the federal government resulted in an agrarian reform “from above.” In La Laguna, class conflict between rural wageworkers and the landed bourgeoisie forced an agrarian reform “from below.” These previously distinct labour regimes converged in subsequent decades, however, as rural producers became de facto wageworkers on state‐organized and state‐administered production units known as collective ejidos. Ultimately, changes in the global markets for cotton and henequen, combined with the inability of the Mexican state to reconcile the political logic of agrarian clientelism with shifting commodity chain dynamics, resulted in the collapse of these regional monocultures in the late 20th century.  相似文献
