城镇化、收入分配与进口贸易

城镇化是中国经济持续发展的重要战略平台,影响着个人收入水平的变动及收入分配差距的变化,从而对进口贸易规模及结构产生影响。本文通过VAR模型的构建、Granger因果检验和脉冲图,对城镇化发展影响个人收入分配差距、个人收入分配差距影响中国进口贸易进行分析。研究结果表明：城镇化发展对个人收入分配差距具有长期、相互的影响作用,个人收入分配差距变化对进口贸易增长具有正态效应。应采取相应措施,通过个人收入分配媒介,发挥城镇化对进口贸易的刺激效能。     

How Service-Related Factors Affect the Survival of B2T Providers: A Sentiment Analysis Approach

ABSTRACT

Nearly one-third of the business-to-team (B2T) websites in China closed down in 2011—the casualties of the intensified competition in the group-buying market. To investigate the critical factors to the survival of online B2T businesses in an overcrowded buyer-side market, we propose a model that links convenience, price, product/service, personalization, and website security/safety to customer satisfaction of B2T websites in light of the related literature. A two-stage approach is applied to validate this model. In Stage I, according to the results of an empirical analysis based on questionnaire responses from 157 B2T website users, we found that convenience and product/service are the top two contributors to the success of B2T business, as measured by customers’ repurchase intentions. In Stage II, topic classification and sentiment analysis are applied to 3046 review comments related to 58 B2T websites. The results from the Stage II study confirm the validity of the Stage I results with further evidence to support our arguments.

The Effectiveness of the Escrow Model: An Experimental Framework for Dynamic Online Environments

This article investigates the mechanism of an online escrow service (OES) in online consumer-to-consumer (C2C) auctions. We develop a discrete-event driven simulation model for the dynamics of an OES adoption in electronic markets that involves four types of agents: the strategic trader, the moral trader, the OES provider, and the law-enforcement agent. By applying the Monte Carlo method in computer-based simulations, we demonstrate that the OES business model can effectively block fraud attempts and promote security in online C2C auction markets. However, our findings reveal that the prevailing OES fee rates are not necessarily set at the profit maximization level. Meanwhile, the simulation results show that the legal mechanisms in electronic markets directly impact the profit of escrow services.     

Study on Coupling Coordination between Sci-Tech Innovation and High-Quality Economic Development in the Guangdong-Hong Kong-Macao Greater Bay Area

Sci-tech innovation is an important measure for the Guangdong–Hong Kong–Macao Greater Bay Area to achieve high-quality economic development. Theoretically, there is a coupling coordination relationship between sci-tech innovation and high-quality economic development, and coordinating the relationship between the two is beneficial to building the Guangdong–Hong Kong–Macao Greater Bay Area into an international innovation and technology hub and promoting high-quality economic development. At present, the Guangdong–Hong Kong–Macao Greater Bay Area has seen a year-on-year increase in both the level of sci-tech innovation and the level of high-quality economic development, with a sound development trend. Its coupling coordination degree between sci-tech innovation and high-quality economic development has steadily improved from a slightly uncoordinated stage to a primarily coordinated stage, but the overall degree of coordination is still not high, with some gaps from realizing the excellently coordinated stage. From the perspective of spatial distribution, the internal development of the Guangdong–Hong Kong–Macao Greater Bay Area is unbalanced, with obvious differences in development level and coupling coordination degree among cities. The convergence analysis shows that the differences in the coupling coordination degree among the cities in the Guangdong–Hong Kong–Macao Greater Bay Area have stabilized after narrowing during the study period. However, the difference among the cities with higher coupling coordination degrees tends to widen in recent years. Therefore, necessary measures should be taken to promote the coordination between sci-tech innovation and high-quality economic development in the Guangdong–Hong Kong–Macao Greater Bay Area.
