We examine a standard, gravity model of international commerce, augmented to include political as well as institutional influences on bilateral trade. Using annual data from 1980-2001, we estimate regression coefficients and residual dependencies using a hierarchy of models in each year. Rather than gauge the generalizability of these patterns via traditional measures of statistical significanc...

China’s renewable energy products have an important place in international trade, and the conclusion of RCEP agreement can create favourable external conditions for product exports. This paper measures export potential to other countries through a trade gravity model. The results show that (1) GDP importing exporting countries, consumption particulate emissions damage significantly enhance expo...

By using social network analysis methods to analyze the Xinjiang tourism economy network centricity nodes, network density and core-edge structure, and study its effect. The results show that economic network of tourism in Xinjiang is becoming complicated and unbalanced. Finall...

BACKGROUND We investigated 18-month incidence and determinants of death and loss to follow-up of children after antiretroviral therapy (ART) initiation in a multiregional collaboration in lower-income countries.

Various studies on ancient DNA have attempted to reconstruct population movement in Asia, with much interest focused on determining the arrival of European lineages in ancient East Asia. Here, we discuss our analysis of the mitochondrial DNA of human remains excavated from the Yu Hong tomb in Taiyuan, China, dated 1400 years ago. The burial style of this tomb is characteristic of Central Asia a...

This paper examines the existence of long-run relationships between East Asian economic integration and tourism exports for nine selected ASEAN States for the period 1996-2007. I employ tourist arrivals data as a proxy for tourism exports and trade ratios as a proxy for the economic integration. Using Johansen’s Fisher panel cointegration test, the findings show that tourist arrivals and trade ...

4.1 Abstract We examine a crosscountry data set of 6 East Asian countries 1 for the period of 19802006 with the aim to study the interrelationship between trade liberalization and environmental degradation. On the basis of the parametric econometric model, we investigate trade liberalization’s impact on the environment quality 2 . We take two environmental indicators for analyses that are carbo...
