[Method] By using the sowing area, total yield, and yield per unit area of watermelon and melon in Hainan Province as research u- nits, the yield comparative advantage （YCA）, efficiency comparative advantage （E- CA）, scale comparative advantage （SCA）, concentration ratio comparative advantage （CRCA）, comprehensive comparative advantage （CCA）, ratio of yield per unit area （RYPA）, sowing area ratio （SAR）, and distribution characteristics of watermelon and melon were systematically analyzed. By referring to the agricultural statistic data of 18 counties （cities） in Hainan Province, indexes for each research unit （i.e., the YCA index, ECA index, SCA index, CRCA index, CCA index, RYPA index, and SAR index） were established and calculated to determine the comparative advantage of watermelon and melon production in Hainan Province. A spatial expression of the research result on a map was conducted by using GIS software. [Result] Seven counties （cities） exhibited comparative advantages in watermelon production, namely, Lingshui, Wanning, Wenchang, Dongfang, Sanya, Ledong, and Changjiang. The Eastern and Southern Hainan Provinces had CCAs, and the Western and Northern Hainan Provinces could be reserved for future development. For melon production, four counties （cities） exhibited comparative advantages, namely, Ledong, Lingshui, Sanya, and Dongfang. The Southern Hainan Province had CCA, whereas the West- ern Hainan Province could be reserved for later development. [Conclusion] The result has showed that establishing watermelon and melon as dominant agricultural prod- ucts is necessary for the future development of the industry and for the formulation of a layout of regions with advantages, where key support and construction should be provided preferentially with the aim to raise the yield, quality, and market com- petitiveness of products.展开更多

[Method] Based on the agricultural statistics data of Guangxi and al over China, yield com-parative advantage （YCA） index, efficiency comparative advantage （ECA） index, scale comparative advantage （SCA） index, concentration ratio comparative advantage （CRCA） index, comprehensive comparative advantage （CCA） index, ratio of yield per unit area （RYPA） index and sowing area ratio （SAR） index were established and calculated to determine the watermelon production comparative advantages in 31 provinces （cities） in China. Spacial patterns of the comparative advantages were produced by using GIS software. [Result] Nine provinces Shandong, Henan, Anhui, Hebei, Hubei, Jiangsu, Hunan, Zhejiang and Guangxi were the dominant regions in watermelon production al over the country. The Central and Eastern China showed the integrated comparative advantage in watermelon production, while the Southern, Northeastern, Northern and Northwestern China can be considered as the potential places for watermelon production in future. Southwest China gave more priority to watermelon production, so the comparative advantages kept increasing here. [Con-clusion] Based on this study, watermelon production should be a prior consideration among the agricultural products in Guangxi. Related measures should be developed to optimize the regional distribution of watermelon in Guangxi and China to promote healthy competition in watermelon production.展开更多

The results show that in the development of green economy,the mountain regions have factor endowment and development conditions with comparative advantage,but they are also facing more challenges. In the future,the mountain regions need to make favorable development measures based on their own comparative advantages from the following four aspects: at the top design level,it is necessary to ensure green development through institutional innovation; at the regional level,it is necessary to lead green development through the differentiation strategy; at the industrial level,it is necessary to support green development through transformation and innovation; at the social level,it is necessary to focus on protecting vulnerable groups and give full play to the role of women to promote sharing of green development achievements.展开更多

Our research findings suggest that without taking into account heterogeneity in firm's sales destinations and trade patterns,China's RVAE will be overestimated. Conventional gross trade accounting underestimates the export competitiveness of China's labor-intensive and capital intensive sectors, but overestimates the export competitiveness of China's technology-intensive sectors,which leads to a significant reversal of comparative advantages. Conventional gross trade accounting method overestimates the trade surplus of China's manufacturing and technology-intensive sectors with the US by about 60% and 85% respectively.展开更多

We find that most of the trades are inter-industry, with only a small portion being vertical intra-industry trades （IIT）. Our results confirm that Sino-US trade is complementary. We construct an imbalanced index of IIT, and identify the goods groups that aggravate and reduce the US trade deficit with China. We suggest an approach for calculating a dynamic IIT index that might mitigate the aggregation bias of the existing methodologies. Our improved index reveals that the dynamic imbalances of US-Chinese IIT in manufactured goods are worse than their static IIT imbalances, which means that it would be difficult to correct the deficit of US trade with China in the following couple of years. Adjusting and improving the structures of industries and products is China ＇s major task for sustainable trade growth.展开更多

Three measures of comparative advantage in manufactured goods have been applied in our study, including Balassa＇s revealed comparative advantage, the net manufactured export index, and the Michaely index. We also use four indicators of financial development to identify the different functions of regional financial development, and to determine both size and efficiency features of financial institutions. The estimation results suggest that besides factor endowments, foreign firms and infrastructure, financial development has a quantitatively large and robust effect on China ＇ s manufactured goods trade. Therefore, further reform of China＇s financial system should be encouraged to fully exploit the comparative advantage of China＇s foreign trade.展开更多

The analysis is undertaken using the concept of revealed comparative advantage, relative market shares, long-term trend analysis and statistical tests of convergence. In the context of the ASEAN market the evaluation of competition between India and China has been undertaken with special reference to the prior implementation of the ASEAN-China Free Trade Area relative to the ASEAN-India Free Trade Area. The results suggest that threat perceptions at the product level might currently prevail for both economies from each other across all sectors in both markets even though the intensity of the competitive threat varies across products. However, long-term trend analysis shows that the patterns of comparative advantage of India and China are evolving along divergent paths and, therefore, competition between the two economies might not be a major issue.展开更多

Adjusting and improving the structures of industries and products is China ＇s major task for sustainable trade growth.

文摘Using panel data for 29 provinces in China during 1990-2004, the present paper attempts to explore a possible link between financial development and China＇s foreign trade. Three measures of comparative advantage in manufactured goods have been applied in our study, including Balassa＇s revealed comparative advantage, the net manufactured export index, and the Michaely index. We also use four indicators of financial development to identify the different functions of regional financial development, and to determine both size and efficiency features of financial institutions. The estimation results suggest that besides factor endowments, foreign firms and infrastructure, financial development has a quantitatively large and robust effect on China ＇ s manufactured goods trade. Therefore, further reform of China＇s financial system should be encouraged to fully exploit the comparative advantage of China＇s foreign trade.
文摘This paper investigates the extent of competition between China and lndia in the world and ASEAN markets. The analysis is undertaken using the concept of revealed comparative advantage, relative market shares, long-term trend analysis and statistical tests of convergence. In the context of the ASEAN market the evaluation of competition between India and China has been undertaken with special reference to the prior implementation of the ASEAN-China Free Trade Area relative to the ASEAN-India Free Trade Area. The results suggest that threat perceptions at the product level might currently prevail for both economies from each other across all sectors in both markets even though the intensity of the competitive threat varies across products. However, long-term trend analysis shows that the patterns of comparative advantage of India and China are evolving along divergent paths and, therefore, competition between the two economies might not be a major issue.
