Trends and Features of China's Inter-Provincial Trade:1987-2007

With today's economic globalization,inter-provincial trade plays an important role in a country's economy.This paper is the first to adopt the input-output tables of 30 Chinese provinces and to summarize the evolution of China's inter-provincial trade from1987 to 2007.This paper reaches the following conclusions.First,China's inter-provincial trade has sustained a period of rapid growth.In 2007,the total volume of inter-provincial trade was twice the amount of international trade,with the eastern region accounting for the majority of the inter-provincial trade volume.GDP may have a greater effect on interprovincial trade than geographic distance does.Second,inter-provincial trade maintains a high level of concentration and overlaps with the high concentration of GDP.Third,the inter-provincial trade dependence of Chinese provinces tends to increase,an indication of the growing domestic market integration.Moreover,the eastern region's dependence on inter-provincial trade is higher than the central and western regions'.Fourth,the share of inter-provincial trade in the overall external trade of Chinese provinces has a declining tendency,which indicates a slower process of China's domestic market integration compared with international market integration.However,in terms of proportion,the external trade of most Chinese provinces is still dominated by inter-provincial trade.Fifth,most provinces with longstanding inter-provincial trade deficits are in the central and western regions.

Accounting Research about Soot Emission Caused by Coal Combustion in Chongqing

As rapid development of economy and acceleration of urbanization process, air pollution problem in Chongqing was more and more prominent. By referring to statistical yearbook and investigating energy usage and economy activity levels of various industrial sectors of Chongqing, basic data （activity level, energy production and consumption situation） of various economic sectors of Chongqing during 2007 -2012 were ob- tained. Using emission coefficient method, soot emission inventory in Chongqing during 2007 -2012 was established. Meanwhile, input-output model containing environmental factor was established to study relationship between economy development and environmental protection and number relationship between economy development and pollutant emission. According to the results, countermeasures of emission reduction in Chongqing were put forward.

Research on Measurement of China’s Inter-Provincial Trade,International Trade and Low-Carbon Trade Competitiveness

In this paper,Embodied carbon emission competitiveness in international trade and inter-provincial trade is measured and comparative analysis is conducted.Specifi cally the non-competitive input-output model and low-carbon trade competitiveness index are constructed to study the embodied carbon emission competitiveness of 31 Chinese provinces in international trade and inter-provincial trade from the perspectives of the whole,three industries and product sectors.We find that Shanghai is the most competitive in low-carbon trade,while Qinghai is the least;carbon leakage in international trade is severe;the performance of different product sectors differ widely in embodied carbon emission competitiveness in international trade and inter-provincial trade;the primary and secondary industries are competitive in low-carbon inter-provincial trade and the tertiary industry is competitive in low-carbon international trade.The innovations of this paper is as follows:methodology in low-carbon trade competitiveness index is innovated;macro,meso and micro perspectives are taken;factors in international trade and inter-provincial trade are combined in content.In the end,development of low-carbon trade is promoted and references for policy are provided for a new round of trade competition.

Wood Pellet Co-Firing for Electric Generation Source of Income for Forest Based Low Income Communities in Alabama

Alabama imports coal from other states to generate electricity. This paper assessed the direct and indirect economic impacts of wood pellet production to be co-fired with coal for power generation in Alabama. Four sizes of wood pellet plants and regional input-output models were used for the analysis. The results showed that the economic impact increases with the size of the plant. Wood pellet production will have a multiplier effect on the economy especially, forest-related services, retail stores, the health service industry, and tax revenue for the government. Domestic wood pellet production can reduce the use of imported coal, allow the use of local woody biomass, and create economic activities in Alabama’s rural communities. Policies that support the production of wood pellet will serve to encourage the use of wood for power generation and support the rural economies.

Dynamic features and driving mechanism of coal consumption for Guangdong province in China

Guangdong Province,as one of China’s fast-developing regions,an important manufacturing base,and one of the national first round low-carbon pilots,still faces many challenges in controlling its total energy consumption.Coal dominates Guangdong’s energy consumption and remains the major source of CO_(2).Previous research on factors influencing energy consumption has lacked a systematic analysis both from supply side(factors related to scale,structure,and technologies)and demand side(investment,consumption,and trade).This paper develops the logarithmic mean Divisia index(LMDI)method that focuses on the supply side and the structural decomposition analysis(SDA)method that focuses on the demand side to systematically identify the key factors driving coal consumption in Guangdong.Results are as follows:(1)Supply side analysis indicates that economic growth has always been the most important factor driving coal consumption growth,while energy intensity is the most important constraining factor.Industrial structure and energy structure have different impacts on coal consumption control during different development phases.(2)Demand side analysis indicates that coal is consumed mainly for international exports,inter-provincial exports,fixed capital formation,and urban household.(3)Industries with the fastest coal consumption growth driven by final demand have experienced significant shifts.Increments in industrial sectors were mainly driven by inter-provincial exports and urban household consumption in recent years.(4)Research on energy consumption in subnational regions under China’s new development pattern of“dual circulation”should not only focus on exports in the context of economic globalization but also pay more attention to inter-provincial exports on the background of strengthened interregional connections.
