The role of oil and gas in China's energy strategy: an overview

China is well endowed with energy resources, having large quantities of coal, oil, gas and hydropower, as well as tremendous solar, wind and biomass energy potential. It even has its own uranium. To date, the country has relied mainly on coal and hydropower to generate its electricity and on oil to power its vehicles. However, with climate change and consequent rising sea levels, increased incidence of drought, intense storms, etc., China, having become the world's largest emitter of CO_2, is under strong international pressure to re-examine its energy strategy and find ways to reduce its carbon emissions. Thus, the government plans to greatly increase its use of natural gas in power generation. Gas emits less than half the CO₂ that coal emits. It is argued here that over the next 20 years, massive imports of gas via pipeline and liquefied natural gas tankers, combined with the development of unconventional gas reserves in the country may partly substitute for the large quantities of coal currently being used to generate electricity, but will not likely completely replace them. As for transport fuels, China, like all other countries, has little choice but to continue relying on oil regardless of whether it is imported or China develops its own large-scale shale oil operations. There is no alternate fuel of the same density available at the same or better price. The use of biofuels and electric/hybrid vehicles will not supplant the use of gasoline or diesel in the near future. Thus, the role of oil and gas in China's energy strategy are set to remain very significant over the next 20 years.     

微生物合成气发酵生产生物燃料的研究

许多生物质原料（如秸秆和木材）不易被微生物直接降解并转化为生物燃料。而将它们气化为合成气就可解决这一问题，因为有些微生物是能够利用CO和H2（合成气的基本组成部分）合成多碳化合物的。而氢气又可以由一氧化碳自养氢气生成菌在利用CO和H2O进行生长的过程中提供。但是，目前只有少数的嗜热菌能良好地利用合成气生长，而能够被用来进行有机化合物生产。新菌株的分离鉴定和代谢工程将扩大合成气发酵的产品范围。另外，尽管基因手段目前无法用于此生产过程，合成气发酵在生物燃料生产方面仍然有优势并具有潜力。

Value co‐creation between foreign firms and indigenous small‐ and medium‐sized enterprises (SMEs) in Kazakhstan's oil and gas industry: The role of information technology spillovers

Study related to the extractive sector still plays a limited role in the mainstream international business (IB) and management literature, with even less focus on ongoing liberalization and digitalization in the industry. This article was motivated by the question of how collaboration between foreign and indigenous oil and gas (O&G) companies can support small‐sized and medium‐sized indigenous technological development. The main contribution of this article is the development of a model that explains how different actors can cocreate value in the ecosystem of the O&G industry through digital technologies. A three‐stage qualitative–interpretive method based on interviews with industry experts was adopted to build three vignette case studies. This article proposes what companies and the government could do to increase the competitiveness of the local economy, diversify from O&G into high technological industries, and support industrial development through information and communication technologies (ICT).     

The impact of parallel market exchange rate volatility and oil exports on real GDP in Syria: Evidence from the ARDL approach

This paper investigates the impact of parallel market exchange rate volatility and trade on real GDP and real GDP growth in the Syrian economy over the period of 1990Q1–2010Q4. To this end, we first construct a parallel market exchange rate volatility indicator. Second, we estimate an autoregressive distributed lag (ARDL) model where we include our indicator of volatility among the main determinants of real GDP. Our findings imply that real GDP can be explained by three main variables: parallel market exchange rate, money supply, and oil exports. The long-run equilibrium reveals that parallel market exchange rate volatility has a negative impact on real GDP compared to the positive impact of money supply and oil exports. In contrast, the short-run impact of parallel market exchange rate volatility on real GDP growth is positive and very small counter to the long-run impact. Furthermore, the coefficient of the error correction term of the estimated ARDL model indicates that real GDP deviation from the equilibrium level will be corrected by about 10% after each quarter.     

Export diversification,composition, and economic growth: Evidence from cross-country analysis

We investigate the export-growth relationship at disaggregate levels – disaggregation both at the country level and at the level of exports – focusing on the diversification and the composition of exports of countries. In a sample of 65 countries for the period 1965–2005 the dynamic panel estimation reveals that both diversification and composition of exports are important determinants of economic growth after controlling for the impacts of other variables like lagged income, investment, and infrastructure. There is a critical level of export concentration beyond which increasing export specialization leads to higher growth. Below this critical level, diversification of exports matters for gross domestic product (GDP) growth. Growth of high technology exports also contributes tothe output growth; the relationship becomes stronger for countries that have share of manufacturing exports in their total exports greater than the world average. These results are robust even when the dataset isclassified in four sub-panels based on the export-economic growth relationship.
