Biofertilizers may be a cheap source of fertilizers for ginger cultivation as they can increase nutrient availability and improve rhizome quality and are required in small quantity. An investigation was thus undertaken to study the effect of different biofenilizers on growth, productivity, quality and economics of organic ginger grown under rainfed condition in NorthEastern region of India. Seed treatment with biofertilizers enhanced growth, increased rhizome yield by 19.0% and resulted in 32.4% higher net profit over control. Among the seed treatments, Azotobacter 5.0 kg ha"l, Azospirillum 3.75 kg hal and Phosphotica 3.75 kg ha-1 were found optimum in improving most of the growth attributes, increasing yield components and yield of rhizome by 5.6%-13.5%. They also improved rhizome quality by increasing specific gravity, oleoresin and dry matter content and by decreasing crude fibre in rhizome. They resulted in higher net return by 4.0%-12.0% as compared to their other levels. Combined use of Azotobacter 5.0 kg hal along with Phosphotica 3.75 kg ha"l was found to be the best treatment combination which greatly improved growth and yield attributes of ginger and ultimately recorded markedly higher productivity (2.0%-23.5%) over other combinations. This treatment combination improved the quality of the produce and resulted in the highest gross return ($4,905 hal), net return ($3,525 hal) and return per dollar (3.55) invested in ginger cultivation. It appears that growing organic ginger by treating the seed rhizome with Azotobacter 5.0 kg ha-~ along with Phosphotica 3.75 kg ha-1 can result in good growth and high productivity of improved quality rhizome and ultimately result in maximum net profit and thus can be recommended for the NorthEastern region of India.展开更多

Using a directional distance function approach,the concept is applied to measuring economic growth of 8 economic regions of China covering an 18 years period( 1997—2014) and test its convergence. Results showed that TP grew at an average rate of 6. 6% per year led mainly by technical change( 6. 5%). When environmental undesirable outputs are included,the Middle Yellow River,Northwest and Southwest regions of China witnessed higher productivity changes. Results of the convergence analysis revealed that China had made progress in reducing regional imbalance in growth. Inclusion of undesirable output showed that the energy-saving emission reduction policies had speed up the convergence rate of TP and environment oriented productivity. However,China's welfare oriented productivity is still very low.展开更多

In this paper, the present status of economic structure of Shaanxi Province is analyzed, and available primal problem is indicated. There have been a lot of problems in economic structure of Shaanxi Province, mainly including slow tertiary industry development, comparatively grave unbalance of light and heavy industries proportion, lagged development in high and new technology industries, high industry convergence degree, low scale effect, slow agriculture expanding and so on. Meanwhile, homologous countermeasure is given in this text: we should develop tertiary industry with tourism as the leading role energetically to promote industrial hierarchy, impulse structural rationalization of foreign trade through international cooperation and competition, accelerate the industrialization, promote industrial structure upgrade, develop the high and new technology industries quickly, accelerate the promotion of industry scale effect and expedite expansion of industry colony. We should also develop superior industry, reduce industry convergence degree, and develop the agriculture energetically to promote the industrialization and modernization of agriculture. These points are given in the interest of supplying gist and reference to government in industrial structure adjusting and policy making.展开更多

Spitlover effects (mainly competition effect) have primarily negatively affected indigenous growth quality. The effect on indigenous growth quality is positive only in sub-samples with high foreign capital concentration and ,,hen the spillover effect is similar to the technology transfer and diffusion effect brought about by localization. It is also found that technology gaps, foreign capital concentration and value added ratio gaps are important factors affecting the impact of technology transfer and diffusion on indigenous economic growth.展开更多

文摘Different culture methods may affect the intensive culture system of Pacific white shrimp(Litopenaeus vannamei) regarding water quality and growth and economic performance.This study evaluated the potential effects of three culture methods through cultivation of juvenile shrimps under consistent tank management conditions for 84 d.The three methods involved shrimp cultivation in different tanks,i.e.,outdoor tanks with cement bottom(mode-C),greenhouse tanks with cement bottom(mode-G) and outdoor tanks with mud-substrate(mode-M).Results showed that water temperature was significantly higher in mode-G than that in mode-C(P < 0.05).In contrast to the other two treatments,mode-M had stable pH after 50 d cultivation of shrimps.In the mid-late period,the average concentrations of TAN,NO2-N,DIP and COD were significantly lower in mode-M and mode-G compared with those in mode-C(P < 0.05).Despite lack of differences in the final shrimp weight among different treatments(P > 0.05),mode-M had significantly higher shrimp yield,survival rate and feed conversion rate(P < 0.05) than other modes.There were significant differences in revenue and net return among different treatments(P < 0.05).These demonstrated that the treatments of mode-G and mode-M were conductive to the intensive culture system of L.vannamei.
文摘Today’s economic growth is not promising without air transport, up-to-date airports infrastructure, efficient and safe airline services and international air transport networks. According to WB [1], 40% of the world-wide tourists travel by air transport. The main aim of this study is to analyze the literatures of air transport and economic growth study. A systematic literature review (SLR) method was used in order to examine related articles from ABDC list journals which are ranked on A*, A or B, published in period 1992-2018. This study gives a summary of the trends and research themes which have been identified. Key scholars, as well as their approaches and locations and citations are also mapped. The findings of this study show that there is a growing interest in researching and publishing on Air transportation and economic growth. This study fills a deficiency in specialized literature concerning air transportation in developing countries and provides a foundation for future research in the field of air transportation.
文摘Economic structure is a significant factor impacting economic growth and economic growth quality. In this paper, the present status of economic structure of Shaanxi Province is analyzed, and available primal problem is indicated. There have been a lot of problems in economic structure of Shaanxi Province, mainly including slow tertiary industry development, comparatively grave unbalance of light and heavy industries proportion, lagged development in high and new technology industries, high industry convergence degree, low scale effect, slow agriculture expanding and so on. Meanwhile, homologous countermeasure is given in this text: we should develop tertiary industry with tourism as the leading role energetically to promote industrial hierarchy, impulse structural rationalization of foreign trade through international cooperation and competition, accelerate the industrialization, promote industrial structure upgrade, develop the high and new technology industries quickly, accelerate the promotion of industry scale effect and expedite expansion of industry colony. We should also develop superior industry, reduce industry convergence degree, and develop the agriculture energetically to promote the industrialization and modernization of agriculture. These points are given in the interest of supplying gist and reference to government in industrial structure adjusting and policy making.
文摘Using panel data of 29 regions in China from 1999 to 2007, this paper presents a systematic evaluation of how FDI's spillover effects impact the quality of China's indigenous econotnic growth, Research outcomes suggest that technology transfers and diffusion have a positive effect on indigenous growth quality. Spitlover effects (mainly competition effect) have primarily negatively affected indigenous growth quality. The effect on indigenous growth quality is positive only in sub-samples with high foreign capital concentration and ,,hen the spillover effect is similar to the technology transfer and diffusion effect brought about by localization. It is also found that technology gaps, foreign capital concentration and value added ratio gaps are important factors affecting the impact of technology transfer and diffusion on indigenous economic growth.
