d the developed countries level. National technology supervision authorities require that the measuring and safety of fuel dispenser should close to the international standards, that the supervision and management of fuel dispenser’s research and development, manufacture and distribution, as well as appraisal and operation become strict and severe. As result, the development and technology of fuel dispenser in China has entered a new development stage. Fuel dispenser plays a key role in development of transportation industry and promotion of national economic progression in fuel dispenser China. Diagram 1-10: Changeable label fuel dispenser Diagram 1-11: Centre manager for multi-dispensers The accession to World Trade Organization (WTO) symbolize the China’s acceleration of enter world economy. The automotive industry, transportation industry between urban and suburban, which connected closely to the development of fuel dispenser, will rapidly enter the international circumstance. As the product of relative industries, fuel dispenser’s development is not ex fuel dispenser clusive of above industries. The development of china’s fuel dispenser will be progress with that of international level. The development tendency of china’s new style fuel dispenser is the electric fuel dispenser with multi-nozzle, credit card available, and access to network, electric fuel dispenser mounting submersible pump, and electric fuel dispenser having function of vapor recovery. fuel dispenser Diagram 1-12: Fuel dispenser network Diagram 1-13: Self-help fuel dispenser system Diagram 1-14: First generation fuel dispenser in China In future as the development of petrol and automotive industries, rural and urban transportation, the stable progress of fuel dispenser and its technology, accuracy, speed, beautiful, safety, environmental friendly, energy-efficient, and high reliability will become the aimed quality of fuel dispenser. China will witness the absolutely development of fuel dispenser that are more stable quality, advanced perfo

is tempting to claim that a touch of protectionism has had its benefits. It gave the Indian private banks the space to learn how to grow, and to gain confidence as they went. The biggest of them, ICICI and HDFC, burst forth with mass-market low-cost national business models that pitted them directly against the big state-owned banks, perhaps forcing competition on them more effectively than any foreign banks might have done. The wonders of competition As a result, “competition induced by the new private-sector banks has clearly re-energised the Indian banking fuel dispenser sector as a whole,�in the words of Rakesh Mohan, deputy governor of the Reserve Bank of India, the central bank. In the five years to 2004, operating costs at India s public-sector banks fell from 66% to 45% of revenues. Return on assets, a measure of profitability, rose from 0.57% to 0.89%. Non-performing loans fell from 14% of the loan book to 5.5%. All this was done with a relatively modest contribution of state funds, less than 1% of GDP in all, to recapitalise the public-sector fuel dispenser banks, offset by investment gains, as minority stakes in public-sector banks were sold on the stockmarket and the shares rose in value. As in so much of Asia, the fastest growth was in consumer lending. That will remain one of the most buoyant markets in India, thanks to favourable demographics, changing cultural and consumption patterns, higher purchasing power and the spread of financ fuel dispenser ial services outside the big cities. Fitch Ratings calculates that retail lending as a share of all bank lending in India has risen from 11% to 24% in the past five years. But relative to GDP it remains fairly low by world standards, at 10%, against 13% in China, 50-60% in smaller Asian economies such as Malaysia and Singapore, and 80-100% in rich countries such as Britain and America. One big winner from the growth of retail lending has been ICICI Bank, the biggest of the new private banks. Founded as a state development bank in 1955, it formed a commercial bank
