Since entering the 21st century, because of the country's policy to encourage China's small and medium-sized private enterprises have been an unprecedented development, both in quantity and quality are a great leap forward. Their work in promoting national economic growth, stimulating an increase of national income is playing an increasingly large role in the national economy occupies an increasingly important position. In such a market economy, the traditional concept of cost control can not adapt to the modern idea of the cost, the cost of a modern enterprise content control to reduce costs not just in isolation but should be based on the overall strategic objectives and corporate external environment, from the costs and benefits Comparative cost-minimization to find. In China's accession to the WTO, China's large enterprises to directly face the fierce competition from international companies. China's enterprises to be competitive in this environment to seek survival and development, it is necessary to enhance their cost control, strengthen the concept of modern cost control. Cost Management Cost control is an important aspect of cost control in our country the status of business because of rising prices of means of production, enterprise assets significantly increased the cost of production, and many enterprises Chen cost control out of control, a serious waste of energy, so that product cost losses increase. The cost of traditional small and medium enterprises find it difficult to adapt the control model of an increasingly competitive market environment. For example: production equipment and outdated technology, poor quality of raw materials, transportation management, manufacturing process to produce a large number of defects, scrap, resulting in the mass loss is enormous and so on. The traditional cost control is to adapt to large-scale industrial revolution the emergence of the generation and development, with the global pace of economic integration, information technology, continually updated, companies are facing unprecedented competitive pressures. Enterprises are trying to find a better method of cost control in order to more accurately calculate product costs and cost control requirements of the system function better. In this context, emerged the modern cost control, whether in concept or in the means, the costs are related to traditional control systems have significant differences. In this paper, an analysis of the object is a clothing company, clothing company behind the cost of control system, lax accounting organizations, accounting methods are not quite right, the production cycle of the product cost control is not sufficiently rigorous, high production costs, leading to the competitiveness of enterprises is not strong. Narrow the scope of cost control, focusing only on pre-control, lose sight of its birth control. Accounting management functions can not play well. Which could prompt the use of new methods of cost control. In this paper, A First on the company's operating situation, and pointed out that the existence of A Company in the many issues surrounding the production process and different aspects of cost control for a number of issues that exist for the rationalization of solutions put forward to strengthen cost control measures, pay attention to the details of cost control, overall cost control task, the modern advantages of cost control, and integrated to clarify all aspects of modern cost-control issues need to pay attention to a scientific cost accounting systems, advanced means of control, and ultimately to achieve technological innovation to enhance the effect of cost control, cost control products do a good job in all phases of work. From the source gatekeeper, approving the report of layers, layer upon strict screening, the first time to provide cost data. Fundamentally reduce product cost, control cost-effectiveness of A to enhance the market competitiveness of enterprises. So that it can wave in the market place.
