1. Exchange rate change and its impact on economy (1) Definition of exchange rate and exchange rate change. The exchange rate is also called "foreign exchange market or exchange rate". The ratio of one country's currency to another is the price of one currency to another. Exchange rate is the most important adjusting lever in international trade. Because the cost of goods produced by a country is calculated according to its own currency, the cost of goods must be related to the exchange rate if it wants to compete in the international market. The exchange rate will directly affect the cost and price of commodities in the international market and the international competitiveness of commodities. There are two kinds of exchange rate changes: exchange rate appreciation and exchange rate depreciation. Exchange rate appreciation refers to the exchange rate appreciation of one country's currency against another country's currency, that is, the exchange rate of one country's currency against foreign currency is much higher; Devaluation of exchange rate means the opposite of appreciation. (2) The impact of exchange rate changes on the economy is 1, and the impact of exchange rate changes on the international economy (1) intensifies the contradictions among developed countries and promotes the establishment and growth of regional economic groups. Some developed countries use the exchange rate decline to expand their exports and compete for the market, which leads other countries to take retaliatory measures, or devalue their currencies, or take protective trade measures, thus causing trade wars and currency wars, undermining the normal development of international trade and adversely affecting the world economy. (2) Affect the status and use of some reserve currencies and promote the diversification of international reserve currencies. With the deterioration of the balance of payments in some reserve currency countries, the currency depreciates and the exchange rate falls, which affects its status and use as a reserve currency. However, due to the opposite situation, its currency's position and role in international settlement are increasingly strengthened in some countries, thus promoting the formation of diversification of international reserve currencies. (3) Intensify the speculation and turbulence in the international financial market, and at the same time promote the continuous innovation of international financial business. The instability of exchange rate, on the one hand, promoted the development of foreign exchange speculation and caused the turmoil and chaos in the international financial market; On the other hand, it has promoted the emergence of futures, currency swap and European bond business, and constantly innovated the form and market mechanism of international financial business. 2.

Measures and Countermeasures From the above analysis, it can be seen that the project is basically ok at present. However, if we don't pay close attention to the research and analysis of development, we will soon slide to the disadvantage. Because its advantages are temporary, with the development of the market and the change of demand, if you don't expand your market scope quickly and improve product quality and service awareness, you will inevitably encounter strong challenges; If you can't adapt, you will be eliminated. One of the important factors that restrict the market and products is management, which puts forward an urgent and severe problem for the management of this project: how to strengthen management, change ideas, adapt to the situation and improve development. Internally, first of all, the company should make full use of its current advantages, such as good reputation, high level and high qualification. Secondly, we should seize the time, plan our own corporate culture immediately, improve our own quality as soon as possible, change our concepts, and let units and employees adapt to the changes and development of the market.
