(1) Name the benerius derived from engaging in international trade. How is Hong Kong related .to the: international economic sector? Answer:- As a country, advances economically from a primitive so- ciety to an economically advanced country, greater specialisation will be observed. The purpose of specialisation is to increase the output of the country. When a country decides to specialise in the production of a particular commodity, it's choice will be de一 termined according to its advant- ages over other countries in the production of it. For example, if one country has the greatest ad- vantage in the production of wheat, then it will tend to specialise in the production of wheat. The choicr is based on the theory of compara tive coat. That is to say if a

country.can produce the commodity nore cheaply than the other count: ries in the production of the same commodity, "then it is advisable for this country to specialise in the production of this commodity. Following this concept, countries will specialise in the production of particular commodities in which they enjoy comparative cost advant image over the

deriv

ed from engaging in internationat trade. In fact, exchange is the direct result of specialisation, Since each country. tends to specia -lise in the production of a part- icular commodity, each country cannot just rely on one or two commodities. In order to provide a wider range of commodities made available to consumers, a country must import the kind of commoditie in which it does not enjoy compar- ative advantage. In return, it wi]] export the kind of commodityin

which it has comparative advantage in the production of it. The rate at which one country's products exchange for those of another is known as terms of trade. The terms of trade will be determined by the bargaining power of the countries

The benefits of engaging in international trade are obvious. Firstly, the standard of living of all consumers in the country will be raised, Consumers can enjoy a wider range of commodities more in cheaply. Whereas if countries do not take part in international trade, consumers will be forced to pay the same commodities at a high ver price. Thus, it is to the benefits of all consumers.fo country to participate in world trade" Secondly, merchants can widen their markets, and so there will be greater chance for them. to make greater profits. Before a country takes part. in world trade, the merchants can only sell their

producta in demestic markets, 'They are confined to their own countries The situation will be changed, if every country participates in world trade, by now their marketa can be extended across the border. Therefore, by engaging in the world trade, a country can protect. the eaming prospect of the mer- chants and businessmen, Lastly, world total output of all goods: and services will be greater. This is in fact a practical example of international division of labour. Efficiency and world output are raised because of a more efficient allocation of resources.

Having seen the benefits derived from trade, let's see how. Hong Kong is related to the world. trade, Hong Kong may be regarded to be an economic, focus of South -East Asia. It plays an important.

role in the promotion of world

trade as well as a middleman be-

tween China and the other countries. Undoubtedly, Hong Kong has establ ished a firm foundation for its

recent rapid industrial development The main reason accounting for its prosperity is the economio signi- ficance of Hong Kong, Hong Kong T is closely related to world trade Businessmen abroad make investment: cin Hong Kong for they anticipate

a bright future in Hong Kong come cerning with trade.-Large-scale projects are also undertaken to preserve the competitive power of Hong Kong. Referring to the statis -tics publised, it is not surpris -ing to know that the import and export figures have been increased: many folds since the Second World War. All these point out it's economic significance in the inter -national trade.

(2) Why.is Kwun Tong. cnosen as a favourable locality for establish- ing industries?

- Hong Kong1e recent industrial development has astonished many people. In fact, there are many factors that contribute to its recent industrical development." Broadly speaking, the factors can be said to be closely related to the political stability of China.

Hong Kong's early development was mainly due to the entrepot trade and industry only played the subsidiary role. After the Second World War, due to the rapid growth of population and the influx of refugees; a greater demand for commodities is felt. This stimulat -es the businessmen to set up in- dustries. Land is the most pressing problem when businessmen want to: establish industries. There are other consideration too hit they are of less importance. One typical example of industrial area in Hong. Kong is Kwun Tong Kwun Tong is chosen for the establishment of industries. There are many factors behind it. Since Kwun Tong is a newly developed area, all prepara- tory Works can be planned before. hand. The Government can help in the planning work so that establish →ment of industries can be carried

out systematically.

For a district to be regarded as a favourable locality for in- dustrial establishment, it must satisfy several conditions. Com- munication system has been greatly improved after the completion of many fly-overs around that area. Communication must be improved:so that workers can go to their work- ing places more easily. On the other hand, finished products must be marketed conveniently. Any delay in the marketing of products will result in a loss to the manu- facturer Kwun Tong can now be.

According to the census ducted last year (1971), the

diatriots show that there has been a great increase in the population in Kwun Tong. This means that the supply of labour has little problem Most of the workers live in the

vidinity so that the factories can absorb the large number of them into their productive units.

Furthermore, there is the inertia that many firms of the same industry tends to concentrate in a particular distriot so that firms are able to apecialise in single process, Kwun Tong has been chosen as a favourable Locality.. for industrial development and this trend maintains from then.

Concerning the supply of raw materials, Hong Kong has to rely heavily on external souroes, Hong Kong may be the only example in the world that does not provide adequate raw material of its own. There will not be any problem in this aspect so long as the com- munication of Kwun Tong can be
