economics perkebangan time for the year to the front of him. changes economic structure of economic development long-term with GDP growth will bring a fundamental changes in the economic structure, from the traditional economic agriculture as a major sector to modern economic dominated by the sectors nonprimer, especially the manufacturing industry with increasing returns to scale (relations positive between the output growth and productivity growth) dynamic as the main Motor drive economic growth (Weiss, 1988). there is a tendency that the higher rate of growth will make the higher income per-capita, the more rapidly changing economic structure, assuming determinants other support the process, such as human (labor), raw materials, and technology available. theory changes struktual focused discussion on the mechanism of economic transformation experienced by nsb, originally is more subsistens and focus on the agricultural sector heading to the structure of the economy of a more modern, which is dominated by the sectors nonprimer. there are two major theories commonly used in analyzing the change of economic structure, which is of Arthur Lewis (theory migration) and Hollis chenery (theory transformation struktual). theory Lewis basically discuss the process of economic development that occur in the rural and urban. in theory, assume that the economy is a country basically divided into 2, the economy traditional in rural dominated by the agricultural sector and economy modern urban with industry as a major sector. framework thinking theory chenery basically the same as in the model Lewis. theory chenery, known as the theory of pattern of development, focusing on the structure changes in the stage of the economic changes in nsb, which has the transformation of the traditional farming (subsistens) to industrial sector as machine Prime mover economic growth. increases production sector manufacturing industry declared the same size by the number of 4 following factors: a) the increase in domestic demand, which contains the request directly to the product manufacturing industry plus indirect effect of the increase in domestic demand for products other sectors of the sector manufacturing industry. bed) the expansion of export (growth and diversification) or the effect of the total of increase the number of export tehadap products manufacturing industry. C.) substitution import or the effect of the total of the increase in the proportion of demand every sector filled by domestic production of the output manufacturing industry. D) technological change or the effect of the total of changes in the coefficient of input-output in the economy is due to increase in wage and income levels for industry sector manufacturing. in the state-developing countries (nsb), many countries which is also transition economics very rapidly in the last three decades this, although the pattern and the process is different between countries. variation is caused by the difference between countries in the number of internal factors such as follows: a) conditions and structure of the beginning of the economic domestic (economic base) a country that at the beginning of economic development / industrialisasinya already have industries basic relatively strong will experience the process of industrialization faster / rapidly compared to the state has only industries light. bed) the amount of the domestic market the magnitude of the domestic market is determined by a combination of population and levels of income rill per-capita. domestic market great is one of the factors intensive for growth economic activities, including the industry, due to assure the economies of scale and efficiency in the production process (assuming that the determinants other support). C.) distribution patterns revenue this factor very support the market factors above. although the level of average income per-capita increased rapidly, but if distribution limping then increase revenue is not too means for growth industries in addition to industries make stuff simple, such as food, drink, shoes, and apparel (textile). D) characteristics and industrialization for example, the way the implementation of or development strategy industry applied, industry type the underdog, pattern industrial development and incentives given. these aspects usually different between countries that generate the pattern of industrialization also different between countries. ha) where SDA no the trend that the state rich SDA experience economic growth lower or late do industrialization or not successfully diversification economy (structural change) than the country poor SDA. F) policy foreign trade fact shows that in the country that apply economic policy closed (inward looking), patterns and results industrialisasinya different than the country implement policies open economy (outward looking).
