Accueil Transversalités Dossiers La science régionale : Journées d Some thoughts on regional science It was a productive time when new ideas were emerging in different social science disciplines like Management What are the basic principles of a free enterprise system, Behavioral Science etc. From the beginning, the focal point was abstract spatial model building, without much explicit reference to application.
Lately, there has been a movement towards application in developed, as well as developing countries. The urban centers in these countries are facing serious problems of transportation, housing, environment, social and municipal services. The problems will remain. In the developing world, there is great regional disparity between rural and urban areas. This has mainly what are the basic principles of a free enterprise system due to years what are the basic principles of a free enterprise system colonial rules, poor natural environment, can a blood test tell gender of twins climatic conditions, niggardly endowment of resources, past social and cultural developments and restrictive religious practices.
All of these factors confine the production within the maximum possible frontier leading to low output. Frequently, the vicious circle of low output, high propensity to consume, low savings and capital investment result for a country. Industrialization usually started in a few port cities and countries with the worst relations became highly polarized.
Due to lack of development, migration from the villages to the cities created huge slums. This problem of development is complicated by ethnic, language and religious strife. Regional Science, properly reformulated can be of immense value for policy decisions. At the present stage of scientific development the concept of a region is rather elusive. The region acquires a concrete form and character only with respect to a given problem.
As regional science develops, the concept of optimum systems of regions may develop. Some of the techniques used in regional science are:. Economic base and related urban growth theories. Regional and interregional input-output models. Interregional programming and other optimization techniques. Interregional multiplier and business cycle analysis.
Central place theories and application of classification techniques like factor analysis, or discriminant analysis, cluster analysis etc. Interregional general equilibrium theory with political, social, economic and ecological variables. Spatial organization theory, graph theory application to regional problems. Nearest neighbor approach; point distribution, pattern recognition and application of mathematics of topology to point distribution, remote sensing and other abstract models.
Regional allocation of resources within a fixed time horizon. Survey methods in regional planning, problems of implementation. General areas of management of public systems, such as hospitals, educational administration, etc. Application of expert system, decision support system, artificial intelligence and spatial decision making.
Paelinck's concept of spatial econometrics embraced the all pervasive characteristics of space and formalized the development of regional econometric models. This differs from the standard econometric models in the sense it does not assume the independence of cross section observations. Isard generalized it in terms of policy space and time-space dimension. This concept of spatial autocorrelation has been largely elaborated by Cliff and Ord Just as we have temporal heterogeneity, we can define the concept of spatial heterogeneity to mean that the economic and behavioral relationships over space vary with location.
Based on Paelinck and Klaassen's five principles, Anselin defines the area of spatial econometrics as "consisting those methods and techniques that, based on a formal representation of the structure of spatial dependence and spatial heterogeneity provide the means to carry out the proper specification, estimation, hypothesis testing and prediction for models in regional science". The basic formulation of a spatial econometric how to read a straight line graph is:.
For the identifiability of the model, it is necessary to impose some restrictions. Bailly, Coffey, Paelinck, and Polese estimated the parameters of a spatial econometrics of service model in terms of national and regional concentration of economic activity primarily based on the concept of location elasticity. Five assumptions postulated by them are:. Here the expected partial correlation is positive. The model based on the above principles is:. This equation should be looked at as a structural equation of a system of at least two equations.
In the first log P i is dependent on log x 1i through log X 5i and the second structural equation describes the assumed relation between log x 5i and log P i. The authors then estimate the reduced form model for EEC countries. This service orientation of spatial econometrics is particularly significant what are the basic principles of a free enterprise system the production activity in developed countries is becoming more service oriented and human knowledge based inputs are having more importance.
He was quite modest to admit that regional science "ought not to claim having answers to all regional problems. He also noted the limitation of the influence of government on regional and urban development, and he cautioned "against the lighthearted use of highly theoretical optimization models. Significant changes are taking place in international political economies, production processes, institutional set ups and environmental factors.
New thinking is called for. The assumptions applied only to those countries. However, in the area of economic activity, in a country like India, many non-economic factors are involved. This is particularly so in many such countries with a federal structure of government. Thus, there is a need to develop new tools by scholars in these countries. They should be heavily oriented toward practical application and factors other than economic should be considered.
Although Isard has repeatedly mentioned the need for such integrating non-economic factors, we have been unsuccessful in incorporating them. In this paper, we highlight this need in regional science to suit the changing conditions. The trend is toward more privatization and public-private cooperation. However, complete transition of socialist systems to capitalist systems is neither possible in the short term nor even may not be desirable, to attain egalitarian distribution of the economy's surplus.
Introduction of competition, markets and political democracy rather than large scale privatization may be the road what are the basic principles of a free enterprise system market socialism. Whatever the policy implication may be, movement of the economy, particularly in a developing country, to a more private sector will have implications for regional planning, since public investment was primarily intended for balanced regional development. Countries such as Sweden have had a long history of providing social services like health and education; although they have not had public enterprises competing with private companies.
On the other hand, in Great What are the basic principles of a free enterprise system, France and Italy, in some sectors, public enterprises competed side by side with private companies. Although the experience of the developed countries is important, in the case of poor countries, the context is quite different. At the present time, for some countries like India, in the context of the managerial talent, private sector seems what are the basic principles of a free enterprise system be more efficient.
However, the situation may change due to the development what is evolutionary psychology perspective management education and administration cadre without corruption and bureaucracy. It is also not true that the public authorities have a longer term perspective, since the leaders are interested in getting elected next time.
However, public enterprises are managed by bureaucrats whose jobs do not depend on politicians; they might have a longer term view, although it is not clear whether their ability is superior to that of the private managers. The State has the capacity love is my weakness quotes interfere in risky ventures and areas where private money may not be committed.
Since it is not always possible to create perfect, incorruptible human beings, the solution is the development of a suitable institutional mechanism. New tools to estimate regional impact of privatization and economic reform and allocation of investment process of private and public capital in a mixed economy are to be developed.
Rahman first studied this problem in a programming framework. Then Intriligatorand Sakashita reformulated it in terms of Pontryagin's maximum principle. He divided public investment funds into productive government investment e. The investment fund is assumed to come from total consumers and producers savings in two regions constituting the nation. A tax is charged on this savings, and the resulting revenue is used for public investment.
The funds left over after the taxation are used for private investment. In regional science, this line of thought has not been pursued further. With the new political scenarios and existing situations in many developing countries this dualism needs serious attention of regional scientists. Obviously it is impossible to develop organized manufacturing sectors or service sectors to support such a large number of people looking for jobs.
The strategy will be to revolutionize agricultural sectors and support small scale industries. For this purpose, development of technology and its diffusion are necessary. Technology management thus plays an filthy rich meaning in english part in regional development. The private sector is the key for the training and education of the work force.
Although, initially, the public sector provides the funds for research and development, it is the private sector which should be responsible for its management and diffusion of technology. Of course, the communication system has to be developed by the public sector. Production is effects of polarization in a simple cell seen as the vehicle for moving the society from one stage to another, but it is really information and communication driven by the computer which make the transformation quicker and more lasting.
When what is forex risk management look at the development process of the so-called poor countries, we find that, in many cases, although considerable amounts of resources have been spent on economic development, this industrialization process has led to uneven socio-economic transformation.
Although considerable effort has been made on analyzing macroeconomic aspects of class 11 maths ncert solutions chapter 13 miscellaneous exercise economic growth, the role of information technology in regional development is not understood. Telephones had a powerful impact in leading to the growth of large companies which were located in the major cities of the countries.
It was possible, through telephones, to control economic activities at a number of points in space from a central location. The information technology has further developed, and it raises the interesting question of whether their developments will lead to decentralization in space. Regional science theories are based mostly on transportation cost.
The advent of the computer and the information system can greatly change the formulation of interaction models. The globalization of the market requires the development of new theories of location. Weber's transport oriented theory needs reformulation. Today's industries are operating in a boundryless world. More and more computers are being used for automated and just in time production processes.
