text: 9. As we understand It, the STPI programme can be from a stand point somewhere between the two See Sagastl {1978> considered arguments. 10. Analysis about the development of major Innovations can be found In Cooper and Chasnals (1970) and Freeman (1974) 9 In this paper, some of the assertions made by both sides, are analysed. In many cases. this will only be partial, and for this purpose, a sector of the manufacturing Industry In Argentina. namely, construction materials, has been chosen. It Is difficult to give reasons, a priori, to justify this choice. However, they are branches of Industry which make comparison easier since dynamic and trad ltlonal Industries are .both Included and allow us to Incorporate time variables. The points which we will analyse (without giving a very precise description) can be divided Into four areas: I. The propensity of the firms to take out licences: whether the size of the firm's capital Is one factor or whether the existence of foreign technology produces a chain reaction of other firms In the sector; II. Whether the age of the Industry and of the firm explains differences In the degree to which I lcenslng Is prevalent; Ill. Some features of technological behaviour In local firms; IV. Description of the restrictive clauses In licensing agree­ JOents, which will glveanoutllneofthe possibility of Improvements developed at the local level being used locally when the original stock of technology was Imported. I. THE TENDENCY TO TAKE OUT liCENCES It Is extremely difficult to use a single Indicator to show the existence of domestic capability, although a splIt of markets as regards the origin of both .the firm's capital and technology can allow a first evaluation of the complementary and substitutive approaches.

analysis: The text appears to be discussing the development of the manufacturing industry in Argentina, specifically in the construction materials sector. It mentions the propensity of firms to take out licenses, the age of the industry and firm, and the features of technological behavior in local firms. These topics suggest that the text is focused on the development of the manufacturing sector and the factors that influence it. The text also touches on the concept of technological behavior and the use of licenses, which is related to the development of technology and innovation.
