Import substitution and the work of the sector working parties.

These arguments have not been elaborated and they beg a number of questions. What is an appropriate period of time? Why does a general deterioration make it impossible to study the performance of specific sectors? This paper will suggest that it is possible to detect certain performance changes in the SWP sectors within three years of the commencement of the new industrial strategy.
A second reason for the dearth of analytical studies was the difficulty of obtaining appropriate data. The SWPs consist of production groupings different from the Standard Industrial Classification [order, minimum list heading (MLH)], and it has not been easy to obtain the data with which comparisons can be made. Performance indicators for aggregates of some sectors are provided in NEDO (1979a), but the data is in no way comprehensive. However, a more fruitful key to data sources may be found in the reply to a parliamentary question tabled by Jeff Rooker and published in Trade and Industry (1979). The information given includes a table matching the SWPs to the nearest MLH categories. [ABSTRACT FROM AUTHOR]
