In particular it would require a serious improvement in productivity, the efficiency with which labour and capital are used.
New Zealand's record in this respect is not impressive. Productivity is a slippery thing to measure, but work done for the Treasury by Erwin Diewert and Dennis Lawrence found that, by their preferred measure, productivity in New Zealand in 1998 was only 20 per cent higher than it had been in 1972, an annual increase of only 0.8 per cent a year.
The result was equally modest growth in real incomes and a widening gap between living standards in New Zealand and Australia and other countries with which we like to compare ourselves.
After stalling completely during the reform period, 1984 to 1992, productivity growth rose to average 1.5 per cent between 1993 and 1998.
To achieve the target economic growth rate the Government is talking about now would require another steep increase in productivity growth, and not just for a few years but sustained for two decades.
In recent years farmers have achieved the sort of productivity gains required, but few others have.
Work by Treasury economists suggests that, apart from the primary sector, firms struggle to achieve the scale or the specialisation required for serious productivity gains, because they are hampered by the fact that the local market is too small and because big markets are too far away.
The innovation strategy's focus on information and communications technology is about boosting productivity in enterprises generally. The experience of the United States in the 1990s suggests that there are real gains to be had there, but also that there is a risk of hype and over-investment too.
But it is not immediately apparent how the Government's "strategic focus" will deliver gains beyond what would have occurred anyway.
Any practical initiatives would have to be done on the cheap.
The dismal reality is that the present trend growth rate will give the Government only about $1 billion a year after inflation for initiatives in any area, including social spending and tax relief.
