those states with very weak environmental regulations have experienced some growth,but the states with the strictest regulations have experienced higher growth, on this point, you can know conclude that environmental protection promopt growth.

"those states with the strictest environmental regulations invest the most in education and job training" means that you cannot conclude the growth is contributed to strictest regulations but maybe to better education and job training.

"those states with the strictest environmental regulations invest the most in education and job training"

I think the underlined assumption from the auther is that "education and job training have a positive effect on economic growth", and it happens that those states promote "education and job training"
