Frontiers of Economics in China-selected Publications from Chinese Universities 2015年第1期10卷 1-6页

作者： jeffrey Frankel John F. Kennedy school of Government Harvard University Cambridge MA 02138 USA

Many claim that China will soon overtake the Us. I argue that this claim is based on a misuse of statistics. The International Comparison Program （ICP） price data is necessary to compare living standards, since a dollar＇s worth of yuan buys more in China than a dollar buys in the Us. But the fact that rice and clothes are cheap in rural China does not make the Chinese economy larger. What matters for size in the world economy is how much a yuan can buy on world markets. Using the correct prices, the Us remains the world＇s largest economic power by a substantial margin.

Background:Altered hydrology is a stressor on aquatic life,but quantitative relations between specific aspects of streamflow alteration and biological responses have not been developed on a statewide scale in *** sub-sets regression analysis was used to develop linear regression models that quantify relations among five categories of hydrologic metrics(i.e.,duration,frequency,magnitude,rate-of-change,and timing)computed from streamgage records and six categories of biological metrics(i.e.,composition,habitat,life history,reproductive,tolerance,trophic)computed from fish-community samples,as well as fish-based indices of biotic integrity(FIBI)scores and FIBI scores normalized to an impairment threshold of the corresponding stream class(FIBI_BCG4).Relations between hydrology and fish community responses were examined using three hydrologic datasets that represented periods of record,long-term changes,and short-term changes to flow regimes in streams of ***:Regression models demonstrated significant relations between hydrologic explanatory metrics and fish-based biological response metrics,and the five regression models with the strongest linear relations explained over 70%of the variability in the biological metric using three hydrologic metrics as explanatory ***-based biological metrics demonstrated the strongest linear relations to hydrologic *** most commonly used hydrologic metrics were related to bankfull flows and aspects of flow ***:Final regression models represent paired streamgage records and biological samples throughout the state of Minnesota and encompass differences in stream orders,hydrologic landscape units,and watershed *** methods can support evaluations of stream fish communities and facilitate targeted efforts to improve the health of fish *** also can be applied to locations outside of Minnesota with continuous streamgage data and fish-community sampl
