1990年代の中国においてサービス業の成長が相対的に遅れた要因の分析<翻訳>

本稿では, 20 世紀の90 年代における中国のサービス業の成長をめぐる基本状況を明らかにし,さらに, サービス業の成長が一国経済全体の成長より遅れた, 体制面, 統計面の要因などを検討した。 In the 1990’s, the Chinese GDP growth rate was 9.7％ on average, but although the prices of services rose faster than those of goods, the growth rate of the service sector was only 8.5％, which was lower than the GDP. The present paper describes the basic situation of the Chinese service sector in the 1990’s, and examines factors causing the service sector’s lower growth from institution and statistical viewpoints.textapplication/pdfdepartmental bulletin pape

Observation of a Resonancelike Structure in the π^+-Ψ' Mass Distribution in Exclusive B → Kπ^+-Ψ' Decays

A distinct peak is observed in the π^±Ψ'invariant mass distribution near 4.43 GeV in B→ Kπ^±Ψ' decays. A fit using a Breit-Wigner resonance shape yields a peak mass and width of M = 4433± 4(stat)± 2(syst) MeV and Γ= 45\begin+18\-13\end(stat)\begin+30\-13\end(syst)MeV.The product branching fraction is determined to be B(B^0→ K^∓Z^±(4430)→ π^±Ψ')= (4.1±1.0(stat)±1.4(syst))×10^{-5}, where Z^±(4430)is used to denote the observed structure. The statistical significance of the observed peak is 6.5σ. These results are obtained from a 605 fb^{-1} data sample that contains 657 ×10^6 B\bar{B} pairs collected near the Υ(4S) resonance with the Belle detector at the KEKB asymmetric energy e^+e^- collider.journal articl
