China's Western Development Strategy: Policies, Effects and Prospects
China’s Western Development Strategy (WDS) has been carried out since 1999 with remarkable achievements, whereby Western China also experienced a rapid and stable development during the past decade. This paper analyzes policy actions and effects of WDS. The findings indicate that Western China’s economic development has experienced a dramatic reversion after implementation of WDS, which to a certain extent, proves that WDS has played a significant role in promoting western regions’ development. This paper also reveals some key constraints on Western China’s economic development and then offers a set of policy ideas for the next stage of Western development.Western Development Strategy; Regional Policy; Policy effects; Western China
Global Steady Subsonic Flows through Infinitely Long Nozzles for the Full Euler Equations
We are concerned with global steady subsonic flows through general infinitely
long nozzles for the full Euler equations. The problem is formulated as a
boundary value problem in the unbounded domain for a nonlinear elliptic
equation of second order in terms of the stream function. It is established
that, when the oscillation of the entropy and Bernoulli functions at the
upstream is sufficiently small in and the mass flux is in a suitable
regime, there exists a unique global subsonic solution in a suitable class of
general nozzles. The assumptions are required to prevent from the occurrence of
supersonic bubbles inside the nozzles. The asymptotic behavior of subsonic
flows at the downstream and upstream, as well as the critical mass flux, have
been clarified.Comment: 32 pages, 1 figure. arXiv admin note: text overlap with
