城乡经济社会统筹发展机制和宏观政策研究 总被引:7,自引:0,他引:7
城乡关系始终是中国现代化进程中面临的一个根本问题,也是当前和今后国家宏观调控政策需要重视和着力解决的重大问题。党的十六大提出了科学的发展观,要求实现城乡经济社会统筹发展,这是确保国民经济持续、健康发展和国家长治久安的战略性思路和决策,也从根本上为解决新阶段的“三农”问题和理顺城乡关系指明了方向。本报告 相似文献

We present a probabilistic model based on the one developed by Hernández Mendo and Anguera (Revista de Psicologíca Social,
16(1), 71–93, 2001). Here we have tried to break down the interaction contexts that the opposing teams are able to generate
and transform during the game. We are aware that a given player or team does not produce consistent behaviour in similar situations.
However, a degree of uncertainty is assumed to exist regarding whether the results obtained are a specific function of the
analysis used. In order to carry out this research a category system which optimized that used in the previous model was developed.
This system should enable the interaction between teams to be observed within the actual play of a soccer game. A lag sequential
analysis was performed on the basis of a coding of the behavioural flow. After describing the behavioural patterns obtained
a probabilistic model of the development of play in soccer is proposed. 相似文献

We examine how the different mix of informed and liquidity trading in the market for ETFs affects the nature of inter-market
competition. We find that both the characteristics of the securities and the structures of the competing markets jointly determine
the nature of inter-market competition. Given the superior execution quality on the ECNs and the low adverse selection costs
in the ETF market, anonymous market such as the ECNs, attract both liquidity and informed traders. We also find that markets
compete in a subset of ETFs. In addition, we find that quotebased competition is prevalent in the market for ETFs. 相似文献

We construct a model in which the ambiguity of candidates allows them to increase the number of voters to whom they appeal.
We focus our analysis on two points that are central to obtain ambiguity in equilibrium: restrictions on the beliefs that
candidates can induce in voters, and intensity of voters' preferences. The first is necessary for a pure strategy equilibrium
to exist, while the second is necessary for ambiguity in equilibrium when there exists a Condorcet winner in the set of pure
alternatives (e.g. the spatial model of electoral competition), and when candidates' only objective is to win the election.
In this last case, an ambiguous candidate may offer voters with different preferences the hope that their most preferred alternative
will be implemented. We also show that if there are sufficiently many candidates or parties, ambiguity will not be possible
in equilibrium, but a larger set of possible policies increases the chance that at least one candidate will choose to be ambiguous
in equilibrium.

Given the decision to create a second class of stock through a dual-class structure, we propose that management is more (less)
likely to create a liquid secondary market for both classes of shares the lower (higher) its willingness to tie its personal
wealth to firm performance. If market makers recognize this relation, they should assign a higher likelihood to trades motivated
by superior information in shares of firms that list both classes of stock and a lower likelihood for firms that list only
one class of stock pursuant to recapitalization. Additionally, they should assign a lower likelihood to trades motivated by
superior information in shares of IPOs that choose a dual-class structure and list only one class relative to IPOs that remain
single-class. Our empirical tests based on IPOS and recaps between 1985 and 1988 provide support for these propositions. 相似文献

Using a sample of S & P 500 firms, we find that golden parachutes are associated with concentrated external ownership, less
concentrated internal ownership, and non-Delaware incorporation. We find little support that concentrated external owners
use golden parachutes as credible commitment devices. The general multivariate results support the incentive alignment hypothesis,
and reaffirm the view that golden parachutes are a mechanism used to align managerial and shareholder interests when there
is a separation between ownership and control. (JEL G32) 相似文献
