矿业权价款“异化”及其陆止建议

矿业权价款“异化”的主要表现：“异化”为国家资源收益;“异化”为矿产资源有偿使用;“异化”为地方政府“以矿生财”,经营或变相经营矿权;“异化”为政府“一口价”,或市场公开叫“价”。价款“异化”的主要影响：地方政府截留和挤占全民所有的资源权益,并使其造成隐性损失;抑制着矿业权有效需求;成为出资勘查者能动性发挥的严重障碍,制约着矿产勘查开采发展;严重影响着地方政府形象。消除价款“异化”的建议：进一步加强对地方政府相关人员矿业法律法规及相关政策的宣传教育;推进矿产资源税费改革,完善矿产资源补偿费收取标准;规范地方政府矿业权出让行为,防止经营或变相经营矿业权。     

Modelling Intercontinental Tourism Consumption in South Africa: A Systems‐of‐Equations Approach

This paper investigates the pattern of inbound tourists' consumption in South Africa, examining four main intercontinental markets and five different tourism goods. The empirical investigation develops an almost ideal demand system (AIDS) model and it extends recent research by allowing tourists to base their spending decision on the real effective price differences between South Africa and their home country. The results show that tourist spending in South Africa is a luxury good, and tourists react normally to a change in the relative price of goods. The cross‐price elasticities suggest that the preferences of different markets influence their view of substitutability and complementary effects between various products in South Africa.     

人口结构对住宅价格的影响——基于北京地区的实证研究

文章以北京市为例,使用1990—2011年北京地区人口结构和商品住宅价格数据,分析该地区人口结构变量对于房价的动态影响。文章发现,北京地区房价受到劳动人口比重、人口城镇化率、第三产业从业人口比重等三个人口结构变量的显著影响。其中,劳动人口比重对于房价的正向影响持续最短;第三产业从业人口比重对于房价的正向影响持续最长,影响力度也是最大;同时,人口结构变量整体对于房价的影响具有长期性。     

农产品调控中价格关联分析--以生猪与玉米价格为例

文章运用协整检验、格兰杰检验、VAR模型、脉冲响应函数等方法,对我国玉米和生猪的价格关系进行实证研究.结果显示玉米价格与生猪价格具有长期正向的均衡关系;生猪短期价格变动又受到短期玉米价格变动和前期生猪价格偏离长期均衡关系的影响;玉米价格的波动会影响生猪价格波动,但生猪价格变动对玉米价格影响较小.玉米价格的波动对生猪价格的影响具有3~4季度的时滞.基于上述结论,提出了相应的政策建议.     

Exchange Rate Regimes: Middling Through

Abstract

The appropriate exchange rate regime, in the context of integration of currency markets with financial markets and of large international capital flows, continues to be a policy dilemma. It is found that the majority of countries are moving towards somewhat higher exchange and lower interest rate volatility. Features of foreign exchange (forex) markets could be partly motivating these choices. A model with noise trading, non-traded goods and price rigidities shows that bounds on the volatility of the exchange rate can lower noise trading in forex markets; decrease fundamental variance and improve real fundamentals in an emerging market economy (EME); and give more monetary policy autonomy. Central banks prefer secret interventions where they have an information advantage or fear destabilizing speculation. But in the model discussed in this article, short-term pre-announced interventions can control exchange rate volatility, pre-empt deviations in prices and real exchange rates, and allow markets to help central banks achieve their targets. The long-term crawl need not be announced. In conclusion, the regime's applicability to an EME is explored.

农产品价格新一轮上涨的经济学思考

2003年下半年,我国农产品价格出现了自1996年以来的首次全面大幅上涨,并持续至今。应如何看待这一轮的农产品价格上涨?其直接的原因可以解释为市场机制作用中供求关系变化。然而,透过这个直接的表面原因,我们可以看到农产品价格上涨其实凸现出我国农业发展相对滞后这个更深层次的经济发展过程中的重大矛盾。加快农业发展,保持农业非农产业的平衡发展是国民经济持续稳定增长的必然要求。     

Are Offshore RMB Arrangements the Basis for a Long-term Exchange Rate System without Convertibility？

This paper discusses China's relatively new structure of dual onshore and offshore RMB markets. Its distinguishing feature is both offshore trading at exchange rates that are market determined and onshore trading at exchange rates anchored at the official spot rate with capital account inconvertibility. We note that thus far the CNH and CNY spot rates have largely tracked each other, suggesting that the shadow price on the convertibility constraint onshore and also the offshore diversification benefit is close to zero. However, this could change in the future. We discuss the potential for the offshore RMB market to grow with trade settlement and bilateral swap arrangements in RMB, which would provide a big enough pool of liquidity for the RMB to become a vehicle currency and reserve currency. These potential developments will be restrained by onshore inconvertibility, but moving to convertibility seemingly implies major change in China's financial structure and the offshore RMB arrangements are only a small first step along this path. Crucial in this evolution of arrangements will be future Chinese growth performance and the relative attractiveness of onshore inconvertible but offshore marketable RMB relative to the debt laden and slow growth currencies of the USA, the EU and Japan.     

山西省经济增长与煤炭生产量、消费量的相关性分析

利用19782004年的相关数据,对山西煤炭年产量、年消费量与山西经济增长进行相关性分析,认为山西省的煤炭生产量与GDP增长不具有长期均衡关系,而山西的煤炭消费量与GDP增长有着很好的同步关系,煤炭消费量的变化最终影响了山西的经济增长。该结论解释了山西煤炭的“资源诅咒”现象。山西资源经济要健康地可持续发展,一种符合可持续发展理念的现实选择即是在科学的煤炭价格机制下大力发展循环经济。     

中国移动通信业价格竞争本质解析

中国移动通信业的价格竞争,经过了无价格竞争阶段、显性价格竞争阶段、隐性价格竞争阶段、后价格竞争阶段的演化,体现了制度调节与市场选择并行的内在规律性,也增进了市场协调、提高了市场效率。中国移动通信业价格竞争具有非合作博弈的特性,行业管制与市场选择共同推动了竞争的有序化。因此,要实现中国移动通信市场的有效竞争,市场机制的作用是有限的,还离不开适当的政府行政参与下的不对称管制政策,而且不对称管制政策也需要根据市场变化进行调整和改进。
