陶二煤矿突出煤层石门反向揭煤技术研究

在突出矿井突出煤层石门揭煤过程中,由于穿越石门和煤门的距离长,工程周期长,揭煤时诱发突出危险的可能性大,而且在放炮揭煤时很难一次揭穿煤层,极易发生延期突出,一直以来是煤矿防突技术难题,给生命和财产带来巨大损失。陶二煤矿利用石门反向揭煤技术安全快速揭开高突煤层,具有抽放时间短、节省岩石钻孔工程量等技术优点,为煤与瓦斯突出矿井石门揭煤探索出一条安全、快速的技术途径。     

Saving–investment correlations, capital mobility and crowding out: some further results

This study attempts to reassess the evidence on the degree of capital mobility and crowding out by applying a varying coefficients model to data on 19 OECD countries over the 1971–1999 period. Our period-specific results strongly support the crowding-out effect as well as the low capital mobility argument for this group of countries as a whole. However, the strength of the crowding-out effect appears to weaken and the degree of capital mobility to increase in the 1990s as compared to the 1970s and 1980s. We also classify countries into five groups according to the relative size of the government sector. Our group-specific results indicate that the degree of capital mobility is generally lower and the crowding-out effect generally stronger, in country groups with smaller governments. The differences are especially evident when we compare the group with largest government size with all other groups, those differences between the latter being much more modest. However, significant differences in the country-specific results suggest that it is prudent to be cautious when we draw conclusions about crowding-out and capital mobility for specific countries from the period-wise or group-wise results. This is particularly important in drawing policy implications for specific countries.     

企业“走出去”战略机理探讨——以海宁市民营企业为例

金融危机为外向型经济成熟度较高的地区带来了发展机遇和挑战,政府应大力实施"走出去"战略推动企业转型升级。本文对"走出去"战略的机理作了理论阐述,并对海宁市民营企业进行了案例研究。"走出去"战略顺应企业成长规律,顺应经济发展要求。政府在实施"走出去"战略时应及时出台政策法规、加大财政支持力度、建立统筹协调机构、加强监管以降低民营企业境外投资的风险,激活民营企业境外投资的动力。

我国产权交易市场的特征及其市场失灵问题解析

市场经济条件下的市场调节功能失灵是普遍存在的现象,必须依靠政府监管和调控才能有效克服。我国现行产权交易市场的基本特征表明,国有资产所有者非人格化缺陷是我国产权交易市场失灵的最主要原因。必须尽快健全和完善我国国有资产监督与管理的法律体系,为各级国有资产管理部门履行出资人职责提供立法依据,建立起一个在政府有效监管下的行业和企业自律的产权交易市场。

The impact of government debt on the long-run natural real interest rate – a quantitative evaluation

Persistently low natural real interest rates are a problem for monetary policy and financial stability. I analyse to what extent a permanent increase in government debt that is financed by higher taxes could raise the long-run natural real interest rate. As a measurement tool, I use an incomplete markets model with capital and government bonds. Increasing the public debt/GDP ratio by one percentage point raises the real interest rate by between 0.4 and 1.5 basis points, depending on the degree of inequality generated by the model and the tax instrument used to balance the government’s budget constraint. I also show that the interest rate effect of a change in public debt/GDP predicted by the model is significantly smaller than its empirical counterpart for the US, due to the fact that the model understates the empirical fraction of households that are constrained in their consumption decision.     

我国财政支出规模变化的分析及其合理控制

文章对我国改革开放以来财政支出规模的变化趋势进行了实证分析,揭示了我国财政支出规模下降的背后仍然是政府实际支配资源规模的扩大,对这种变化趋势的合理性进行了分析判断,剖析了我国“财政之谜”(财政支出规模下降而企业负担重)的实质,给出了我国适度财政支出规模的基本要求及界定标准,提出合理控制我国财政支出规模的基本思路就是根据公共财政的内在要求,系统改造现行财政支出制度安排,构建符合公共财政要求的公共财政支出制度框架。     

Credit card cash‐out as informal financing: Evidence from China

Using a proprietary account‐level database from a commercial bank in China, we document that credit card holders can ease their credit constraints through the practice of cash‐out based on bogus transactions using credit cards. We find that such behaviour might be beneficial to both cardholders and banks. First, we find that a 1% increase in the cumulative number of credit card cash‐out transactions lowers the probability of default by 9.59%. Second, for private businesses, a 1% increase in the number of abnormal cash‐out transactions lowers overdue risk by 13.45%. Third, by lowering the overdue risk, the card‐issuing bank earns a larger profit. Our results are consistent with the notion that unconventional credit card cash‐out can mitigate the extent of capital misallocation in emerging markets.
