Does Medical Equipment Expansion Lead to More Diagnostic Services? Evidence from China’s Sichuan Province

A major goal of China’s healthcare reform is to control the increasing healthcare spending, much of which can be attributed to the overuse of diagnostic tests and has been relatively less studied in the literature. This article analyzes the correlation between medical equipment expansion and the increase in diagnostic test expenditure in China, using Sichuan Province as an example. County-level data aggregated from hospitals’ annual reports in Sichuan Province from 2008 to 2012 were used. The results show a positive correlation between the expansion of medical equipment and the increase in diagnostic test expenditure. Our study provides implications on reforming China’s healthcare delivery system and medical equipment regulation policies.

Determining the integrated volatility via limit order books with multiple records

The integrated volatility plays an important role in risk management and portfolio selection, the estimation methods regarding the quantity have been widely investigated, either under low-frequency data or high-frequency data, or a combination of both. In this paper, we propose a measure for the integrated volatility via limit order book data with possible presence of multiple records. The estimator is valid under mild conditions and it is easily implemented. The finite sample performance of the proposed estimator has been verified by simulation studies and we apply the method to some real high-frequency data-sets as well.

Who benefit from government-led microfinance projects? Evidence from rural China

Drawing from a unique dataset of 2356 Chinese villages, this paper assesses the anti-poverty effect of the largest government-led microfinance project in the developing world. We find that the project can significantly increase the income level in the targeted villages. The main engine of the project lies in the expansion of access to nonfarm activities. We also highlight the importance of institutional circumstance in the effectiveness of the project. Specifically, a more democratized village with less political connection to local governments reaps more benefits from its participation.     

高利率捍卫汇率稳定理论研究综述

按照传统观点,在遭受投机攻击时,中央银行的典型做法是提高短期利率来捍卫本国货币和汇率制度.但批评者认为,高利率会增加经济增长的成本,反而容易引发信用恐慌和产出减少,使投机者更有动机进行攻击,最后在外汇储备即将耗尽前,中央银行权衡得失后不得不实行浮动汇率制.尽管两方的争论越来越激烈,但大量的实证研究表明,没有哪种说法是决定性的,反对的观点正逐渐取得上风.

乡村旅游开发下农户生计适应变化与影响机理研究*——以延安市乡村旅游为例

［目的］以延安市3个典型乡村旅游地为例,结合可持续生计分析框架和适应性理论,分析农户在乡村旅游扰动下的适应策略与适应模式,定量测度不同适应模式农户的适应结果。厘清农户未来生计策略选择的影响因素及其机制,提出促进农户及乡村旅游地可持续发展的对策。［方法］通过参与性农户评估法及二元回归分析法分析影响农户未来生计策略选择的因素。［结果］（1）旅游开发造成案例地农户自然资本丧失,失地农户由务农或务工为主的单一适应方式向兼业型与非农型转变,分化为4种不同类型的农户,且各类农户在各描述指标方面差异显著。（2）农户的生计资本衡量3个社区旅游开发后的适应结果,生计资本普遍较低且内部各维度差异明显。对比4类农户适应结果可得：复合生计型>务工主导型>旅游服务型>社会保障型。（3）通过二元逻辑回归模型深入解释当下适应结果对农户未来生计策略选择的影响,物质资本、金融资本和社会资本均影响农户选择意愿,其中可借款人数是最关键的影响变量。［结论］农户在旅游开发背景下生计动态适应的影响机制为旅游开发及基于此补偿制度是农户现在生计适应活动的外部起因,按照适应类型以及收入比重,分化为4种模式农户; 现行生计适应策略使农户适应结果迥异,生计资本的储量和结构差异显著,这种差异是农户未来生计选择的直接动因; 3个社区不同类型的旅游开发模式是农户未来生计策略选择分异的推动力量。
