| Summary/Abstract |
Is the spatial concentration of manufacturing activity able to enhance firm-level productivity? This question is particularly relevant to production in China, which has a huge territory and population, but a skewed distribution in terms of urban-rural development. This paper aims to examine the dynamics of industrial agglomeration and the impact of agglomeration on firm-level productivity in China's textile industry by using a firm-level panel dataset from 2000 to 2005. First, the average value of the Ellison-Glaeser (EG) index (city level) is found to be approximately 0.00019. Moreover, the calculated city EG index of spatial concentration for each year exhibits a decreasing trend of spatial agglomeration for garments and other fiber products, but an increasing trend for the textile industries' agglomeration in China. The above findings are similar to the findings of Lu and Tao (2009). Secondly and importantly, this study finds an inverted U-shape relationship between agglomeration and productivity. It suggests that while industrial agglomeration enhances firms' productivity, agglomeration diseconomies may appear if the degree of agglomeration is too high.

| Summary/Abstract |
This paper investigates the regional hospital efficiency in China during the 2002-2008 period, especially for how the health insurance reform of New Rural Cooperative Medical System (NRCMS) impacts on efficiency. Adopting the non-parametric technique of data envelopment analysis (DEA) to handle the feature of multiple outputs and undesirable outputs in the hospital industry, empirical estimates indicate that hospital efficiency is moderate that increased slightly from 0.6777 to 0.8098 during the sample period. However, it ranges widely from 0.396 to 1 across provinces. The regression analysis on examining determinants of efficiency suggests that a higher proportion of for-profit hospital and high quality hospital is helpful to enhance technical efficiency. We find a negative relationship between government subsidy and efficiency for coastal regions. While technical efficiency varies considerable across provinces, there is no significant difference between coastal and non-coastal regions being found, after controlling for other variables. Crucially, the medical reform of NRCMS overall has a significant efficiency-enhancing effect, particularly for non-coastal regions, ceteris paribus. It highlights the effectiveness of NRCMS on promoting medical service accessibility for rural residents.

This paper analyzes the dynamics of China's productivity for the period 1996-2004 with a newly developed methodology - generalized metafrontier Malmquist productivity index (gMMPI). Implementing the gMMPI, this paper reviews the inequality of the coastal and non-coastal provinces, as well as the latent impact of scale efficiency change (SEC) for China. Using provincial data for the years 1996-2004, the empirical results are as follows. On average, China demonstrates an annual 3.191% productivity change, which is lower than 4.729% for the conventional MPI and accounts for about 26.508% of output growth over the period 1996-2004. Most of this change is propelled by technical progress, while a fraction is driven by the adjustment in production scale, and the efficiency change has an adverse effect. Furthermore, regional inequality is also found in this empirical work, and the productivity change of the coastal region is actually stronger than that of the non-coastal region. This paper also casts some focus on the China Western Development policy. Indeed, we do not find any outstanding achievement from the policy in the sample period, except that the west region sustained its rate of productivity change after 2000. Moreover, the SEC is found to be trivial in the advanced coastal region, but plays an important role in the relatively laggard non-coastal region. The implication of the positive SEC in the non-coastal region means that China's Western Development policy will improve the scale efficiency and the TFP growth of the west region.

This paper analyzes technical efficiency in China's banking system by large banks and small city banks as well as the pre-WTO and post-WTO accession periods. Using an unbalanced panel dataset for 63 banks over 1997-2006 and employing the stochastic frontier function approach, the empirical results reveal that the new entrants, small city banks, experienced a slightly higher efficiency score than incumbent large banks, on average. Compared with the pre-WTO accession period, the efficiency score is found to have improved significantly after entry into the WTO as a result of the competition effect. This competition effect is particularly relevant for small city banks. Finally, determinants of X-inefficiency are examined.

| Summary/Abstract |
The establishment of science parks is a vital strategy to develop high-tech industries and facilitate innovations in China. The success of a science park depends heavily on its supportive environment, suggesting that it is hard to replicate everywhere, while China has established many science parks across regions in the past decade. This study evaluates the degree of misallocation in research and development (R&D) and its determinants across science parks in China. Based on an unbalanced panel data of 145 science parks for the period 2007–2014, we find that the overall R&D efficiency has decreased sharply since 2011 when China began to initiate many new science parks. The newly constructed science parks exhibit a lower R&D efficiency than their incumbent parks, suggesting a considerable misallocation in R&D resource caused by expanding science parks everywhere. We further investigate the determinants of R&D misallocation and find that park characteristics and environmental characteristics matter. Parks which are larger, older, and having a higher human quality experience a lower R&D misallocation. Parks with closer R&D collaboration with universities or research institutes, particularly with universities, exhibit a lower R&D misallocation.

| Summary/Abstract |
As China adopts a government-supported agglomeration model to develop high-tech industries, it is crucial to examine whether the spatial concentration of manufacturing and R&D activities enhance firm-level productivity. Based on a panel dataset of Chinese electronics firms from 2005 to 2007, the calculated Ellison-Glaeser (EG) index indicates that both production and R&D activities are highly spatially concentrated. Crucially, we find that production agglomeration has a positive relationship with firms' productivity, especially for smaller firms. In contrast, R&D agglomeration seems to negatively relate with productivity. It implies that the possible congestion effect and/or free rider problems erode the benefit derived from knowledge spillovers.

| Summary/Abstract |
This paper aims to systematically investigate the impacts of strengthening intellectual property rights on patenting in China's high-technology industries and to explore the potential differences in response to patent reform by ownership. Empirical results show that the estimated patent elasticity of R&D is lower than that for OECD countries, indicating relatively low R&D productivity for China's high-technology industries. The direct innovation effect of technology imports is negative, while the absorptive ability embodied in R&D helps in gaining external sources of knowledge, thus contributing to innovations. Specifically, strengthening intellectual property rights can induce more innovations in terms of patents in China's high-technology industries and is particularly relevant to foreign-owned high-technology enterprises.
