Abstract ：
The reuse of recycled aggregate concrete (RAC) is being researched all over the world and lots of works are focused on the notched specimen to study the crack path of RAC. A mathematical algorithm of RAC meshing was presented to explore the failure pattern in RAC. According to this algorithm, the interfacial transition zone can be defined to be an actual thickness at the micron level. Further, a new finite element method (FEM) on the complementary energy principle was introduced to simulate the mechanical behavior of RAC's mesostructure. The compliance matrix of the element with any shape can be calculated and expressed to be a uniform and explicit expression. Several numerical models of RAC were established, in which the effecting factors of the prenotch size, thickness of ITZ, and the distance from the prenotch to the aggregate were taken into account. Hereafter, these RAC models were subjected to uniaxial tension. The effect of the aforementioned factors on the crack path was simulated. The simulated data manifest that both the mesh mode of RAC and the FEM on complementary energy principle are effective approaches to explore the failure pattern of RAC. The size of the prenotch, thickness of ITZ, and distance from the prenotch to the recycled aggregate have a powerful influence on the path and distribution of the isolated crack, width and length of the crack path, and the shape and path of continuous cracks, respectively.

Abstract ：
将高铁开通作为准自然实验,以2005～2017年286个地级及以上城市的面板数据为样本,从生产性服务业集聚和产业结构变迁视角探究高铁开通对劳动生产率的影响,并运用双重差分估计(DID)和倾向匹配得分双重差分估计(PSM-DID)等方法对高铁开通与劳动生产率进行实证分析和稳健性检验.结果发现:高铁开通对劳动生产率具有显著正向影响,且影响程度在不同地区和不同人口规模城市存在异质性;随着生产性服务业集聚从专业化向多样化转变,高铁开通对劳动生产率的正向影响逐渐加强;同时,高铁开通能够缓解产业结构高级化和合理化对劳动生产率产生的负向影响.

Abstract ：
Background: The proportion of government healthcare expenditure in China increases due to rapid economic development in recent years. The growth of government healthcare expenditure can promote physical health improvement of human capitals and thereby facilitate economic growth. Hence, exploring the effects of government healthcare expenditure on economic growth is important. Methods: Spatial correlation of economic growth under different spatial weights was tested, and the effects of government healthcare expenditure on economic growth were analyzed by constructing a spatial Durbin model with the panel data of 31 provinces in China gathered from 2005 to 2017. Results: Government healthcare expenditure in China significantly and positively affects economic growth under three spatial weight matrices. The spatial weight of economic distance influences economic growth more significantly compared with the 0-1 spatial weight and the spatial weight of geographical distance. The total and the direct effects of government healthcare expenditure are significantly positive. Furthermore, the direct effects are significant, whereas the indirect effects show different degrees of significance. Conclusion: The total effect of government healthcare expenditure on economic growth is significant and positive, with direct effects exceeding the indirect ones. Hence, the China's government must continue to increase financial investment to public health services to promote high -quality economic growth in the country.

Abstract ：
Based on the objective-weight value-assigning method, by means of establishing one comprehensive index system from four dimensions, namely natural endowment, flow input, output capacity and facilities' mechanism, this paper makes a series of experimental tests on the actual agricultural competitiveness within the 29 provincial-level areas of China from 2000 to 2016. And with application of spatial measurement model, it also makes a profound analysis upon spatio-temporal evolving rules and factors influencing China's agricultural competitiveness in hope for offering certain theoretical supports for formulating a series of targeted and differentiated agricultural competitiveness upgrading policies in the near future. The results of analysis show that: (1) China's agricultural competitiveness, featured by obvious spatial auto-correlation, is on the rise. The spatial spillover intensity presents an inverted 'U-shaped' pattern. And the two sub-competitiveness indexes, namely flow input and output capacity, still keep on the upside. The overall resource endowment is relatively stable and the facilities' mechanism is witnessing a fluctuant increasing process. (2) The agricultural competitiveness in the central and western provinces continues to decline as that in the eastern provinces rises rapidly, which presents an apparent polarization. And the local-spatial clustering pattern is dominated by HH clustering mode and LL clustering mode with the characteristics of stronger stability and serious path dependency. (3) Multiple factors, including farmers' income, household-consuming level, economic basis, R&D input, planting structure and grain-variety selection, have direct effects on the spatio-temporal evolution of provincial agricultural competitiveness. At the same time, the above factors have indirect spillover effects on other provinces. (4) We should give full play of the current demonstration effect and diffusion effect brought by the agricultural competitiveness and related influencing factors to push future optimal allocation of agricultural resources, promote subsequent rational flow of the existing agricultural producing factors and plan finally-balanced development of agricultural competitiveness. © 2020, Science Press.

Abstract ：
通勤出行是城市居民最基本和最重要的出行目的,通勤出行时间价值是评价通勤出行者对交通方式选择的重要参数之一,以累积前景理论为基础,将通勤出行时间价值引入广义出行成本函数中,以权重函数和改进的广义出行成本函数作为交通方式选择模型的依据,并在模型中自定义广义出行成本参考点,选择累积前景值最大的前景作为出行者最优决策.分别基于"期望效用最大化理论"和"累积前景理论"对通勤出行者在三种不同出行场景下进行仿真模拟,研究最优交通方式选择行为.研究结果表明:期望效用理论框架下,通勤出行者的交通方式选择行为不受出行场景的影响,累积前景理论更适用于出行方式选择行为的研究.构建以通勤出行时间价值为核心变量的交通方式选择模型,可帮助通勤出行者选择合理的交通方式,并为政府及相关部门制定交通管理规划和实施缓解交通拥堵政策提供依据.

Abstract ：
In this paper, we estimated affecting and important variables of fiscal and monetary policy on economic growth with comparing 3 models (BMA), (DMA) and (DMS) base on accuracy review of estimate model (MSFA), (MAFA). We have understood (BMA) model is an optimal model due to lower prediction error indicators that have shown in table [1]. So we identified the most important and affecting variables on economic growth with considering 62 indicators base on empirical data for determining affecting variables on economic growth, that with using BMA model. By doing the calculations and investigating the effect of 62 factors that have been effective in empirical studies on economic growth, it has been determined that the effect of 11 variables will be meaningful and these variables have always retained their effect, and in the presence of other variables, they have retained their effect. These variables are determined according to the posterior probability (i.e., the highest importance in explaining the economic growth and in other words the most likely to be present in the model). Capital Investment(K), Employment(L), Liquidity(M), Interest Rate(R), Inflation Rate(P), Government Expenditure(G), Balance of Payments (BP), Taxes(T), Oil Revenues (Troil), Gini Coefficient (Gni) and Saving Rate (S) are the affecting and important variables of fiscal and monetary policy on economic growth.

Abstract ：
This article selects 2000-2016 panel data of 31 provinces and cities in China, a dynamic space durbin model to explore the traffic infrastructure influence on inclusive economic growth, this study adopts the method of nonparametric measure inclusive growth that is total factor productivity (TFP), the results show that there is significant 'Time inertia' and 'space spillover' effect, Transportation infrastructure has significant positive spatial correlation. The relationship between highway infrastructure and inclusive economic growth is 'inverted U', which will promote the inclusive economic growth of this province. The influence of railway infrastructure on inclusive economic growth shows marginal increasing effect, and it also has positive spillover effect on inclusive economic growth of neighboring provinces. The conclusion of the study has important policy implications for China to increase investment in transportation infrastructure and promote inclusive economic growth in China. © 2019 ACM.
