A2 The correlation of Innovation activities and R&D activities in each year in the period In particular, the relationship between innovation activities and R&D activities is described in each year (Figure 3.19) There seems to be a slightly positive relationship between innovation activities and R&D activities This positive relationship may be more revealed in the year of 2010, 2011 and 2013 In comparison to the average level of innovation activities and R&D activities in the period, there may be more sectors having R&D activities in 2010, but more sector having innovation activities in 2014

period The positive correlation between innovation activities and R&D activities seems to be clearer in consideration of each sector (Figure 3.20) Some sectors such as sector number 41 and number 67 had both R&D activities and innovation activities to be higher than the average level of all sectors in all years in the period The innovation activities in 2013 seem to be below the average level in all sectors, except the sector number 41 and number 45 xxix B Spatial Regression Model in analysis on Knowledge Spillover among Sectors B1 General idea of Spatial Regression Model Spatial Regression Model has become a prominent tool for measuring spatial spillover It is widely acknowledged that what occurs in one region may be related to what happens in neighboring regions Several economic and socio-demographic variables may be referred to spatial clustering or geographic-based correlation such as unemployment, crime rates, house prices, per capital health expenditures and the alike (Solle Olle, 2003; Moscone and Knapp,2005; Reveilli,2005; Kostov,2009; Elhorst and Freret,2009; Elhorst et al.,2010) It is obvious that unemployment, crime rates or house prices in this region may have some effects on that in other regions These regions could be countries, states, census tracts or zip codes As stipulated by Tobler (1979), everything is related to everything else, but closer things more so These relations may be observed and analyzed by spatial regression models In spatial relations, the variable change for a specific unit may have effect on the change of other units that is regressed by different typical spatial models The change in dependent variable of this unit may be correlated with that variable’s change of other units This case is appropriate with the application of Spatial Autoregressive Model (SAR) In other case, the change in unobserved factors of this unit may be affected by the change in these factors of other units that is solved by Spatial Error Model (SEM) Besides, when there exists the effect of an explanatory variable’s change for a specific unit on the unit itself and, potentially, all other unit indirectly, Spatial Durbin Model (SDM) is prominent method to explore these relations In general, spatial regression models determines the relations among units basing on the correlation matrix that indicates which regions are spatially related with a given region This is usually a square symmetric RxR matrix xxx with (i,j) element equal to if regions i and j are neighbors of one another, and zero otherwise The diagonal elements of this “spatial neighbors” matrix are conventionally set to zero Depending on the border between regions, LeSage and Pace (2009) pointed out four ways to construct such a matrix including linear contiguity, rook contiguity, bishop contiguity and queen contiguity Besides, distance-based criteria is also used to determine neighboring relations among regions This approach can be expanded in a lot of ways by different distances or weights The usage of different methods in determining the matrix depends on the context In practice, the spatial neighbors’ matrices are usually slightly transformed into spatial weights matrices The most common transformation method is to make the sum of each row in the neighbor matrix to be unity In this method, called “row-standardization”, each element in a row is divided by the sum of the elements in the row Therefore, a spatial weights matrix W, with element wij is defined by !H = Depending on the method, the value of !zH is determined differently Under border approach, !zH is equal to when two regions satisfy the criteria of the same border Another typical criterion to define ! zH is distance-based contiguity with d ij to be the distance between (centroids of) regions i and j !zH is defined to be if dij
