A shovel comprising: a lower traveling structure ; an upper swing structure mounted on the lower traveling structure ; an engine mounted on the upper swing structure ; a hydraulic pump configured to be driven by the engine ; a hydraulic actuator ; an operating device configured to operate the hydraulic actuator ; and a control device configured to control a discharge quantity of the hydraulic pump through negative control, wherein the control device is configured to change a control characteristic of the negative control according to details of an operation on the operating device , the control characteristic of the negative control is determined by an inclined line (GL) that represents a correspondence between a control pressure (Pn) and a command value (Qn) for the discharge quantity of the hydraulic pump , the control pressure (Pn) being a pressure of hydraulic oil on an upstream side of a throttle placed in a center bypass oil passage , an upper end point (A) of the inclined line (GL) is expressed by a maximum command value (Qmax) that is an upper limit of the command value (Qn) and a first set pressure (Px) of the control pressure (Pn) of the negative control, a lower end point (B) of the inclined line (GL) is expressed by a minimum command value (Qmin) that is a lower limit of the command value (Qn) and a second set pressure (Py) of the control pressure (Pn) of the negative control, characterized in that the control device is configured to perform at least one of: changing a position of the upper end point (A) by varying the first set pressure (Px) with the command value (Qn) being fixed at the maximum command value (Qmax); and changing a position of the lower end point (B) by varying the second set pressure (Py) with the command value (Qn) being fixed at the minimum command value (Qmin). a lower traveling structure ; an upper swing structure mounted on the lower traveling structure ; an engine mounted on the upper swing structure ; a hydraulic pump configured to be driven by the engine ; a hydraulic actuator ; an operating device configured to operate the hydraulic actuator ; and a control device configured to control a discharge quantity of the hydraulic pump through negative control, wherein the control device is configured to change a control characteristic of the negative control according to details of an operation on the operating device , the control characteristic of the negative control is determined by an inclined line (GL) that represents a correspondence between a control pressure (Pn) and a command value (Qn) for the discharge quantity of the hydraulic pump , the control pressure (Pn) being a pressure of hydraulic oil on an upstream side of a throttle placed in a center bypass oil passage , an upper end point (A) of the inclined line (GL) is expressed by a maximum command value (Qmax) that is an upper limit of the command value (Qn) and a first set pressure (Px) of the control pressure (Pn) of the negative control, a lower end point (B) of the inclined line (GL) is expressed by a minimum command value (Qmin) that is a lower limit of the command value (Qn) and a second set pressure (Py) of the control pressure (Pn) of the negative control, characterized in that the control device is configured to perform at least one of: changing a position of the upper end point (A) by varying the first set pressure (Px) with the command value (Qn) being fixed at the maximum command value (Qmax); and changing a position of the lower end point (B) by varying the second set pressure (Py) with the command value (Qn) being fixed at the minimum command value (Qmin). changing a position of the upper end point (A) by varying the first set pressure (Px) with the command value (Qn) being fixed at the maximum command value (Qmax); and changing a position of the lower end point (B) by varying the second set pressure (Py) with the command value (Qn) being fixed at the minimum command value (Qmin). <EOS>
